Built on our decades of expertise developing breakthrough noninvasive medical monitoring technologies, Masimo W1 is designed to aid valued hospital partners like Cambridge in accelerating their virtual hospital and telehealth programs – ultimately helping to improve patient outcomes while reducing the cost of care. We are excited for Cambridge clinicians and patients.” 

Cambridge University Hospitals NHS Foundation Trust launched its virtual ward program in 2022, as part of a National Health Service (NHS) England telehealth initiative designed to promote earlier patient discharge to the home. More than 20 specialties across the hospital now participate in Cambridge’s virtual program, which sends patients home with a variety of Masimo products – such as MightySat^® and wearable medical devices like Radius PPG^®, Radius Tº^®, and now Masimo W1 – that allow monitoring and vitals signs data to be relayed to clinicians back at the hospital. Via the Masimo SafetyNet clinician dashboard, hospital clinicians can keep an eye on their patients’ physiological status from afar, allowing patients to stay monitored in the comfort of their own homes. 

Dr. Iain Goodhart, Clinical Director of the Virtual Hospital Program at Cambridge University Hospitals NHS Foundation Trust, commented, “Masimo W1 will help us expand our Virtual Hospital program by offering continuous monitoring of oxygen saturation and pulse rate, as well as ECG spot-checking, in a comfortable, easy to use watch. We hope that, integrated with Masimo SafetyNet, the telehealth platform we already use, Masimo W1 can help support more confident patient discharge and management for patients who, before our Virtual Hospital program, might have needed to stay longer in the hospital. We’re excited to incorporate Masimo W1 into our telehealth practices.” 

Masimo W1 for use in medical applications is pending FDA clearance in the U.S.

Masimo Stork™ Delivers State-of-the-Art Baby Monitoring to the Home 

Irvine, California - May 1, 2023 - Masimo (NASDAQ: MASI) a global leader in pulse oximetry and other innovative noninvasive monitoring technologies, today announced the launch of Stork, a revolutionary home baby monitoring system. This innovative system offers parents insights into their baby’s health data, helping them learn more about and be better connected with their baby.

“When we set out in 1989 to reinvent pulse oximetry, we named the project ‘Stork’ because our hope was that this technology would help reliably bring healthy babies home to their parents,” said Joe Kiani, Founder and CEO of Masimo. “With Stork’s introduction today, we’ve taken our passion for newborn care and our innovative and groundbreaking technologies to craft a solution that we hope will give parents greater insights into their babies and help them live healthier lives. Parenting is the hardest thing one loves to do. With Stork, our goal is to improve the parenting experience through a seamless, thoughtful integration of advanced and trusted health technologies that bring real data to parents.” 

“We designed Stork so parents and their babies can stay connected, when they can’t be next to each other,” continued Mr. Kiani. “Today’s parents are technologically sophisticated and better educated about their babies than ever. They track their own health data and know how managing that data can help them understand more about themselves. With Stork, we bring them the highest quality data so that they can be vigilant and learn even more about their babies.” 

The Masimo Stork monitoring ecosystem, which comprises several components, will be available in multiple configurations. Masimo Stork Vitals+, the flagship solution, consists of a boot with sensor, video camera, and a mobile app.

The Masimo Stork boot is made from an ultra-soft, comfortable medical-grade silicone that conforms gently on the baby's skin and comes in three sizes to ensure a good fit. The boots are designed to grow with the baby (up to 18 months old). The sensors embedded in the Stork boot are the product of meticulous engineering to harness decades of expertise in newborn health to detect babies’ oxygen saturation (SpO₂), pulse rate, and temperature with remarkable accuracy and dependability.

Masimo Stork also features a 2K QHD-capable, high-resolution camera with a mobile app. The Stork camera provides outstanding nighttime vision and offers high-quality two-way audio through the camera, letting parents hear and talk to their babies as if they were right next to them. The camera is also equipped with room condition monitoring to accurately report room temperature, humidity, and noise levels. All components are connected to the Masimo Stork app, which allows parents to see their baby’s monitoring data and milestones; view summaries of averages and trends; and coming soon, share images directly with others. The simple and intuitive app contains built-in educational tools to empower parents with the confidence to know what’s important, when it’s important.

For consumers who do not require streaming video, the Stork Vitals solution replaces the camera with a health hub which connects the Stork boot and sensor to the Stork App, while providing two-way audio and the ability to monitor room conditions.

Masimo Stork is an ideal gift for new and expecting parents, for baby showers, or as a thoughtful gesture for those who want to track health indicators to get to know their baby better. The Masimo Stork system bundles range from $249 to $549 USD. Bundles are now available for pre-order in the U.S. at MasimoStork.com and will begin shipping in June 2023.

Masimo Stork is not for medical purposes.

The Masimo Story

34 years ago, two engineers undertook the daunting task of reimagining pulse oximetry in order to address an issue previously thought “unsolvable”: how to make pulse oximetry monitoring accurate and reliable on the most vulnerable patients of all, premature babies in the NICU. Their groundbreaking innovation, known as Masimo Signal Extraction Technology^®, or SET^®, has transformed patient care, reducing mortality and morbidity, and giving clinicians more time to focus on their patients and not their previously unreliable pulse oximeters.¹ Today, Masimo SET^® is used to continuously monitor more than 200 million patients a year around the world,² and is the primary pulse oximetry at 9 of the top 10 U.S. hospitals.³

Over the years, Masimo’s unwavering dedication to enhancing outcomes for the most delicate and youngest patients has resulted in significant reductions in neonatal blindness from retinopathy of prematurity,⁴ and significant improvements in screening newborns for critical congenital heart disease.⁵ Its original breakthrough innovation, SET^®, has been shown to outperform other pulse oximetry technologies in more than 100 independent and objective studies.¹ With Stork, which uses that same technology, Masimo now offers that same level of superior performance and reliability in a baby monitor.

Masimo Announces FDA Clearance of the Rad-G^® with Temperature 

Irvine, California - April 18, 2023 - Masimo (NASDAQ: MASI) today announced that the Rad-G^® with Temperature has received FDA 510(k) clearance. Rad-G with Temperature is a rugged, versatile, handheld monitor that provides clinically proven SET^® pulse oximetry, respiration rate from the pleth (RRp^®), and other important parameters alongside non-contact infrared clinical thermometry. With its long-lasting rechargeable battery, robust rubber casing, light weight, and the added convenience of integrated noninvasive forehead thermometry, Rad-G with Temperature makes it easier for care teams to quickly measure vital signs using a single, compact, portable device and make informed decisions anywhere patient assessment is needed. Rad-G with Temperature is designed for use in a variety of settings, including physicians’ offices, outpatient services, urgent care facilities, wellness clinics, and in first-responder scenarios, both indoors and in the field.

Joe Kiani, Founder and CEO of Masimo, said, “With Rad-G, we set out to create an accessible, high-quality care solution that could be used in a multitude of care settings to serve the five billion people on our planet that to date have not had access to pulse oximetry, let alone SET^® pulse oximetry. With the addition of temperature measurements, Rad-G is more versatile than ever, streamlining the assessment of multiple key vital signs. Having a product that is light, small, multifunctional, and ‘accurate when you need it most’ is crucial, and Rad-G was designed to be just that. With this FDA clearance, Rad-G with Temperature can now be deployed across the U.S., in addition to many other parts of the world, helping support clinicians in almost any care scenario.” 

The infrared thermometry offered by Rad-G with Temperature provides a host of benefits. Rad-G’s thermometer is non-contact and does not require probe covers or other disposable accessories. Its integration into the Rad-G platform eliminates the need for clinicians to locate a separate clinical thermometer to take body temperature measurements and ensures that many people can be seamlessly and efficiently screened for temperature, with one-touch operation, alongside oxygen saturation, respiration rate, and more, in the same session, using a single device. Designed from the start to maximize portability and battery life, Rad-G’s rechargeable battery provides an impressive 24 hours of operational use between charges – allowing clinicians to work in transport, emergency, and other challenging scenarios with confidence that the device will continue to function hour after hour. 

First developed in partnership with The Bill & Melinda Gates Foundation as a spot-check device for use in pneumonia screening, Rad-G with Temperature originally launched outside the U.S. Since its introduction in Europe, more than 100 global customers have adopted the device to help them assess patient status in a variety of care settings. Among other care scenarios, the National Health Service (NHS) England, which provides the majority of healthcare in England, uses the technology to support primary care assessments of unwell children in physician’s offices across the country. In a survey of 109 NHS England clinicians whose primary care facilities were using more than 4,000 Rad-G with Temperature devices, 85% of respondents scored Rad-G with Temperature as “Quite Easy” or “Very Easy” to use.¹

SpO₂ and PR monitoring on Rad-G is provided using clinically proven Masimo SET^® Measure-through Motion and Low Perfusion™ pulse oximetry, which has been shown in over 100 independent and objective studies to outperform other technologies.² SET^® is estimated to be used on more than 200 million patients a year³ and is the primary pulse oximetry at 9 of the 10 hospitals that top the 2022-23 U.S. News and World Report Best Hospitals Honor Roll.⁴ With Masimo SET^® technology in Rad-G, clinicians have access to accurate pulse oximetry measurements in the palm of the hand.

In addition to temperature measurements and Masimo SET^® oxygen saturation (SpO₂) and pulse rate (PR), the same SpO₂ sensor can be used to monitor respiration rate from the plethysmograph, with RRp. Difficulty breathing and fever are generally considered two of the earliest signs of patient deterioration, and Masimo believes that the availability of RRp and thermometry on Rad-G may play a role in assisting clinicians and public health officials as they seek to combat numerous types of illnesses, including pneumonia and other respiratory viruses.

Rad-G with Temperature can be used with a variety of reusable and single-patient use sensors. The universal direct-connect Rad-G reusable sensor, indicated for monitoring adult, pediatric, and infant patients, helps to eliminate the need to stock and carry multiple sensor types, increasing the device’s versatility and ease of use, especially in more challenging field environments. Rad-G with Temperature is also compatible with the vast portfolio of Masimo single-patient-use adhesive sensors—including Masimo RD SET^® sensors, which offer best-in-class accuracy specifications of 1.5% in conditions of motion and no motion—ensuring clinicians can customize their setup based on the unique needs of each care setting. In addition, Rad-G is designed to work reliably on all people, regardless of skin tone, from neonates and babies to elderly patients.

Masimo Opioid Halo™ Granted De Novo for the First and Only FDA-Authorized Opioid Overdose Prevention and Alert System 

Opioid Halo Is Indicated for the Detection of Opioid-Induced Respiratory Depression, with Escalating Alarms to Alert Loved Ones That Help Is Needed

De Novo Authorizes Both Over-the-Counter (OTC) Use, on Adults and Children Age 15 and Up, and Prescription Use

Irvine, California - April 03, 2023 - Masimo (NASDAQ: MASI) today announced that Masimo Opioid Halo™, an opioid overdose prevention and alert system, has been granted a De Novo by the FDA – making it the first and only FDA-cleared monitoring solution for detecting opioid-induced respiratory depression, the leading cause of death from opioid overdose. With the De Novo, Masimo also becomes the first winner of an FDA Opioid Innovation Challenge to have an authorized solution designed to help solve the U.S. opioid crisis. The De Novo authorizes Opioid Halo to be made available over the counter (OTC) without a prescription, for use on adults and children age 15 and up, and an Rx version for use by prescription from a healthcare provider. Opioid Halo advances the forefront of continuous monitoring through its unique Opioid Halo engine, an advanced pattern recognition algorithm which helps detect and quantify the risk of severe opioid-induced respiratory depression. Combined with its innovative distributed architecture, Opioid Halo helps to manage and send escalating alarms to family members, friends, and caregivers, notifying them that help may be needed due to an opioid overdose – including triggering an automatic wellness call, which may lead to EMS being dispatched.

Joe Kiani, Founder and CEO of Masimo, said, “We are very excited to be able to offer this solution to our fellow Americans and the community heroes who are helping to battle the opioid crisis – a crisis so devastating in its impact on the young that it has lowered overall life expectancy in the U.S. Now, with Opioid Halo, we hope to help make a big difference by providing a much needed tool that can help millions, whether they are taking prescribed opioids or struggling with illicit opioid use. In 2018, we were honored to be chosen by the FDA, based on our expertise in patient monitoring technologies, to develop a device that could help prevent opioid overdose, as part of their Innovation Challenge addressing the opioid epidemic. And today, we are delighted to have received the first De Novo for our response to that Innovation Challenge, Masimo Opioid Halo. Between then and now, the COVID-19 pandemic accelerated our development and refinement of the Masimo SafetyNet^® family of remote patient management and telehealth solutions, helping save many COVID patients’ lives. We thank the FDA for taking on the opioid epidemic and granting this De Novo – a clearance that is a huge step forward in preventing overdose deaths and helping to end the opioid crisis.” 

Opioid overdose is the leading cause of accidental death in the US, responsible for more than 80,000 of the approximately 100,000 drug-related deaths in 2021, from both illicit opioids, such as fentanyl and heroin, and prescription opioids. Hundreds of thousands more suffer non-fatal overdose events, or the loss of a family member or friend to opioids.¹ Opioids are readily prescribed in the US, with more than 143 million opioid prescriptions written in 2020,² because they can be an effective way to help people manage pain, including after surgery or for chronic conditions. However, opioids also carry serious side effects, especially opioid-induced respiratory depression – slowed or stopped breathing – which is the leading cause of death from opioid overdoses.³ Anyone taking opioids, prescription or illicit, is at risk of experiencing an accidental overdose, the signs of which are unpredictable and can be difficult to detect. 

Masimo Opioid Halo is designed to help family and friends identify the symptoms of an opioid overdose by detecting physiological markers present during opioid-induced respiratory depression and ideally, helping them know when it’s time to intervene – for example, by administering a potentially life-saving dose of naloxone. Opioid Halo can be used at home or in the hospital or another care setting, by patients prescribed opioids after surgery or managing a chronic or prolonged condition, as well as people suffering from opioid use disorder.

The Opioid Halo system consists of four components: 1) a tetherless, adhesive fingertip sensor; 2) a reusable Masimo SET^® pulse oximeter and Bluetooth^® chip; 3) a Bluetooth-to-Wi-Fi Masimo Home Medical Hub; and 4) a smartphone app. The fingertip sensor provides real-time monitoring for opioid-induced respiratory depression, enabled by the Opioid Halo pattern recognition algorithm and Masimo SET^®, Signal Extraction Technology^® – even during movement, when hands are cold, and on all skin pigmentations. Data from the sensor and chip are wirelessly relayed to the Masimo Home Medical Hub and the smartphone app, which continuously analyzes the user’s physiological data for trends and patterns associated with the physiology of an opioid-induced respiratory depression event to quantify the risk of an opioid overdose. As the level of risk rises, the app and hub provide alerts. Upon early onset, an audible and visual alarm, designed to trigger early intervention opportunities for the user to self-recover or get help, is provided. If the Opioid Halo risk score continues to worsen, in addition to the repeated alarms, automatic texts are sent to designated friends and family members, letting them know it may be time to intervene, for example by administering naloxone or taking other action. Finally, if the severity of the risk level progresses even further, there is an optional setting that can be activated during setup that enables a service center to place an automatic wellness call to the user, the outcome of which may lead to EMS being dispatched.

Kim Bennion, MsHS, RRT, CHC, FAARC, System Director of Research for Respiratory Care Clinical Services at Intermountain Health, a 33-hospital system based in Salt Lake City, Utah, said, “Painkillers often called ‘opioids’ can have negative side effects, including opioid-induced respiratory depression. Intermountain Health has demonstrated that home monitoring of post-surgical patients receiving opioids for pain can help identify issues earlier and avoid adverse outcomes.  As a registered respiratory therapist and leader in the field of opioid-induced respiratory depression in the post-surgical setting, we are excited that Masimo’s breakthrough device will be available for our patients.”

Ryan Hampton, a noted advocate, author, and person in recovery, said, “Joe Kiani and his team at Masimo are strong advocates for solutions to help end the overdose crisis. Opioid Halo is another breakthrough innovation that can help save lives by adding to the critical support tools for people who use drugs.”

“My son Parker lost his life after taking prescription opioids to manage his pain after a tonsillectomy,” said Yvonne Gardner, now a patient safety advocate. “No one warned us that this could happen. This technology can help save other parents from losing a child.”

Masimo CEO Kiani added, “For more than 30 years, Masimo has been empowering clinicians with life-saving technologies that improve outcomes for countless patients around the world. Opioid Halo furthers our mission to expand beyond the hospital and into the home, empowering everyday people with a solution that we believe has the power to improve and save many more lives.”

European Society of Anaesthesiology and Intensive Care (ESAIC) Recommends Noninvasive, Continuous Hemoglobin Monitoring

Technologies Like Masimo SpHb^® Offer a “Practical Approach” to Perioperative Blood Management and “Timely Detection of Changes” 

Neuchatel, Swirzerland - March 15, 2023 - Masimo (NASDAQ: MASI) today announced that updated guidelines published by the European Society of Anaesthesiology and Intensive Care (ESAIC) highlight the value of noninvasive, continuous hemoglobin (Hb) monitoring in helping clinicians manage perioperative bleeding. Referencing studies using technologies such as Masimo SpHb^®, the guidelines note that “the use of noninvasive Hb-monitoring methods may be a practical approach to monitor[ing] the Hb concentration continuously and without accumulating additional blood losses.”¹

Noting that in this area of care it is “essential to remain informed by the latest evidence,” the ESAIC, which has pledged to revisit its perioperative blood management guidelines at least every five years, has just published its updated findings, the result of a systematic review of research published from 2015 to 2021. Noting that managing bleeding during surgery is complex and “involves multiple assessment tools and strategies to ensure optimal patient care,” the guidelines cover numerous modalities, disciplines, scenarios, and patient populations – including how noninvasive, continuous hemoglobin monitoring offers a valuable way to improve blood management.

In the updated guidelines, the ESAIC notes a major drawback to measuring hemoglobin during surgery using blood gas analyzers and invasive blood sampling: “single measurements taken at different time points may not depict accurate values.” In addition, they note, excess blood sampling can lead to iatrogenic blood loss and hospital-acquired anemia. While noninvasive hemoglobin monitoring is not intended to replace invasive blood sampling, it may offer a “practical approach to monitor[ing] the Hb concentration continuously and without accumulating additional blood losses.” The guidelines also note its value “for trend analysis and to monitor changes in addition to laboratory-measured Hb concentrations during the intervals between invasive blood sampling and Hb measurements.” The guidelines continue, “Having access to continuous measurements of Hb concentrations offers timely detection of changes in Hb concentrations and adjustment, if necessary, in the clinical setting.”

In their summary of the guidance derived from their systematic literature review, the guidelines also note that when severe bleeding and volume shifts are expected or occurring, “continuous noninvasive haemoglobin monitoring may be considered for trend analyses and for reducing blood sampling for invasive laboratory measurement of haemoglobin concentration, especially in children.”

Launched in 2008, Masimo SpHb is part of the rainbow^® Pulse CO-Oximetry platform, available on a variety of Masimo Pulse CO-Oximeters^® and on devices from numerous third-party manufacturers, including Draeger, GE, Philips, and ZOLL. Utilizing multiple wavelengths of light, SpHb provides real-time, continuous visibility to changes in the hemoglobin trend between invasive blood samples. As part of patient blood management programs, SpHb has been found to improve outcomes in both high- and low-blood loss surgeries, such as reducing the percentage of patients receiving allogeneic transfusions,^2,3 reducing the units of red blood cells transfused per patient,^4-6 reducing the time to transfusion,⁷ reducing costs,⁸ and even reducing mortality 30 and 90 days after surgery by 33% and 29%, respectively (when combined with a goal-directed fluid therapy algorithm using Masimo PVi^®).⁹ The evidence of SpHb’s impact on outcomes spans the globe, now representing 7 countries on 4 different continents.^2-10 Today, Masimo SpHb technology supports clinicians and patient care in more than 75 countries.

Professor Kai Zacharowski, Ambassador and Immediate Past President of ESAIC and senior author of the guidelines, commented, “Noninvasive hemoglobin measurements now represent standard of care in many clinical scenarios. With their inclusion in the latest perioperative bleeding guidelines, we hope that more anesthesiologists and intensivists around the world incorporate this technology into their daily practice to help improve overall patient blood management.”

Professor Edoardo De Robertis, current President of ESAIC and co-author of the guidelines, noted, “The ESAIC holds the most prominent position in the community of anaesthesiologists and intensivists in Europe and elsewhere. We are pleased to share the updated guidelines with the goal of improving patient outcomes by focusing on the quality of care and patient safety strategies. Noninvasive hemoglobin monitoring has an important role throughout the perioperative period and in acute care, as it can provide trend data for more informed decision making. We look forward to seeing it adopted more widely for better patient care.”

Dr. William C. Wilson, Chief Medical Officer, Masimo, added, “With laboratory measurements, and even with bedside point-of-care hemoglobin testing, results are intermittent, sampling errors can occur, and performing these tests can be distracting during complex cases and while caring for critically ill patients. SpHb monitoring provides real-time visibility to hemoglobin levels throughout the continuum of care and has the advantages of trend analysis as well as reductions in workload and delay, enabling clinicians to adjust blood management and observe results simultaneously.”

Joe Kiani, Founder and CEO of Masimo, said, “Since its introduction 15 years ago, we’ve been heartened to see more and more clinicians around the world adopt SpHb as their standard of care, more and more clinical studies demonstrate its utility, and more and more esteemed organizations like ESAIC recognize the benefits of noninvasive hemoglobin monitoring. The result of years of development and continued refinement, powered by our expertise in advanced signal processing techniques, SpHb plays a critical role in our mission to improve patient outcomes, reduce the cost of care, and ultimately, improve life.”

SpHb is not intended to replace laboratory blood testing. Clinical decisions regarding red blood cell transfusions should be based on the clinician’s judgment considering, among other factors, patient condition, continuous SpHb monitoring, and laboratory diagnostic tests using blood samples.

New Study Finds That Masimo PVi^® Reliably Predicted Fluid Responsiveness in Young Children Undergoing Neurosurgery

Noninvasive, Continuous PVi Performed Well; Pressure-based Invasive Techniques Performed Poorly 

Neuchatel, Swirzerland - March 09, 2023 - Masimo (NASDAQ: MASI) today announced the findings of a prospective study published in Pediatrics International in which Dr. Ya-Fei Liu and colleagues at Peking University First Hospital in Beijing evaluated the ability of noninvasive, continuous Masimo PVi^®, alongside other dynamic parameters, to predict fluid responsiveness in children 1-3 years old who were undergoing major neurosurgery. The researchers concluded, “Volume-based PVi and ∆Vpeak [respiratory variation in aortic blood flow peak velocity] showed acceptable reliabilities for fluid responsiveness prediction in young children undergoing major neurosurgery, while pressure-based SVV [stroke volume variation] using FloTrac/Vigileo, Ea_dyn [dynamic arterial elastance], and PPV [pulse pressure variation] [did] not.”¹

Noting that dynamic variables have been shown to predict fluid responsiveness more accurately than static variables, and the critical importance of optimizing fluid administration in pediatric surgical patients, the researchers sought to evaluate and compare the performance of a variety of dynamic variables in such a scenario. The parameters evaluated were noninvasive, continuous PVi (pleth variability index, obtained from the photoplethysmographic waveform measured by fingertip pulse oximetry sensors and, in this study, the Masimo Radical-7^® Pulse CO-Oximeter^®), ∆Vpeak (obtained intermittently by Doppler echocardiography), SVV (measured by the Edwards Lifesciences FloTrac/Vigileo system), PPV (obtained from the peripheral arterial pressure waveform), and Ea_dyn (an index of arterial load). 

The researchers enrolled 60 patients, aged 1-3, who were undergoing major neurosurgery with mechanical ventilation set at a fixed tidal volume of 8 ml/kg. Following induction of anesthesia, during a hemodynamically stable period, the patients were administered 10 ml/kg of Ringer’s lactate solution, over 10 minutes; all variables were measured before and within five minutes of fluid loading. Patients with an increase in cardiac index (CI) of 10% or more were identified as a fluid responder. (CI was defined as stroke volume index multiplied by heart rate.)

The researchers identified 26 of the 60 patients as fluid responders. They found that baseline PVi showed “fair diagnostic accuracy” for CI-fluid responsiveness, with an area under the receiver operating characteristic curve (AUROC) of 0.775, p < 0.001. A baseline PVi cutoff value of 15% predicted CI-fluid responsiveness with 77% sensitivity and 68% specificity. Baseline ∆Vpeak was an “excellent predictor” of a CI increase, with AUROC of 0.982, p < 0.001, and a cutoff value of 9.6%. However, ∆Vpeak, which is dependent on the timing of echocardiograms, can only be obtained intermittently; the authors also note, as a practical drawback, that the limited availability of echocardiographic professionals “decreases its wide use in routine clinical settings.” The researchers found the other methods were either “poor” or “were not” predictors.

The researchers concluded, “Volume-based PVI and ∆Vpeak showed acceptable reliabilities to predict fluid responsiveness, defined by a CI increase, after anesthesia induction in mechanically ventilated young children undergoing major neurosurgery. However, pressure-based FloTrac/Vigileo-derived SVV, Ea_dyn, PI, PPV, and SVIc were not or [were] poorly reliable predictors. PVi’s noninvasiveness, continuity and acceptable predictability for fluid responsiveness could make it a potential aid in evaluating hemodynamic status, facilitating fluid administration, and developing optimal fluid management protocols in young children undergoing neurosurgery.”

Joe Kiani, Founder and CEO of Masimo, said, “From its inception, Masimo has focused on developing technologies that improve outcomes for the very youngest and most fragile of patients. This latest study on PVi – the second we are reporting on just this week! – adds to the body of evidence that PVi can help clinicians predict fluid responsiveness.”²

In the U.S., PVi is FDA 510(k) cleared as a noninvasive dynamic indicator of fluid responsiveness in select populations of mechanically ventilated adult patients. Accuracy of PVi in predicting fluid responsiveness is variable and influenced by numerous patient, procedure and device related factors. PVi measures the variation in the plethysmography amplitude but does not provide measurements of stroke volume or cardiac output. Fluid management decisions should be based on a complete assessment of the patient’s condition and should not be based solely on PVi.

New Study Evaluates the Use of Masimo PVi^® As an Indicator of Fluid Responsiveness to Guide Goal-Directed Fluid Therapy in Adult Neurosurgical Patients

Researchers Found That Noninvasive, Continuous PVi Was Equally Effective in Guiding Fluid Management As Stroke Volume Variation (SVV), an Invasive Method Requiring an Arterial Line

Neuchatel, Switzerland - March 6, 2023 - Masimo (NASDAQ: MASI)  today announced the findings of a prospective study published in the British Journal of Neurosurgery in which Dr. Ankita Dey and colleagues at institutions in Bathinda and Pondicherry, India evaluated the use of noninvasive, continuous Masimo PVi^®, as part of goal-directed fluid therapy (GDFT), to guide intraoperative fluid administration during neurosurgery – the first study to evaluate PVi in this surgical scenario – by comparing it to a parameter obtained invasively, stroke volume variation (SVV). The researchers concluded that “PVi and SVV are equally effective for guiding intraoperative goal-directed fluid therapy in adult neurosurgical patients scheduled for elective craniotomy for supratentorial brain tumors. However, PVi, being a noninvasive parameter, may be preferable.”¹. 

Noting the value of GDFT for neurosurgical patients in particular, but that most of the dynamic parameters traditionally used to guide GDFT, such as SVV, are invasive, requiring the use of an intra-arterial catheter (an arterial line, or “A-line”), which is associated with a variety of complications, the researchers sought to determine whether a noninvasive parameter, PVi, whose measurements are derived from the photoplethysmographic waveform, might serve as a reliable predictor of fluid responsiveness in such a population. PVi, or pleth variability index, is a measure of the variations in perfusion index over the respiratory cycle, and is indicated as a noninvasive, dynamic indicator of fluid responsiveness in select populations of mechanically ventilated adult patients.

To test their hypothesis, the researchers randomly divided 60 adult patients undergoing elective craniotomy into two groups: one whose intraoperative fluid administration was guided by PVi (n=29) and the other, by SVV (n=31). In the PVi group, patients were monitored using Masimo Radical-7^® Pulse CO-Oximeters^® with noninvasive pulse oximetry fingertip sensors. In the SVV group, SVV was invasively measured using an Edwards Lifesciences Vigileo/FloTrac device connected to a cannulated radial artery. The researchers compared the total amount of intravenous fluid administered during surgery, as well as serum lactate and serum creatinine levels at pre-determined time points, the brain relaxation score at dural opening and closure, and correlation between PVi and SVV values. They also compared duration of mechanical ventilation and length of hospital stay.

As noted in the table below, the researchers found that the volume of fluid administered intraoperatively was significantly higher in the SVV group. The other parameters and outcomes they measured were comparable between the two groups: serum lactate, serum creatinine, brain relaxation score, duration of mechanical ventilation, and length of hospital stay, as noted below. The researchers also observed “a moderate to strong correlation between SVV and PVi at corresponding points of time during the intraoperative period. This suggests that PVi, derived noninvasively from the pulse oximetry waveform, is a reliable indicator of fluid responsiveness.”

Outcome	PVi Group	SVV Group	p-Value
Volume of fluid administered	2139.3 ± 898.6 mL (mean)	3208.3 ± 1836.2 mL (mean)	0.005
Serum lactate level, over time	Ranging from 1.59 ± 0.91 to 2.73 ± 1.18	Ranging from 1.79 ± 0.97 to 2.44 ± 0.88	Ranging from 0.55 to 0.82
Serum creatinine level, over time	Ranging from 0.64 ± 0.14 to 0.66 ± 0.15 mg/dL	Ranging from 0.64 ± 0.17 to 0.71 ± 0.21 mg/dL	Ranging from 0.23 to 0.86
Brain relaxation score	2 (1-3) at dural opening, 2 (12) at dural closing (median)	2 (1-4) at dural opening and closing (median)	0.49 (opening) 0.33 (closing)
Duration of mechanical ventilation	19.09 ± 15.9 hours (mean)	27.9 ± 15.9 hours (mean)	0.1
Length of hospital stay	12.6 ± 19.26 days (mean)	16.4 ± 26.8 days (mean)	0.53

 

The researchers concluded, “Based on the findings of our study, we conclude that PVi and SVV are equally effective for guiding intraoperative goal directed fluid therapy in adult neurosurgical patients scheduled for elective craniotomy for supratentorial brain tumors. However, PVi, being a noninvasive parameter, may be preferable.” They continued, “The two groups in our study were comparable with respect to serum creatinine and serum lactate measured at predetermined time points intraoperatively and post operatively. The two groups were also comparable with respect to brain relaxation scores at dural opening and dural closure. There was moderate to strong correlation between SVV and PVi at corresponding time points intraoperatively. The duration of mechanical ventilation and the length of hospital stay was also comparable between the two groups.”

Joe Kiani, Founder and CEO of Masimo, said, “We introduced PVi in 2007. It was the first and still is the only noninvasive way of measuring fluid responsiveness in mechanically ventilated patients at a fraction of the cost of invasive methods and without risk of invasive procedures to the patient.  Since then, over 100 studies have shown that PVi or PVi in combination with our noninvasive hemoglobin technology, SpHb^®, has made a tremendous contribution to patient care.² This latest study adds to the evidence that PVi can be used to help clinicians manage the fluid levels of their patients without invasive catheters.”

In the U.S., PVi is FDA 510(k) cleared as a noninvasive dynamic indicator of fluid responsiveness in select populations of mechanically ventilated adult patients. Accuracy of PVi in predicting fluid responsiveness is variable and influenced by numerous patient, procedure and device related factors. PVi measures the variation in the plethysmography amplitude but does not provide measurements of stroke volume or cardiac output. Fluid management decisions should be based on a complete assessment of the patient’s condition and should not be based solely on PVi.

New Study Evaluates the Utility of Masimo ORi™ in Reducing Hyperoxemia During Laparoscopic Gastrectomy

Researchers Found That Using ORi with SpO₂ to Help Guide Supplemental Oxygen Delivery Reduced Intraoperative Hyperoxemia 

Neuchatel, Switzerland - February 21, 2023 - Masimo (NASDAQ: MASI) today announced the findings of a prospective, double-blinded, randomized controlled study published in Medicine in which Dr. Jin Hee Ahn and colleagues at the Sungkyunkwan University School of Medicine in Seoul, Korea evaluated the ability of Masimo ORi™ to assist clinicians in guiding supplemental oxygenation during elective laparoscopic gastrectomy surgery. The researchers found that the combination of ORi and standard of care oxygen saturation (SpO₂) monitoring reduced hyperoxemia compared to SpO₂ monitoring alone.¹ 

ORi, available outside the U.S. since 2014, is a noninvasive and continuous parameter intended to provide additional insight into a patient’s oxygen status under supplemental oxygen. Enabled by the multi-wavelength rainbow^® Pulse CO-Oximetry platform, ORi is provided alongside SpO₂ measured by clinically proven Masimo SET^® pulse oximetry.

Noting that the use of supplemental oxygen during general surgery increases the risk of hyperoxemia, the researchers sought to evaluate whether noninvasive, continuous ORi might improve clinicians’ ability to detect hyperoxemia, since SpO₂ monitoring alone cannot monitor beyond 100% saturation, and since arterial blood gas analysis has the disadvantages of being invasive and giving intermittent, delayed results. To test their hypothesis, the researchers randomly allocated 62 adult patients scheduled for elective laparoscopic gastrectomy into two groups, one whose fraction of inspired oxygen (FiO₂) during anesthesia was guided by ORi and SpO₂ monitoring (the ORi-SpO₂ group, n=30), and a control group whose FiO₂ was guided by SpO₂ monitoring alone (the SpO₂ group, n=32). Patients in both groups were monitored with Masimo Radical-7^® Pulse CO-Oximeters^® with rainbow^® sensors. In addition to Masimo ORi and SET^® SpO₂, Masimo PVi^® (pleth variability index) was monitored as part of goal-directed fluid management. 

In the ORi-SpO₂ group, FiO₂ was adjusted to maintain ORi > 0 and < 0.3, which was evaluated every 2 to 3 minutes throughout surgery. In the SpO₂ group, FiO₂ was adjusted to maintain SpO₂ ≥ 98%, similarly evaluated every 2 to 3 minutes. To assess the incidence of hyperoxemia, the clinicians recorded the arterial partial pressure of oxygen (PaO₂), measured using an ABL-90 FLEX Plus blood gas analyzer, before surgical incision and one, two, and three hours after surgical incision. Hyperoxemia was defined as PaO₂ ≥ 100 mmHg and severe hyperoxemia as PaO₂ ≥ 200 mmHg.

The researchers found that one hour after surgical incision, PaO₂ was higher in the SpO₂ group (250.31 ± 57.39 mmHg) than in the ORi-SpO₂ group (170.07 ± 49.39 mmHg) (p < .001), and remained consistently higher in the SpO₂ group than in the ORi-SpO₂ group over time (p = .045). The rate of severe hyperoxemia was higher in the SpO₂ group (84.4%) than in the ORi-SpO₂ group (16.7%) 1 hour after incision (p < .001).

The researchers concluded, “[I]ntraoperative hyperoxemia was reduced when FiO₂ was adjusted based on the combination of SpO₂ and ORi compared with SpO₂ alone in patients undergoing laparoscopic gastrectomy.”

ORi has not yet received FDA clearance and is not available in the United States.

Masimo Centroid^® Receives Innovative Technology Designation from Vizient 

The Vizient Designation, for Masimo’s Wearable, Wireless Patient Position, Orientation, and Activity Sensor, Recognizes Products That Bring Improvements to the Healthcare Industry

Irvine, California - February 15, 2023 - Masimo (NASDAQ: MASI) today announced that Centroid^®, a wearable, wireless patient orientation and activity sensor, has received an Innovative Technology designation from Vizient, Inc., the largest healthcare performance improvement company in the United States. Masimo exhibited Centroid in combination with the Masimo Root^® Patient Monitoring and Connectivity platform at the Vizient Innovative Technology Exchange held in Dallas last October.

Every year, healthcare experts serving on Vizient member-led councils review select products and technologies for their potential to enhance clinical care, patient safety, healthcare worker safety or to improve business operations of healthcare organizations. Innovative Technology designations are awarded to previously contracted products to signal to healthcare providers the impact of these innovations on patient care and business models of healthcare organizations.

Masimo Centroid is designed to help clinicians monitor patient position to avoid hospital-acquired pressure injuries (HAPIs) – which affect nearly 2.5 million patients in the U.S. each year, of whom nearly 60,000 die as a direct result¹ – and can alert clinicians to sudden movements such as fall-like events. In addition, Centroid detects chest movements to continuously provide respiration rate, assisting clinicians with additional data to help them make more informed care decisions. Centroid pairs with Root using Bluetooth^® to track a patient's posture, orientation, and activity, providing the ability to monitor patient position and detect changes in position. The data transmitted by Centroid can be displayed in various formats on Root, giving clinicians multiple ways to assess adherence to protocols regarding tissue stress and to tailor care to the specific needs of each patient. 

In addition, Centroid data can be relayed via the Masimo Hospital Automation™ platform to Patient SafetyNet™, Masimo’s centralized remote patient supplemental monitoring platform, and Replica^®, a mobile application that allows clinicians to view continuous data regardless of location. Moreover, connectivity to the Masimo Hospital Automation platform allows clinicians to automate the charting of patient turns in electronic medical records (EMRs), as well as run reports and analytics, helping to direct resources and drive continuous improvement in turn protocol adherence.

HAPIs are on the rise, occurring in nearly 5% of all hospitalized patients in the U.S.¹ Elderly and critically ill patients are often at highest risk for developing a HAPI, which can lead to further treatments and extended lengths of stay in the hospital. To compound the patient impact associated with these pressure injuries, there is a major economic burden for the hospital as well. Pressure injuries are classified as a hospital-acquired condition (HAC), and the treatment costs associated with HACs are non-reimbursable to the hospital. One pressure injury can quickly add up to tens of thousands of dollars in excess patient care expenses. Many facilities in the US spend millions each year treating these wounds.² Pressure injuries are also a reportable quality metric to CMS.³

According to the National Pressure Injury Advisory Panel (NPIAP), scheduled turning protocols are known to prevent HAPIs, yet most U.S. hospitals still use techniques such as paper wall clocks or egg timers – methods proving to be ineffective and archaic in modern healthcare – to try and optimize this practice.⁴ Staffing issues and competing priorities have strained nurses, and staying on top of when a patient was last turned is difficult without a more sophisticated system – such as Masimo Centroid.

Bilal Muhsin, Chief Operating Officer of Masimo Healthcare, said, “We are honored that Vizient has selected Centroid for its Innovative Technology designation. Centroid takes advantage of our many years of experience developing advanced monitoring technologies, algorithms, and automation solutions to provide a streamlined and powerful way to help hospitals track patient position from moment to moment. Many thanks to the Vizient council for recognizing our commitment to helping improve patient outcomes, reduce the cost of care, and improve life.”

“A product receives this designation when it has a unique quality that differentiates it from its competitors,” said Kelly Flaharty, Vizient Senior Director of Contract Services. “Our member council determined that Centroid met this standard and recognizes its potential to improve quality outcomes.”

Vizient represents a diverse membership that includes academic medical centers, pediatric facilities, community hospitals, integrated health delivery networks and non-acute healthcare providers and represents approximately $130 billion in annual purchasing volume. Through its Innovative Technology Program, Vizient works with member-led councils and task forces to evaluate products for their potential to bring real innovation to healthcare. Vizient may award a contract to products deemed worthy of the Innovative Technology designation outside of the competitive bid cycle.

Masimo Announces the Limited Market Release of Visual Clinical Activity Monitoring (VCAM^™) 

AI-Based Video Analysis System Promotes Hand Hygiene Compliance, Integrates with Masimo Hospital Automation^™ Platform

Irvine, California - January 30, 2023 - Masimo (NASDAQ: MASI) today announced the limited market release of Visual Clinical Activity Monitoring (VCAM^™), a video analysis system that uses artificial intelligence to help facilitate compliance with hospital hand hygiene protocols. VCAM, which integrates seamlessly with the Masimo Hospital Automation^™ platform of solutions, including Masimo Patient SafetyNet^™, Replica^®, and Root^®, is designed to help hospitals and other care facilities optimize protocol adherence, with real-time notifications at the point-of-care about current hand hygiene status and powerful analytics around protocol compliance – with the ultimate goal of helping institutions decrease the incidence of hospital-acquired infections (HAIs).

Hand hygiene is well known to be an important factor in infection control activities, with numerous studies showing that washing one’s hands is the “single most important, simplest, and least expensive means of reducing the prevalence of HAIs and the spread of antimicrobial resistance.”¹ A recently published study conducted across multiple sites over eight years in Finland, for example, found a direct correlation between increased compliance with hand hygiene protocols and decreased incidence of HAIs.² However, in the absence of “active” hand hygiene initiatives – programs, for example, designed to measure and automate compliance – the compliance rate with such protocols rarely exceeds 40% in hospitals and other healthcare institutions.¹ 

Masimo VCAM, powered by Masimo’s expertise in AI-enabled algorithms and based on each facility’s standards, makes it easier for hospitals to optimize staff adherence to hand hygiene protocols by providing notifications on the spot, tracking compliance, and automating reporting. VCAM detects when clinicians are performing hygiene activities, such as washing hands or using an alcohol-based sanitizer, and identifies when they interact with people and objects, as well as when they touch or pick up an object from a potentially unclean surface such as the floor. Immediate notifications about current hygiene status are relayed to individual clinicians on bedside Root monitors and on Replica-equipped smartphones, prompting them, for example, to wash or sanitize their hands when they may have neglected to do so. In turn, VCAM’s rich reporting capabilities provide detailed analysis, such as the rates of clean vs. dirty incidents (which can be filtered by room and by department), helping leadership target opportunities for workflow improvements. 

Vijay Dhar, MD, Chief of Neonatology at Children’s Hospital of Orange County (CHOC), California, said, “We, at CHOC, are eagerly anticipating the deployment of Masimo VCAM, the innovative artificial intelligence (AI) system that can characterize hand hygiene compliance. We hope VCAM will be able to help us to decrease hospital-acquired infections (HAIs), including viral pathogens such as respiratory syncytial virus (RSV), bacterial organisms such as MRSA, and other nosocomial organisms responsible for central line associated blood stream infections (CLABSI), the most common form of nosocomial infection affecting neonates. With Masimo VCAM helping us maintain hand hygiene, we aim to diminish these totally preventable HAIs and improve the safety and wellbeing of our neonates.” 

Joe Kiani, Founder and CEO of Masimo, said, “VCAM adds an important new tool to the growing Masimo ecosystem of Hospital Automation products, building on our experience developing breakthrough algorithms and next-generation connectivity solutions, to help streamline hospitals’ ability to meet compliance goals with as fundamental and critical a task as hand-washing. VCAM aligns with our continued mission to improve patient outcomes, reduce the cost of care, and ultimately, improve life.”

Neuchatel, Switzerland - January 23, 2023 - Masimo (NASDAQ: MASI) today announced the findings of a prospective, single-blinded, randomized controlled study published in the Journal of Anesthesia & Intensive Care Medicine in which Dr. Mona Mohamed Mogahed and colleagues at Tanta University in Tanta, Egypt and The King Fahd General Hospital in Jeddah, Saudi Arabia, sought to evaluate the impact of varying ventilation strategies on the cerebral oxygenation of patients undergoing video-assisted thoracoscopic surgery (VATS). To monitor the variety of physiological parameters needed to undertake such an evaluation, they turned to the multi-modal Masimo Root^® patient monitoring and connectivity platform, which is designed to allow clinicians to streamline their ability to keep track of numerous modalities, simultaneously, using a single, intuitive monitor. The technologies involved included O3^® regional oximetry, capnography with NomoLine^® sampling lines, SedLine^® brain function monitoring, and multiple rainbow^® Pulse CO-Oximetry measurements. Using Root and Masimo monitoring technologies, the researchers were able to determine that maintaining higher end-tidal carbon dioxide (EtCO₂) improved baseline regional cerebral oxygenation (rSO₂), with impacts on early postoperative cognitive function that included improvements in Aldrete scores and mini mental status exam (MMSE) scores.¹ 

Noting the increased risk of hypoxemia during one-lung ventilation (OLV) as part of VATS, which can lead to postoperative neurocognitive dysfunctions, the authors hypothesized that increasing EtCO₂ could be a “convenient and powerful” way to manage cerebral desaturation during the surgery. They enrolled 70 patients, ages 18-65, undergoing elective VATS requiring OLV, between September 2021 and September 2022 at The King Fahd General Hospital, Jeddah. All patients were operated on by the same surgical team. The patients were randomly divided into two groups: in the first, EtCO₂ was maintained at 32-38 mmHg (group I) and in the second, at 39-45 mmHg (group II). During the procedure, monitored parameters included oxygen saturation (Masimo SET^® SpO₂), heart rate (HR), and noninvasive hemoglobin (Masimo SpHb^®) via an RD rainbow SET^® fingertip sensor; EtCO₂ via capnometer and NomoLine sampling line; noninvasive blood pressure (NIBP), body temperature, and rSO₂ via O3 near-infrared spectroscopy (NIRS) sensors monitoring both brain hemispheres; and Masimo Patient State Index (PSi^™), a processed EEG parameter used to help clinicians maintain appropriate sedation, via SedLine. Outcomes included Aldrete scores and MMSE scores assessed at 3 and 24 hours after surgery.

The researchers found that the percentage of change in rSO₂ differed significantly between groups (p < 0.05), on both sides of the brain, with the higher values, over time, in Group II, in direct relation with the higher EtCO₂ maintained in that group. In the right hemisphere, the difference became significant at the fourth time interval [T4] at which rSO₂ was recorded, p = 0.0012, and maintained significance for the remainder of surgery [T4-T13], p < 0.001. In the left hemisphere, the difference became significant at T2, p = 0.09, and remained significant [T3-13], p < 0.001. Aldrete scores were significantly higher in Group II upon arrival at the post-anesthesia care unit (PACU) (p = 0.013) and 15 minutes after arrival (p = 0.03), then became comparable. MMSE scores were significantly higher in Group II 3 hours after surgery (p = 0.0009), but not at 24 hours after surgery.

The researchers concluded, “Adjusting the ventilator parameters to develop EtCO₂ of 39-45 mmHg improved cerebral oxygenation more than EtCO₂ of 32-38 mmHg, that play[s] a protective role in the brain, causing significant impact on the early postoperative cognitive function in patients with OLV undergoing VATS.” Regarding the use of Masimo Root and associated monitoring technologies, they noted that they “preferred using it as it can display several clinical measurements [at] the same time, such as HR, BP, temperature, SpO₂, EtCO₂, PSi, and rSO₂.”

ITC Judge Rules Apple Violated U.S. Trade Laws by Infringing Masimo Pulse Oximeter Patent 

Irvine, California - January 10, 2023 - A United States Administrative Law Judge in Washington, D.C. ruled that Apple Inc. (Nasdaq: AAPL) violated Section 337 of the Tariff Act of 1930 as amended, by importing and selling within the United States certain Apple Watches with light-based pulse oximetry functionality and components, which infringe one of Masimo's (Nasdaq: MASI) pulse oximeter patents. Apple first released its pulse oximeter sensor with the Apple Watch Series 6 in 2020 and continues to use it in the current Apple Watches. The United States International Trade Commission (USITC) will now consider whether to implement a ban on imports of these Apple Watches. 

“We are happy that the ALJ recognized Apple’s infringement of Masimo’s pulse oximetry technology and took this critical first step toward accountability,” said Joe Kiani, CEO of Masimo.  “Today’s decision should help restore fairness in the market. Apple has similarly infringed on other companies’ technologies, and we believe today’s ruling exposes Apple as a company that takes other companies’ innovations and repackages them.”

Masimo is the global leader of pulse oximeters for medical use, having revolutionized the industry with its Masimo SET® pulse oximetry technology, proven to help reduce blindness in babies in the neonatal intensive care unit, save lives of post-surgical patients on opioids and COVID patients monitored remotely. Masimo recently debuted its own watch – the Masimo W1™ – which is the first wearable device on the market to provide consumers with accurate, continuous health data, including oxygen level, hydration index, and pulse, heart, and respiration rates

New Study Evaluates the Performance of Masimo SpHb^® Noninvasive Spot-Check Hemoglobin in the Emergency Department

Masimo SpHb on the Handheld Masimo Rad-67^® Demonstrated “Acceptable Accuracy and Excellent Correlation” with Laboratory Hemoglobin

Neuchatel, Switezerland - January 09, 2022 - Masimo (NASDAQ: MASI) today announced the results of a prospective study published in the American Journal of Emergency Medicine in which Dr. Zohair Ahmed Ali Al Aseri and colleagues at King Saud University Medical City and Dar Al Uloom University (Riyadh, Saudi Arabia) evaluated the performance of noninvasive spot-check hemoglobin measurement with Masimo SpHb^® on emergency department (ED) patients. The researchers found that SpHb provided “acceptable accuracy and excellent correlation” with their invasive laboratory measurements and offers an “easy, quick, feasible, cheap, and accurate solution for Hb measurement in the ED.”¹

Noting that invasive blood hemoglobin measurement, while an important step in the management of blood loss, has drawbacks such as “consumption of valuable time, phlebotomy-induced anemia, pain, infection, and more involvement of human resources and equipment,” the authors sought to evaluate whether a noninvasive modality might offer similarly accurate results while mitigating some of these factors. To compare noninvasive and invasive measurements, they enrolled 650 patients (age > 14 years) who visited the EDs of two hospitals within King Saud University Medical City between March and May 2022 and needed complete blood count measurements. Hemoglobin was noninvasively measured (SpHb) using the Masimo Rad-67^® handheld Pulse CO-Oximeter^® with the DCI^®-mini fingertip sensor. Simultaneously, blood samples were collected and analyzed at the time of collection (LabHb) using their automated analyzer, a UniCel DxH 800 Coulter Cellular Analysis System.

The researchers found a “highly significant correlation” between SpHb and LabHb (Pearson correlation coefficient = 0.812, p < 0.01). Bland-Altman analysis revealed low mean bias of 0.146 g/dL ± 1.39 g/dL, with moderate limits of agreement (-2.58 and 2.87 g/dL) and a margin of error (95% confidence interval) of 2.7 g/dL. 

The researchers concluded that “noninvasive hemoglobin (SpHb) measurement showed acceptable accuracy and excellent correlation with LabHb and provided an easy, quick, feasible, cheap, and accurate solution for Hb measurement in the ED. Further research is required to study its effects on patient outcomes and blood transfusion and time and cost effectiveness.”

SpHb is not intended to replace laboratory blood testing. Clinical decisions regarding red blood cell transfusions should be based on the clinician’s judgment considering, among other factors, patient condition, continuous SpHb monitoring, and laboratory diagnostic tests using blood samples.

New Study Finds That Masimo Patient SafetyNet™ Helped Clinicians Reduce CPR Events and Rates, Improve CPR Success Rate, and Reduce Hospital Length of Stay and Mortality

Neuchatel, Switzerland - January 5, 2023 - Masimo(NASDAQ: MASI) today announced the findings of a before-and-after study published in PLoS ONE in which Dr. Ahmed Balshi and colleagues at King Saud Medical City in Riyadh, Saudi Arabia, evaluated the impact of implementing remote patient monitoring with Masimo Patient SafetyNet™ on the efficacy of hospital rapid response teams (RRTs). Comparing outcomes before and after implementation of Patient SafetyNet, they found that the “after” group experienced more RRT activations but had significantly lower incidence and rate of cardiopulmonary resuscitation (CPR), significantly shorter hospital length of stay (LOS), and lower hospital mortality.¹

Noting that RRT activation depends on the “timely detection of [patient] deterioration,” the researchers sought to determine whether a remote patient surveillance system that automated calculation and relaying of early warning scores could lead to earlier recognition of changes in patient status and the improved efficacy of RRTs. They hypothesized that implementing such a system could decrease the rate of severe adverse events, as a result of potentially quicker RRT activation. To that end, they designed a “before” and “after” study at a large government hospital (1,200 inpatient beds) in central Saudi Arabia where the ICU provides outreach, in the form of an RRT, to the general ward. 

In the “before” period (retrospective data) nurses manually recorded patient vital signs, calculated warning scores, and activated RRTs; in the “after” period” (prospective data), vital signs data collected at the bedside, alongside automatically calculated warning scores, were wirelessly relayed to nursing stations for centralized remote patient surveillance and RRT activation. Both before and after, activation of an RRT was triggered when a patient’s vital signs deteriorated to the point they scored ≥ 5 on the MEWS (Modified Early Warning Score) scale. “Before” group data was analyzed from 2,346 adult patients from January to August 2020, and “after” group data from 2,151 patients from September 2020 to April 2021. For the “after” group, Masimo Patient SafetyNet was used to automate transfer of bedside monitoring data to central nursing stations, with alarm and notification data also relayed to clinicians’ smartphones using Masimo Replica^®.

The researchers found that in the “before” group, there were 78 episodes of CPR over 20,510 total inpatient days, for an incidence of 3.3% and rate of 3.8 per 1000 inpatient days (95% confidence interval: 3 – 4.7 episodes). In the “after” group, there were 42 episodes over 17,945 inpatient days, for an incidence of 1.95% and rate of 2.3 per 1000 inpatient days (95% CI: 1.7 – 3.2). CPR incidence in the “after” group was significantly lower (p = 0.01). In addition, the CPR success rate was significantly higher in the “after” group (before: 38.5% vs. after: 59.5%; p = 0.04). The average hospital LOS was higher in the “before” group (before: 8.7 days ± 3.4 days vs. after: 8.3 days ± 3 days; 95% CI of the difference: 0.2 – 0.6 days; p < 0.001). The number of RRT activations was lower in the “before” group (before: 20 ± 7 vs. after: 23.7 ± 9.4; 95% CI of the difference: 3.2 – 4.2; p < 0.001). Overall hospital mortality was lower in the “after” group (before: 5.45% vs. after: 4%; 95% CI: 0.6 - 2.2; p < 0.001). Using multivariable logistic regression, they calculated that being in the “after” group decreased a patient’s odds of needing CPR by 33% (odds ratio: 0.67; 95% CI: 0.46 – 0.99; p = 0.04).

The investigators concluded, “Automated activation of the RRT by Masimo Patient SafetyNet applied to medical ward patients significantly reduced CPR events and rates, reduced hospital length of stay, and increased the number of RRT activations. There was no difference in the ICU admission rates. Further evaluation of the system in surgical wards and mixed settings [should be] conducted.”

New Prospective Study Evaluates the Accuracy of Masimo SpHb^® Noninvasive and Continuous Hemoglobin Monitoring During Elective Cesarean Section

Masimo SpHb Demonstrated ?Clinically Acceptable Accuracy? of Hemoglobin Measurement, Even at Low Hemoglobin Levels

Neuchatel, Switzerland - January 3, 2023 - Masimo (NASDAQ: MASI) today announced the findings of a prospective study published in the Egyptian Journal of Anesthesia in which Dr. Mohamed Ibrahim Beleta and colleagues at Cairo University evaluated the accuracy of noninvasive, continuous hemoglobin monitoring with Masimo SpHb^® on patients undergoing elective cesarean section (CS) with antepartum hemorrhage. The researchers found significant positive correlations between SpHb and invasive hemoglobin (Hb) values, and concluded, "In patients undergoing CS with antepartum hemorrhage, continuous SpHb through Masimo Pulse CO-Oximetry demonstrated clinically acceptable accuracy of Hb measurement compared with invasive Hb, even at low hemoglobin levels."¹

The authors note that antepartum hemorrhage is associated with adverse maternal and neonatal outcomes and that blood transfusion is also associated with a variety of risks, but that invasive laboratory hemoglobin measurement, while a crucial factor in transfusion decisions, yields intermittent and often delayed results. The researchers thus sought to evaluate whether use of noninvasive, continuous hemoglobin monitoring might ?enable a more rapid detection of clinically significant blood loss, improve perioperative transfusion practices, allow patient condition to be assessed more quickly and blood management more adequately, and perhaps even reduce needless transfusions.? They enrolled 60 pregnant women, aged 18-45, scheduled for elective CS under general anesthesia between April 2016 and December 2017. All subjects had antepartum hemorrhage and were candidates for blood transfusion. During the procedure, all patients were monitored as per hospital standards, and in addition, with Masimo SpHb. All blood samples (Lab Hb) were analyzed using the same Coulter laboratory analyzer to avoid variance induced by the use of multiple devices. Lab Hb and SpHb values were recorded before induction of anesthesia (baseline), before transfusion, and after transfusion. Blood transfusion was carried out when Lab Hb decreased by more than 20% from baseline.

The researchers found significant positive correlations between SpHb and invasive Hb at the three points of comparison: baseline (r = 0.946), pre-transfusion (r = 0.902), and post-transfusion (r = 0.698). Differences at those times were insignificant: p = 0.196, p = 0.092, and p = 0.570, respectively. Using Bland-Altman analysis, they found low bias and moderate limits of agreement: 0.348 g/dL (-0.584 and 1.280) at baseline measurement, 0.314 g/dL (-0.561 and 1.188) at pre-transfusion, and 0.348 g/dL (-0.584 and 1.280) at post-transfusion.

The investigators concluded, "Continuous SpHb Masimo Pulse CO-Oximetry shows an appropriate clinically reliable Hb calculation in comparison to Invasive Hb even in patients undergoing CS with low hemoglobin. Further studies are needed on larger sample size with multicenter collaboration. Furthermore, we recommend the assessment of this technique on patients with common morbidities, such as high cholesterol, high blood pressure, and diabetes."

The researchers also noted that "SpHb evaluation has the potential for additional benefits, including patient comfort, increased safety, and decreased complexity for healthcare staff, who are not exposed to the risks of needle-stick injury and bloodspill contamination."

SpHb is not intended to replace laboratory blood testing. Clinical decisions regarding red blood cell transfusions should be based on the clinician's judgment considering, among other factors, patient condition, continuous SpHb monitoring, and laboratory diagnostic tests using blood samples.
