Masimo Announces Desaturation Index 3D Alarm as Standard Feature in All Radical-7 Pulse CO-Oximetry Devices

IRVINE, Calif., Sept. 10 (HSMN NewsFeed) -- Masimo (Nasdaq: MASI ), the inventor of Pulse CO-Oximetry and Measure-Through-Motion-and-Low-Perfusion pulse oximetry, today announced that all customers purchasing the Masimo Radical-7, the company's flagship product, will now receive Desat Index 3D Alarm as a standard feature.

Conventional Pulse Oximeters typically alarm based on large and isolated drops in oxygen saturation values, known as a "desaturation". However, published research has shown that a cycle of moderate desaturations has been shown to precede respiratory failure in hospitalized patients(1,2). Masimo Desat Index 3D Alarm enables advanced notification of these conditions, based on clinician-specified severity and number of desaturations occurring in a specified period of time.

Michael O'Reilly, MD, Masimo Executive Vice President of Medical Affairs, stated; "When combined with the proven ability of Masimo Signal Extraction Technology (SET) to dramatically reduce false desaturation alarms and improve the detection of true desaturations, Masimo Desat Index 3D Alarm advances patient care by allowing earlier intervention to prevent adverse respiratory events."

Joe Kiani, Chairman and CEO of Masimo, stated; "Masimo has been selling Desat Index 3D Alarm as an option for almost three years. In light of our soon-to-be released breakthrough innovation, noninvasive and continuous hemoglobin monitoring technology, we are pleased to now offer Desat Index 3D Alarm as a standard feature."

About Masimo

Masimo (NASDAQ: MASI ) develops innovative monitoring technologies that significantly improve patient care-helping solve "unsolvable" problems. In 1995, the company debuted Measure-Through-Motion-and-Low-Perfusion pulse oximetry, known as Masimo SET, which virtually eliminated false alarms and increased pulse oximetry's ability to detect life-threatening events. More than 100 independent and objective studies demonstrate 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 Masimo Rainbow SET, a breakthrough noninvasive blood constituent monitoring platform that can measure many blood constituents that previously required invasive procedures. Masimo Rainbow SET continuously and noninvasively measures total hemoglobin (SpHb(TM)), oxygen content (SpOC(TM)), carboxyhemoglobin (SpCO®), methemoglobin (SpMet®), and PVI(TM), in addition to oxyhemoglobin (SpO2), pulse rate (PR), and perfusion index (PI), allowing early detection and treatment of potentially life-threatening conditions. Founded in 1989, Masimo has the mission of "Improving Patient Outcomes and Reducing Cost of Care by Taking Noninvasive Monitoring to New Sites and Applications."
