Mount Everest, Nepal - April 23, 2007

The Caudwell Xtreme-Everest Project Team, in co-operation with CORTEX Biophysik GmbH, will be putting SunTech Medical's OEM blood pressure technology through extreme conditions in the coming weeks. The team is currently climbing to the summit of Mt. Everest and will be performing a series of physiological tests along the way. Clinicians and scientists on the trek will assess human performance at the low oxygen levels found at extreme altitudes.

Part of the testing includes assessment with the MetaLyzer® cardiopulmonary exercise system from CORTEX. SunTech Medical provides OEM blood pressure technology for the MetaLyzer system to accurately and reliably obtain blood pressure measurements under the demanding conditions of stress and exercise.

"SunTech Medical is excited for the opportunity to see our blood pressure technology deliver valuable research data under such extreme conditions," says Dayn McBee, CEO "We are hopeful that the information our product provides will help the Caudwell team increase their understanding of critically ill patients."

SunTech provides blood pressure technology for use in a variety of challenging conditions including projects for NASA as well as for difficult clinical applications such as patient transport, dialysis, and cardiac stress testing.

The Caudwell Xtreme Everest Team hopes to gain an understanding of how human performance at extreme altitudes relates to conditions and reaction during critical illness. Results of this research may help physicians understand how patients react to low oxygen levels and lead to improved care for the critically ill. SunTech Medical certainly supports this goal and is proud that Cortex Biophysik and the Xtreme Everest Team chose SunTech Medical as their blood pressure solution.
