U.S. Medical Materiel Enterprise Standardization Office Selects Masimo Rad-57(TM) Handheld Pulse CO-Oximeter as Joint Product of Choice

July 3, 2012
Rad-57s Available to All Branches of Military Medical Treatment Facilities and Field Units

IRVINE, Calif., July 3, 2012 /PRNewswire via COMTEX/ -- The U.S. Department of Defense Military Health System has selected the Masimo Rad-57(TM) Handheld Pulse CO-Oximeter as the military's standardized handheld pulse oximeter for use worldwide, Masimo (NASDAQ: MASI) announced today. This agreement is available to all designated Medical Treatment Facilities and Operational Field Units across the Department of Defense's global healthcare system, from first responders to definitive care.

The Defense Department selected the Rad-57 after product evaluations at 13 Medical Treatment Facilities worldwide and an extensive Joint Product Review Board selection process. The Rad-57 has already secured Air Worthiness Certification from the U.S. Army and Safe-to-Fly Certification from the U.S. Air Force.

The department initially will use the Rad-57 to measure oxygen saturation (SpO2) using Masimo SET® Measure-through Motion and Low Perfusion pulse oximetry clinically proven in more than 100 independent and objective studies to provide accurate measurements even under the most challenging conditions. The Rad-57 also features Masimo rainbow® Pulse CO-Oximetry(TM), allowing clinicians to noninvasively monitor multiple blood constituents that previously required invasive or complicated procedures, including total hemoglobin (SpHb®), oxygen content (SpOC(TM)), carboxyhemoglobin (SpCO®), methemoglobin (SpMet®), Pleth Variability Index (PVI®), and perfusion index (PI). Masimo rainbow® SET measurements are available with a simple software upgrade that the user may purchase at any time for the Rad-57.

Joe Kiani, Masimo CEO and Chairman of the Board, said, "The best place for our soldiers to be is safe at home. But when they are in harm's way, we want to be there for them. We are honored our life-saving technology will be with them to help them come home."

About Masimo
Masimo (NASDAQ: MASI) is the global leader in innovative noninvasive 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 rainbow SET® Pulse CO-Oximetry(TM) technology, allowing noninvasive and continuous monitoring of blood constituents that previously required invasive procedures, including total hemoglobin (SpHb®), oxygen content (SpOCTM), carboxyhemoglobin (SpCO®), methemoglobin (SpMet®), and Pleth Variability Index (PVI®), in addition to SpO2, pulse rate, and perfusion index (PI). In 2008, the company introduced Masimo SafetyNet(TM), a remote monitoring and wireless clinician notification system designed to help hospitals avoid preventable deaths and injuries associated with failure to rescue events. In 2009, Masimo introduced rainbow Acoustic Monitoring(TM), the first-ever noninvasive and continuous monitoring of acoustic respiration rate (RRa(TM)). Masimo's rainbow SET technology platform offers a breakthrough in patient safety by helping clinicians detect life-threatening conditions and helping guide treatment options. In 2010, Masimo acquired SEDLine®, a pioneer in the development of innovative brain function monitoring technology and devices. Masimo SET and Masimo rainbow SET technologies can also be found in over 100 multiparameter patient monitors from over 50 medical device manufacturers around the world. Founded in 1989, Masimo has the mission of "Improving Patient Outcome and Reducing Cost of Care ... by Taking Noninvasive Monitoring to New Sites and Applications®."
