When providing perioperative care, clinicians may benefit from continuous monitoring of key physiologic measurements and intuitive centralized displays of real-time patient data. Masimo offers multiple advanced noninvasive and continuous monitoring technologies, available on a single integrated platform and on select third-party multi-parameter monitors.

Masimo's breakthrough Signal Extraction Technology® (SET®) overcomes the limitations of conventional pulse oximetry with the ability to measure through motion and low perfusion.

Masimo rainbow SET™ technology, which leverages multiple additional wavelengths of light, is a suite of noninvasive measurements including total hemoglobin (SpHb®) and dyshemoglobins. The rainbow SET technology platform also uniquely offers Pleth Variability Index (PVi®), a noninvasive dynamic measurement of changes in perfusion index.

With measurement innovation at its core, Masimo has continued to expand its monitoring technologies to include brain function monitoring and cerebral oximetry. Masimo’s Next Generation SedLine® brain function monitoring features an enhanced signal processing engine, driving a variety of performance improvements, with processing of four leads of bilateral EEG. O3® regional oximetry may help clinicians monitor cerebral oxygenation in situations in which peripheral pulse oximetry alone may not be fully indicative of the oxygen in the brain. When used together, Next Generation SedLine and O3 provide a more complete picture of the brain.

These monitoring solutions are available on the Root® patient monitoring and connectivity platform, as well as on select third-party multi-parameter monitors. Root’s plug-and-play expansion capabilities allow clinicians to centralize patient monitoring by bringing together rainbow SET Pulse CO-Oximetry, Next Generation SedLine brain function monitoring, and O3 regional oximetry on an easy-to-interpret, customizable display, providing clinicians with more information for patient assessment.

Total Hemoglobin – SpHb

Noninvasive and continuous SpHb provides real-time visibility to changes, or lack of changes, in hemoglobin between invasive blood samples

Masimo - SpHb Chart - PLM-10283B

SpHb trend monitoring may provide additional insight between invasive blood samples when:

  • The SpHb trend is stable and the clinician may otherwise think hemoglobin is dropping
  • The SpHb trend is rising and the clinician may otherwise think hemoglobin is not rising fast enough
  • The SpHb trend is dropping and the clinician may otherwise think hemoglobin is stable

Pleth Variability Index – PVi

An automatic measurement of the dynamic changes in Perfusion Index (Pi) that occur during one or more respiratory cycles

  • PVi may show changes that reflect physiologic factors such as vascular tone, circulating blood volume, and intrathoracic pressure excursions
Masimo - SedLine Digital One Up

Next Generation SedLine features an enhanced signal processing engine, driving a variety of performance improvements, and an enhanced Multitaper Density Spectral Array (DSA).

Next Generation SedLine provides a more complete picture of the brain with:

  • Four simultaneous channels of frontal EEG waveforms
  • An enhanced Patient State Index (PSi), a processed EEG parameter that is related to the effect of anesthetic agents
  • A DSA display, which contains left and right spectrograms representing the power of the EEG on both sides of the brain
  • A Multitaper DSA display, which may improve visibility of EEG features
Masimo - O3 Intubated Regional Oximetry

O3 Regional Oximetry uses near-infrared spectroscopy (NIRS) to enable monitoring of cerebral tissue oxygen saturation (rSO2)

  • Helps clinicians monitor cerebral oxygenation in situations in which pulse oximetry alone may not be fully indicative of the oxygen in the brain
  • Seamlessly integrates with the Root platform alongside SedLine brain function monitoring for a more complete brain monitoring solution
Masimo - Kite Image Display

Kite® Supplemental Display

Kite expands visibility of patient data on Root via a supplemental display 

  • The expanded, customizable display allows multiple clinicians to view patient data simultaneously, even in a crowded environment, which may reduce errors caused by miscommunication
  • By customizing what is displayed, Kite allows clinicians to focus on the most pertinent data for each stage of a patient’s care, empowering clinicians to make more informed decisions
