In 1989, engineer Joe Kiani founded Masimo with a vision to solve what seemed like an unsolvable problem: accurate pulse oximetry during patient motion and low perfusion conditions. Working from a garage startup, Kiani was convinced that adaptive signal processing could revolutionize patient monitoring. His breakthrough invention, Masimo SET Measure-through Motion and Low Perfusion pulse oximetry, introduced in 1995, would become the industry standard trusted by clinicians worldwide and is now the primary pulse oximetry technology in 9 of the top 10 U.S. hospitals.
Today, Masimo has evolved into a global medical technology powerhouse that empowers clinicians with breakthrough monitoring technologies designed to improve patient care and reduce costs. The company's innovative portfolio extends far beyond pulse oximetry to include rainbow Pulse CO-Oximetry for noninvasive blood constituent monitoring, brain function monitoring with SedLine, capnography solutions, and the Root patient monitoring and connectivity platform. Masimo's mission to take noninvasive monitoring to new sites and applications has driven expansion into consumer healthcare with products like the Masimo W1 health watch and SafetyNet remote monitoring system. Used to monitor more than 200 million patients globally each year, Masimo continues to push the boundaries of what noninvasive monitoring can achieve, from hospital wards to home care settings.
