GE HealthCare and Masimo Collaborate to Bring Masimo SET® Pulse Oximetry to the Wireless and Wearable GE HealthCare Portrait Mobile Platform

Masimo (NASDAQ: MASI) is a global medical technology company that develops and produces a wide array of industry-leading monitoring technologies, including innovative measurements, sensors, patient monitors, and automation and connectivity solutions. In addition, Masimo Consumer Audio is home to eight legendary audio brands, including Bowers & Wilkins, Denon, Marantz, and Polk Audio. Our mission is to improve life, improve patient outcomes, and reduce the cost of care. Masimo SET^® Measure-through Motion and Low Perfusion^™ pulse oximetry, introduced in 1995, has been shown in over 100 independent and objective studies to outperform other pulse oximetry technologies.2 Masimo SET^® has also been shown to help clinicians reduce severe retinopathy of prematurity in neonates,7 improve CCHD screening in newborns,8 and, when used for continuous monitoring with Masimo Patient SafetyNet^™ in post-surgical wards, reduce rapid response team activations, ICU transfers, and costs.3-6 Masimo SET^® is estimated to be used on more than 200 million patients in leading hospitals and other healthcare settings around the world,9 and is the primary pulse oximetry at 9 of the top 10 hospitals as ranked in the 2022-23 U.S. News and World Report Best Hospitals Honor Roll.10 In 2005, Masimo introduced rainbow^® Pulse CO-Oximetry technology, allowing noninvasive and continuous monitoring of blood constituents that previously could only be measured invasively, including total hemoglobin (SpHb^®), oxygen content (SpOC^™), carboxyhemoglobin (SpCO^®), methemoglobin (SpMet^®), Pleth Variability Index (PVi^®), RPVi^™ (rainbow^® PVi), and Oxygen Reserve Index (ORi^™). In 2013, Masimo introduced the Root^® Patient Monitoring and Connectivity Platform, built from the ground up to be as flexible and expandable as possible to facilitate the addition of other Masimo and third-party monitoring technologies; key Masimo additions include Next Generation SedLine^® Brain Function Monitoring, O3^® Regional Oximetry, and ISA^™ Capnography with NomoLine^® sampling lines. Masimo’s family of continuous and spot-check monitoring Pulse CO-Oximeters^® includes devices designed for use in a variety of clinical and non-clinical scenarios, including tetherless, wearable technology, such as Radius-7^®, Radius PPG^®, and Radius VSM^™, portable devices like Rad-67^®, fingertip pulse oximeters like MightySat^® Rx, and devices available for use both in the hospital and at home, such as Rad-97^®. Masimo hospital and home automation and connectivity solutions are centered around the Masimo Hospital Automation^™ platform, and include Iris^® Gateway, iSirona^™, Patient SafetyNet, Replica^®, Halo ION^®, UniView^®, UniView :60^™, and Masimo SafetyNet^®. Its growing portfolio of health and wellness solutions includes Radius T°^® and the Masimo W1^™ watch. Additional information about Masimo and its products may be found at www.masimo.com.
