Livewire (Internal / External / PR) - Irvine, California - July 14, 2009 - Masimo (NASDAQ: MASI), the inventor of Pulse CO-Oximetry? and Measure-Through Motion and Low-Perfusion pulse oximetry, has received the 2009 Silver Medical Design Excellence Award in the general hospital devices and therapeutic products category for the Masimo Rad-87 Pulse CO-Oximeter. The award recognizes Rad-87's excellence in medical technology engineering and design as an intuitive bedside patient monitor that helps improve clinical efficiency and keep patients safe when a clinician can't be at the bedside.

The Masimo Rad-87 features the breakthrough noninvasive blood constituent monitoring capabilities of Masimo Rainbow SET? Pulse CO-Oximetry for continuous monitoring of hemoglobin, carbon monoxide, methemoglobin, PVI (fluid responsiveness), perfusion index, and measure through motion pulse oximetry with upgradability to acoustic respiration rate monitoring.  Its built-in 802.11a/b/g radio allows wireless communication with the Masimo Patient SafetyNet remote monitoring and clinician notification system to provide patients with an enhanced level of safety on general care floors. Designed for ease-of-use, the Rad-87 allows the features clinicians need most often to be accessed with a single touch. And, as the first Masimo Rainbow SET device with a bright white LED-based display, its high contrast visual display allows measurements to be clearly seen from across the room, while an innovative new device profile feature lets clinical settings be customized and color-coded for a particular care area.

Masimo Founder and CEO, Joe E. Kiani, stated, It is an honor to receive our third Medical Design Excellence Award for product design and engineering innovations that improve healthcare delivery and advance medical practices. We received the Gold Medical Design Excellence Award in 2006 for the Masimo Rad-57 Pulse CO-Oximeter and in 2001 for the Masimo Radical Signal Extraction pulse oximeter.

The Medical Design Excellence Awards (MDEA) competition is the only awards program that exclusively recognizes advances in the design of medical products and the achievements of medical device manufacturers responsible for the groundbreaking innovations that are changing the face of healthcare. 2009 MDEA winners were announced and honored at the June 10th ceremony during the Medical Design & Manufacturing (MD&M) East Conference and Exposition in New York.

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 continuously and noninvasively measures total hemoglobin (SpHb?), oxygen content (SpOC?), carboxyhemoglobin (SpCO?), methemoglobin (SpMet?), and PVI?, 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.
