Masimo (Nasdaq: MASI) is a global leader in innovative noninvasive monitoring technologies. Our mission is to improve patient outcomes and reduce the cost of care by taking noninvasive monitoring to new sites and applications. In 1995, the company debuted Masimo SET Measure-through Motion and Low Perfusion pulse oximetry, which has been shown in multiple studies to significantly reduce false alarms and accurately monitor for true alarms. Masimo SET is estimated to be used on more than 100 million patients in leading hospitals and other healthcare settings around the world. In 2005, Masimo introduced rainbow Pulse CO-Oximetry technology, allowing noninvasive and continuous monitoring of blood constituents that previously could only be measured invasively, including total hemoglobin (SpHb ), oxygen content (SpOC ), carboxyhemoglobin (SpCO ), methemoglobin (SpMet ), and more recently, Pleth Variability Index (PVI ) and Oxygen Reserve Index (ORI ), in addition to SpO2, pulse rate and perfusion index (PI). In 2014, Masimo introduced Root , an intuitive patient monitoring and connectivity platform with the Masimo Open Connect (MOC-9 ) interface. Masimo is also taking an active leadership role in mHealth with products such as the Radius-7 wearable patient monitor and the MightySat fingertip pulse oximeter.
