More than 200 individuals were studied at sea-level and in four laboratories on the trek to Everest Base Camp 5 300 m . Fifteen physicians climbed high on Everest and continued the studies as they ascended eight of these individuals reached the summit of Everest and succeeded in sampling arterial blood at 8 400 m on their descent. Core measurements included cardiopulmonary exercise testing neuropsychological assessment near infra-red spectroscopy of brain and exercising muscle blood markers and daily recording of simple physiological variables. The goal of CXE is to further our understanding of human adaptation to cellular hypoxia a fundamental mechanism of injury in critical illness with the aim of improving the care of critically ill patients. Caudwell Xtreme Everest CXE is a large healthy volunteer field study investigating human adaptation to environmental hypoxia 1 . The project is organised by the Centre for Altitude Space and Extreme Environment Medicine CASE Medicine at University College London. During April and May 2007 more than 200 individuals were studied as they were progressively exposed to hypobaric hypoxia on the trek to Everest .
