Apria Healthcare Chooses Masimo SET Pulse Oximetry for Use in the Company's Home Health Care Business

August 22, 2007

Ability of Masimo SET pulse oximetry technology to significantly reduce false alarms without missing true hypoxic events cited as the reason for choosing Masimo over all other technologies

IRVINE, Calif., Aug. 22 /PRNewswire-FirstCall/ -- Masimo (Nasdaq: MASI), the inventor of Pulse CO-Oximetry and Read-Through Motion and Low Perfusion pulse oximetry, today announced a partnership with Apria Healthcare to provide pulse oximetry products and accessories for Apria's home health care business. Apria Healthcare is America's leading provider of integrated home health care products and services, offering a comprehensive range of home respiratory therapy, diabetic supplies, medications and equipment, home infusion therapy and home medical equipment services.

Apria conducted a competitive bid in which Masimo was selected due to the superior clinical performance of its proprietary Masimo SET pulse oximetry technology, which significantly enhances the ability of Apria's customers to detect hypoxic events in the home care setting. This will provide patients and caregivers with reliable warnings of these instances where blood oxygen levels begin to drop, which in turn will lead to expedient intervention and the delivery of the appropriate level of care.

Masimo SET has been clinically proven in more than 100 independent clinical and laboratory studies to provide the most trustworthy continuous noninvasive arterial blood oxygen saturation and pulse rate measurements even under the most difficult clinical conditions, including patient motion and low peripheral perfusion. These studies prove Masimo SET delivers improvements in outcomes, safety and efficiency by providing accurate measurement of arterial oxygen satuaration and pulse rate and significantly reducing false alarms while improving detection of true events.

Joe E. Kiani, Chairman & CEO of Masimo, stated, "We are happy that Apria has chosen Masimo SET technology to help keep their patients safe in a home health care environment and are excited to be partnering with the leading name in home health care. This partnership with Apria marks Masimo's entry into the home care market in the USA. Our mission has been to improve patient safety and reduce cost of care by taking noninvasive monitoring to new sites and applications. We are proud to form this partnership with Apria to bring reliable Masimo SET pulse oximetry into the home care setting."

About Masimo

Masimo develops innovative monitoring technologies that significantly improve patient care-helping solve "unsolvable" problems. In 1995, the company debuted Read-Through Motion and Low Perfusion pulse oximetry, known as SET, and with it substantially reduced false alarms and increased pulse oximetry's ability to detect life-threatening events. More than 100 independent clinical and laboratory studies have confirmed that Masimo SET technology allows clinicians to accurately monitor blood oxygen saturation in critical care situations. Our Masimo SET platform has significantly addressed many of the previous technology limitations, has substantially contributed to improved patient outcomes and has been referred to by several industry sources as the gold standard in pulse oximetry. In 2005, Masimo introduced Masimo Rainbow SET Pulse CO-Oximetry, which, for the first time, noninvasively monitors the level of carbon monoxide and methemoglobin in the blood, 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."
