Masimo is a global medical technology company that develops and manufactures innovative noninvasive patient monitoring technologies, including medical devices and a wide array of sensors. A key medical technology innovator, Masimo is responsible for the invention of award-winning noninvasive technologies that are revolutionizing patient monitoring, including Masimo SET® pulse oximetry, Masimo rainbow® SET Pulse CO-Oximetry and new Masimo noninvasive and continuous total hemoglobin (SpHb®) monitoring technology. These new rainbow® technologies are expected to open new markets and significantly expand the company’s growth opportunities. Joe Kiani founded Masimo in 1989 as a private "garage start-up" company because he was convinced that the use of adaptive signal processing in the measurement of physiological parameters could solve the problems of low perfusion and motion, which had long plagued in-vivo monitoring and especially pulse oximetry.

Today, Masimo has grown into a successful publicly traded medical technology company employing over 2,500 people worldwide with product revenues that have increased 4-fold in the last five years. In addition, the company has technology license and OEM agreements with leading patient monitoring manufacturers spanning the globe including Atom, Datascope, GE Medical, Medtronic, Philips, Spacelabs, and Zoll. Masimo is not only the inventor of Measure-through Motion and Low Perfusion pulse oximetry and Pulse CO-Oximetry technologies, but is also the market-leading pulse oximetry technology solution.

In 1995, Masimo debuted Measure-through Motion and Low Perfusion pulse oximetry, known as Masimo SET—a breakthrough in pulse oximetry technology that virtually eliminated false alarms and increased pulse oximetry’s ability to detect life-threatening events. More than 100 independent and objective studies demonstrate that Masimo SET provides the most reliable SpO2 and pulse rate measurements even under the most challenging clinical conditions, including patient motion and low peripheral perfusion.

In 2005, Masimo introduced rainbow® SET Pulse CO-Oximetry, a breakthrough noninvasive blood constituent monitoring platform that measures many blood constituents that previously required invasive procedures. Masimo rainbow SET continuously and noninvasively measures total hemoglobin (SpHb®), oxygen content (SpOC™), carboxyhemoglobin (SpCO®), methemoglobin (SpMet®) and pleth variability index (PVI®), in addition to oxyhemoglobin (SpO2), pulse rate (PR), and perfusion index (PI), enabling early detection and treatment of potentially life-threatening conditions.

For more than 20 years now, Masimo has been focused on a singular mission to create noninvasive patient monitoring technologies that are more effective and reliable and to improve patient outcomes and reduce the cost of care by bringing these technologies to new sites and applications. The result is a portfolio of clinically-proven products that lead the way in innovation, performance and patient safety by giving health care providers the information they need to optimize clinical decision-making.
