Masimo

Masimo is a global medical technology company founded in 1989 by engineer Joe Kiani that develops noninvasive patient monitoring technologies. Its work spans adaptive signal processing, pulse oximetry, noninvasive blood constituent monitoring, brain function monitoring, capnography, patient monitoring and connectivity platforms, remote patient monitoring and consumer health wearables.

The company's foundational product is Masimo SET Measure-through Motion and Low Perfusion pulse oximetry, introduced in 1995. Using adaptive signal processing, it provides readings during patient motion and low perfusion conditions. It is now the primary pulse oximetry technology in 9 of the top 10 U.S. hospitals. Other products include rainbow Pulse CO-Oximetry for noninvasive blood constituent monitoring, SedLine for brain function monitoring, capnography solutions, and Root, a patient monitoring and connectivity platform. Masimo also extends its monitoring technology beyond the hospital with SafetyNet, a remote monitoring system for home care, and the Masimo W1 consumer health watch.

Masimo reports monitoring more than 200 million patients globally each year and operates across the United States and worldwide. Its work covers the hospital, home care and consumer healthcare settings.

The company describes its culture as mission-driven, focused on solving clinical problems considered unsolvable and on improving patient care while reducing healthcare costs. Its stated direction is to extend noninvasive monitoring to new sites and applications, from hospital wards to home care.
