Masimo also receives the AARC Zenith Award for Equipment and Service Excellence at the 54th Annual International Respiratory Congress in Anaheim

IRVINE, Calif., Dec. 16 /PRNewswire-FirstCall/ -- Masimo (Nasdaq: MASI), the inventor of Pulse CO-Oximetry and Measure-Through-Motion and Low-Perfusion pulse oximetry, announced that the clinical benefit of its remote monitoring and clinician notification system, Masimo Patient SafetyNet, was featured in a presentation titled Global Perspectives of Facility-Prolonged Mechanical Ventilation Care at the American Association of Respiratory Care (AARC) 54th Annual International Congress in Anaheim, California, on December 15, 2008.

Gene Gantt, RRT and Manager of Business Development for Linde Respiratory Support Services (RSS), a leader in post-acute respiratory care, presented how weaning patients off ventilator care in a post-acute care setting provides improved outcomes and reduced costs. According to Mr. Gantt, a major challenge to weaning patients off ventilator care in the post-acute environment was a safe and easy-to-use patient surveillance system that could help clinicians preempt adverse events. Mr. Gantt reported that the integration of the Masimo Patient SafetyNet system into Linde's Knoxville, TN facility protocol has been a significant factor in successfully implementing their weaning protocol and achieving a 75% wean rate with an average length-of-stay of only 40 days. The initiative has been so successful at improving the quality of life for patients and reducing the overall cost of care that Linde-RSS has decided to expand use of the Patient SafetyNet system to both their Memphis and Chattanooga facilities, as well.

"Using the Masimo Patient SafetyNet System not only raised the bar in terms of the quality of care that could be delivered in a post-acute setting--proving to be the right thing to do for patient safety -- it is also paying for itself through clinical efficiency," Mr. Gantt explained. "Since our clinicians are no longer wasting their time chasing false oximetry alarms, they are freed up to focus on patient care."

In addition to the Patient SafetyNet presentation and the continued excitement generated by Masimo's noninvasive and continuous hemoglobin monitoring technology (SpHb), the company announced that it received the AARC's prestigious Zenith Award. More than 400 companies were eligible for one of five 2008 Zenith Award honors presented. The Zenith Award is AARC's top industry recognition honoring respiratory care equipment and pharmaceutical manufacturers for quality and service excellence. Award recipients are chosen via special ballot by the association's membership of more than 44,000 respiratory care professionals based upon the quality of its equipment and/or supplies, the accessibility and helpfulness of its sales personnel, as well as the company's responsiveness, service record, truth in advertising, and overall support of the respiratory care profession.

Masimo Founder and CEO, Joe E. Kiani, stated, "We are delighted to see the results of Linde RSS's use of Masimo SET and Patient SafetyNet and are honored that AARC members have chosen to recognize Masimo for the superior performance, service, and integrity that Masimo provides to the clinical community. Respiratory clinicians were among the first to embrace the performance of Masimo SET pulse oximeters 10 years ago, but they often faced challenges in gaining access to Masimo's pulse oximetry technology. It is gratifying to see that despite the challenges, so many hospitals and clinicians now have access to Masimo SET and the benefits that our technology brings to their day-to-day patient care. It is our pleasure to serve the respiratory care profession in their mission in caring for the critically ill."

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 Pulse CO-Oximetry, a breakthrough noninvasive blood constituent monitoring platform that can measure many blood constituents that previously required invasive procedures. Masimo Rainbow SET Pulse CO-Oximetry continuously and noninvasively measures total hemoglobin (SpHbTM), oxygen content (SpOCTM), carboxyhemoglobin (SpCO(R)), methemoglobin (SpMet(R)), and PVITM, 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."
