The History of Masimo SET® Pulse Oximetry

 

Masimo (NASDAQ: MASI) is a global medical technology company that develops and manufactures innovative noninvasive patient monitoring technologies, medical devices, and a wide array of sensors. We believe that Masimo SET® helps clinicians monitor in excess of approximately 100 million patients in healthcare settings around the world,1 and is the primary pulse oximetry technology at 17 of the top 20 hospitals listed in the 2017-2018 U.S. News & World Report Best Hospitals Honor Roll.2

Joe Kiani founded Masimo in 1989 as a private "garage start-up" company because he was convinced that the use of adaptive signal processing in the measurement of physiological parameters could solve the problems of low perfusion and motion, which had long plagued in-vivo monitoring and especially pulse oximetry, the measurement of the oxygen saturation of arterial blood. His solution, Masimo SET® Measure-through Motion* and Low Perfusion pulse oximetry, was shown in a study comparing three pulse oximetry technologies to demonstrate the highest sensitivity and specificity in identifying desaturation events during conditions of motion and low perfusion.3

Masimo Today

 

Today, Masimo is publicly traded and employs over 4,600 people worldwide, with annual revenues of approximately $800 million (USD).  Licensing agreements allow Masimo technology to work inside monitoring devices from a host of manufacturers, including Philips, Atom, Mindray North America, GE Medical, Spacelabs, and Zoll. Throughout its more than 25-year journey, Masimo’s mission – to improve patient outcomes and reduce the cost of care – has remained strong. 

Masimo rainbow® Technology

 

rainbow®, introduced in 2005, allows additional parameters to be noninvasively and continuously monitored. Advanced signal processing algorithms and unique adaptive filters work together to isolate, identify, and quantify various types of haemoglobin.

Versatile Devices

 

Masimo SET® and rainbow® technologies, collectively known as rainbow SET, fuel medical monitoring devices such as Root®, Radical-7®, Radius-7®, Rad-97™, and Rad-67™ as well as a multitude of sensors, including the RD collection. These highly versatile monitors are configurable for use in a variety of high- and low-acuity hospital settings, from ICUs and surgical suites to post-operative floors, as well as in long-term care facilities and in the case of Rad-97, for home use.

Complementing devices that primarily monitor continuously, Masimo spot-check devices such as Rad-67, Pronto®, MightySat™ Rx, and iSpO2® Rx allow physician offices, EMS responders, and others to measure oxygen saturation and other valuable measurements. MightySat is also available for personal use for general health and wellness applications.

Expanding Monitoring with Root

 

Masimo continues to expand what can be monitored and how. Root, for example, was built from the ground up to be as flexible and expandable as possible, with Iris® ports and Masimo Open Connect® (MOC-9®) to facilitate the addition of other Masimo and third-party monitoring technologies. Key Masimo additions include:

Next Generation SedLine® Brain Function Monitoring

SedLine helps clinicians monitor the state of the brain under anaesthesia with bilateral data acquisition and processing of four leads of electroencephalogram (EEG) signals. Next Generation SedLine brain function monitoring features an enhanced processed EEG index (PSi, a processed EEG parameter related to the effect of anaesthetic agents) with less susceptibility to EMG interference and improved performance in low power EEG cases.

O3® Regional Oximetry

O3 may help clinicians monitor cerebral oxygenation in situations in which pulse oximetry alone may not be fully indicative of the oxygen in the brain.

Noninvasive Blood Pressure and Temperature

Integrated noninvasive blood pressure and temperature measurements, combined with Root's advanced connectivity, automate vital sign documentation in hospital electronic medical records (EMRs). Rad-97 is similarly available in a configuration with integrated noninvasive blood pressure.

NomoLine™ Capnography Solutions

ISA™ capnography with sidestream CO2 and gas monitoring features NomoLine technology for extended monitoring and cost-effective consumables.

Early Warning Scores

Integrated Early Warning Scores (EWS) help to simplify workflows with automatic, device-based calculations using up to 14 Root-measured and manually entered contributors. EWS protocols can be customized based on hospital protocol. Root's ability to display EWS trends allows clinicians to quickly visualize changes in patient status over time, and automated electronic charting allows them to push EWS calculations to hospital EMRs at the touch of a button.

Vital Signs Check

Vital Signs Check on Root helps clinicians streamline vital signs workflows by automating clinician-patient and patient-data association at the bedside; centralizing the collection of both integrated measurement and manually entered data, including early warning scores, on a single device; and facilitating immediate electronic charting from the bedside, with the ability to send comprehensive spot-check data to the EMR at the touch of a button and to store up to 1,000 spot-check sessions with unique patient identifiers locally.

Connecting Devices and Data, Patients and Clinicians

 

Joining the expanding set of monitoring possibilities are redefined and extended connectivity and automation solutions. Masimo Iris Gateway™ gathers medical data from devices throughout the hospital, including ADT systems, and converts and transfers them to a central repository, the EMR, thus automating clinician access to a more complete picture of each patient. To those abilities, Masimo Patient SafetyNet™** with Replica™ adds hospital-wide monitoring and two-way remote clinician notification from a central server, customisable view stations, and mobile devices. The wearable Masimo Radius-7 allows for the tetherless monitoring of mobile patients, communicating alarms wirelessly back to Root and Patient SafetyNet.
