About Masimo

Masimo (Nasdaq: MASI) develops innovative monitoring technologies that significantly improve patient care-helping solve "unsolvable" problems. In 1995, the company debuted Read-Through Motion and Low Perfusion pulse oximetry, known as Masimo SET, and with it virtually eliminated false alarms and increased pulse oximetry's ability to detect life-threatening events. More than 100 independent and objective studies have confirmed that Masimo SET technology allows clinicians to accurately monitor blood oxygen saturation in critical care situations. Our Masimo SET platform has significantly addressed many of the previous technology limitations, has substantially contributed to improved patient outcomes and has been referred to by several industry sources as the gold standard in pulse oximetry. In 2005, Masimo introduced Masimo Rainbow SET Pulse CO-Oximetry, which, for the first time, noninvasively monitors the level of carbon monoxide and methemoglobin in the blood, allowing early detection and treatment of potentially life-threatening conditions. Founded in 1989, Masimo has the mission of "Improving Patient Outcomes and Reducing Cost of Care by Taking Noninvasive Monitoring to New Sites and Applications."
