Masimo and Respironics Announce an Expanded Relationship, the Adoption of Masimo Rainbow SET Pulse CO-Oximetry, and Settlement of Patent Dispute

August 1, 2006

Irvine, California - August 1, 2006, Respironics, Inc. today announced that it has decided to expand its relationship with Masimo and to adopt Masimo's pulse oximetry solution for situations requiring read through motion technology across all of its business units. Until now Respironics has only used Masimo SET in certain of its sleep and respiratory products. Respironics will be gradually incorporating Rainbow SET in all Respironics products where the improved capabilities will provide clear clinical improvements.   Respironics will be phasing out its Novametrix MARS oximetry product line over time but will continue to service customers until a comprehensive plan is in place.  This agreement between Respironics and Masimo also constitutes a release by Masimo of Respironics and its affiliates from certain patent infringement claims and provides Respironics with access to the Masimo Rainbow SET technology. 

Craig Reynolds, COO of Respironics stated, "Masimo SET is clearly the gold standard in pulse oximetry technology for its ability to reliably measure oxygen saturation and pulse rate during difficult situations, but with its new Rainbow Technology, Masimo further advances the science by being able to simultaneously measure carboxyhemoglobin and methemoglobin noninvasively, which until now could only be measured invasively.  Masimo and Respironics have enjoyed a great business relationship for over 10 years.  We are excited to be able to extend our existing relationship and again be one of the first companies to provide our customers with the latest advancements in noninvasive patient monitoring technology."

Joe E. Kiani, Chairman and CEO of Masimo stated, "We greatly value our relationship with Respironics and are happy to be expanding our relationship with this new agreement.  Respironics was one of the first OEM users of Masimo technology, taking our revolutionary read-through motion and low perfusion pulse oximetry technology to the sleep labs and home care when that was the business they focused on.  We are delighted to see Respironics not only make great headway in the hospital market with its ventilator products, but to take Rainbow SET to its customers around the world." 

Respironics stated that it will not be changing its financial outlook for guidance based on the events described in this press release.

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 virtually eliminated false alarms and increased pulse oximetry's ability to detect life-threatening events.  Over 70 independent clinical studies have confirmed that Masimo SET technology allows clinicians to accurately monitor blood oxygen saturation in critical care situations.  In 2005 Masimo introduced Rainbow SET and with it, 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.

Masimo, founded in 1989, has the mission of "Improving Patient Outcome and Reducing Cost of Care by Taking Noninvasive Monitoring to New Sites and Applications." Additional information about Masimo and its products may be found at www.masimo.com
