Spacelabs Medical and Masimo Announce Latest Pulse Oximetry Technology Alliance

Spacelabs To Offer Masimo SET® SpO2 Technology in UltraviewSL Command Module

Issaquah, Wash., and Irvine Calif., September 19, 2005 - Spacelabs Medical, a leading manufacturer and distributor of patient monitoring systems, announced the availability of Masimo SET® SpO2 technology in Spacelabs' UltraviewSL Command Module. The new product offering is the latest step in the two companies' joint development initiatives, designed to provide "best in class" solutions for customers worldwide.

Masimo SET (Signal Extraction Technology) pulse oximetry is a highly advanced method of acquiring, processing and reporting arterial oxygen saturation and pulse rate. Combining proprietary signal processing algorithms with innovative sensor design, Masimo SET pulse oximetry enables adaptive filters to work in real time to accurately report changes in human physiology. Masimo SET SpO2 technology has been clinically proven to read through motion and low perfusion at a high level of accuracy, with some studies showing improved patient outcomes.

Spacelabs' UltraviewSL family of patient monitoring systems, including the SL2400 compact, SL2700 and SL2800 bedside monitors and SL3800 central monitor for hardwired, wireless and telemetry patients, enable clinicians to access customized, real-time patient data when and where it is needed.

Dave Tilley, President and COO of Spacelabs Medical, said, "We are pleased to offer Masimo's technology to Spacelabs customers throughout the world. We are committed to satisfying our customers with the solutions that best meet their needs. The agreement with Masimo is yet another example of this 'Customer First' philosophy."

Joe E. Kiani, CEO of Masimo Corporation, added, "Spacelabs Medical has a history of leadership and is poised to continue with its heritage. We are happy that together with Spacelabs, we can offer more clinicians and patients access to Masimo SET pulse oximetry."
