Xtreme Everest is a research consortium that organised and executed research expeditions at high altitude to investigate the human physiology of hypoxia (low oxygen levels) and thereby improve outcomes for people who become critically ill.

Currently, more than 20% of people admitted to intensive care in the UK each year die, and a significant number of those that survive never regain the same quality of life they had before.

We work with doctors, nurses and members of the public to try to find a way to reduce these numbers.

To date, Xtreme Everest have carried out 12 research studies: 10 at altitude and 2 in chambers and sea level testing prior to the Caudwell Xtreme Everest expedition which took place in 2007.
