Incorporated on May 2, 1989 as a garage startup dedicated to solving the “unsolvable” problem of inaccurate and unreliable conventional pulse oximetry under real-life conditions such as patient movement, Masimo and its breakthrough Measure-through Motion and Low Perfusion SET pulse oximetry today touch hundreds of millions of lives around the world each year.¹ SET pulse oximetry has been shown in more than 100 independent studies to outperform other pulse oximetry technologies,² and is the only pulse oximetry shown in numerous large studies – involving more than 300,000 infants – to improve critical congenital heart disease (CCHD) screening in newborns.^3-13 SET pulse oximetry has also been shown to improve outcomes for patients on opioids in post-surgical wards,^14-17 reduce eye damage and blindness in the neonatal intensive care unit,¹⁸ and reduce mortality among Covid patients remotely monitored at home.¹⁹ Through Masimo’s continued focus on innovation and improvement, SET has evolved to feature the industry’s highest accuracy specifications, on the new RD line of patient sensors; become tetherless, with the secure Bluetooth-equipped continuous Radius PPG; and now, as the foundational technology driving the W1, has become a truly lifestyle-friendly technology for consumers outside hospitals.
