Medtronic LIFEPAK 12 Defibrillator/Monitor Adds Masimo Signal Extraction Technology for Pulse Oximetry

IRVINE, Calif. and REDMOND, Wash., December 6, 2004 — Masimo Corporation, the innovator and leader of Signal Extraction Pulse Oximetry, and Medtronic, the world's leading medical technology company, today announced that Masimo SET® pulse oximetry technology is now available in LIFEPAK® 12 defibrillator/monitors.

Pulse oximetry continuously tracks pulse rate and oxygen saturation in the blood to determine trends and warn of decreasing saturation levels. The LIFEPAK 12 defibrillator/monitor is used in both mobile emergency medical services and hospital settings. Medtronic's LIFEPAK 20 defibrillator/monitor, which is used mostly in hospital and clinic settings, has included Masimo SET Pulse Oximetry technology since 2002.

"We design and build our products with an eye to the needs of both the users and the patients," said Robert White, president of Medtronic's Emergency Response Systems business unit. "Masimo SET technology has been a successful component of the LIFEPAK 20 and the inclusion of this technology in the LIFEPAK 12 will be very beneficial to the overall management of emergency patient care."

Joe E. Kiani, CEO of Masimo, stated, "We are proud to be working with Medtronic to help emergency care providers revive patients. We have always respected Medtronic's commitment to patient care, and we are pleased to be represented as the pulse oximetry technology of choice in Medtronic's products."
