Advocate Health Care Renews Multi-Year, System-Wide Contract for Masimo SET(R) Pulse Oximetry Technology

November 23, 2009

IRVINE, Calif., Nov. 23 /PRNewswire-FirstCall/ -- Masimo (Nasdaq: MASI), the inventor of Pulse CO-Oximetry(TM) and Measure-Through Motion and Low-Perfusion pulse oximetry, announced today that Advocate Health Care--Illinois' largest health care provider--has renewed its multi-year, system-wide contract for Masimo SET pulse oximetry technology. A Masimo customer since 2001, Advocate Health Care's renewal of its Masimo SET technology standardization contract means Masimo will continue to support the pulse oximetry needs of more than 200 Advocate sites of care across metropolitan Chicago.

Masimo SET pulse oximetry technology allows hospitals and other care sites to leverage the superior Measure-Through Motion and Low-Perfusion benefits of Masimo SET pulse oximetry, along with the unique breakthrough noninvasive blood constituent monitoring capabilities of Masimo Rainbow SET Pulse CO-Oximetry. Masimo Rainbow SET is the first-and-only technology platform capable of continuously and noninvasively measuring multiple blood constituents that previously required invasive procedures, including: total hemoglobin (SpHb(TM)), oxygen content (SpOC(TM)), carboxyhemoglobin (SpCO®), methemoglobin (SpMet®), and PVI®, in addition to oxyhemoglobin (SpO2), pulse rate (PR), and perfusion index (PI). The ability to immediately detect and treat potentially life-threatening conditions--without having to draw blood and wait for the results--enables earlier and better clinical decisions that may help save lives and improve patient outcomes.

"Advocate Health Care's healing mission calls us to work with partners that share our commitment to our patients' health and safety," said Paul Hoffmann, R.R.T., chairman of the Advocate Health Care respiratory care council. "We are very satisfied with the features and functionality of the Masimo pulse oximetry technology, and we are pleased to continue our relationship with Masimo."

Masimo Founder and CEO, Joe E. Kiani, stated, "Advocate Health is one of the premier health care institutions in the US. We are proud to have earned Advocate's trust over the last eight years and that they have decided to place their trust, business, and pulse oximetry needs in our hands for many more years."

Advocate Health Care, one of the nation's top 10 health systems based on clinical performance, is the largest health care provider in Illinois. As a not-for-profit, mission-based health system, Advocate operates more than 200 sites of care across metropolitan Chicago, including nine acute care hospitals, two children's hospitals, four Level I trauma centers (the state's highest designation in trauma care), a home health care company and one of the region's largest medical groups.

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 SpO(2) 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® Pulse CO-Oximetry(TM), 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."
