Masimo Noninvasive and Continuous Hemoglobin Receives Market Clearance in Japan

September 15, 2010

IRVINE, Calif., Sept 15, 2010 /PRNewswire via COMTEX/ --

Masimo (Nasdaq: MASI) announced today the Japanese Ministry of Health, Labor and Welfare (MHLW) regulatory clearance of its noninvasive and continuous hemoglobin (SpHb) measurement, available as part of the Masimo rainbow SET(R) platform. Representing a breakthrough solution for noninvasively and continuously measuring a patient's hemoglobin level in real-time, SpHb tracks and trends hemoglobin levels without needles, time-consuming laboratory analysis, and risk of contamination associated with traditional blood tests.

The availability of noninvasive, continuous, and immediate hemoglobin measurements is expected to have wide-ranging clinical impact in Japan--from surgery and intensive care units to less acute care settings, including the emergency department and physician offices. SpHb may help clinicians determine whether a patient has a low hemoglobin level (known as anemia) and facilitate prompt detection of internal bleeding and more appropriate administration of blood transfusions--by referring to the SpHb measurement that is continuously displayed on Masimo rainbow SET Pulse CO-Oximeters(TM).

Now, clinicians in Japan can benefit from the full range of physiologic measurements available on the Masimo rainbow SET platform--including total hemoglobin (SpHb(R)), oxygen content (SpOC(TM)), carboxyhemoglobin (SpCO(R)), methemoglobin (SpMet(R)), Pleth Variability Index (PVI(R)), and acoustic respiration rate (RRa(TM)), in addition to the 'gold-standard' Measure-Through Motion and Low Perfusion performance of Masimo SET(R) oxyhemoglobin (SpO2), perfusion index (PI), and pulse rate (PR).

Joe Kiani, Masimo Founder and CEO, stated, "Receiving full MHLW regulatory approvals for SpHb makes the noninvasive, continuous measurement of hemoglobin universally available to Japanese clinicians. This arms clinicians throughout Japan with the real-time assessment of hemoglobin--enabling more appropriate management of patients both inside and outside of the operating room."

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(R), 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(R) Pulse CO-Oximetry(TM), allowing noninvasive and continuous monitoring of blood constituents that previously required invasive procedures, including total hemoglobin (SpHb(R)), oxygen content (SpOC(TM)), carboxyhemoglobin (SpCO(R)), methemoglobin (SpMet(R)), and Pleth Variability Index (PVI(R)), in addition to SpO2, pulse rate, and perfusion index (PI). In 2009, Masimo introduced rainbow Acoustic Monitoring(TM), the first-ever noninvasive and continuous monitoring of acoustic respiration rate (RRa(TM)). Masimo's rainbow platform offers a breakthrough in patient safety by helping clinicians detect life-threatening conditions and helping guide treatment options. 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(R)."
