The Birth of Masimo: How Project Stork and SET® Pulse Oximetry Revolutionized Neonatal Care

About Masimo

Masimo is a global medical technology company that develops and produces a wide array of industry-leading monitoring technologies, including innovative measurements, sensors, patient monitors, and connectivity solutions. In 1995, Masimo debuted SET® Measure-through Motion and Low Perfusion™ pulse oximetry, estimated to be used on more than 100 million patients annually. In 2005, Masimo introduced rainbow® Pulse CO-Oximetry, allowing noninvasive and continuous monitoring of additional physiologic parameters that previously could only be measured invasively, such as total hemoglobin (SpHb®). We continue to advance noninvasive monitoring, connectivity, and automation with innovations like the Root® patient monitoring and connectivity hub and the Patient SafetyNet™ supplemental remote monitoring solution.
