The nose and throat at altitude
04/06/07:  High altitude mountaineers from the first ever reconnaissance expedition to Everest in 1921 complained about a variety of problems affecting their nose and throat.

Supplementary Oxygen and High Altitude
23/05/07:  The use of supplementary oxygen for climbing at high altitude has been debated for many decades.

Oxygen Delivery
20/05/07:  Oxygen delivery is a term used in medicine to describe the process of how oxygen is presented to the cells which need it for generating the energy which keeps us alive.

Sleep at High Altitude
18/05/07:  Ascending to high altitude forces climbers and trekkers to deal with many physiological challenges.

Hypoxia and Medicine
16/05/07:  Hypoxia, or lack of oxygen, is a very common phenomenon in medicine. Sudden and severe hypoxia such as drowning is obvious and frequently fatal.

Nutrition and Weight Loss Studies At Extreme High Altitude
14/05/07:  Life at high altitude has many different effects on the body. One interesting and important effect is the pronounced weight loss observed in people.

What is Hypoxia?
12/05/07:  Hypoxia, put simply, is a lack of oxygen. Oxygen forms approximately 21% of the air we breathe and is the part of the air which is vital for human life.

Translating the lessons learnt from hypoxia in the mountains
07/05/07:  "We need help urgently. We have a man in his forties who cannot move his right side"

High Altitude Eye Study
16/04/07:  As part of the Neurosciences work we are carrying out the most extensive high altitude eye study.

Medical Research Expeditions: 1960, 1981, 2007
06/04/07:  We arrived here at Everest Base Camp yesterday and I am writing this in a comfortable tent with a view of the Ice Fall one way and of Pumori the other.

Low Oxygen Research ? An Excuse for a Jolly up a Mountain?
04/04/07:  The single most asked question to Caudwell Xtreme Everest is: Why are you climbing a mountain when you could just use pressure chambers instead?

What is intensive care?
02/04/07:  Intensive care, also known as critical care, or intensive therapy, originated approximately 50 years ago as a response to a polio epidemic in Copenhagen.

Why going to Everest may help patients in intensive care
28/03/07:  One in six people are admitted to an intensive care unit in the United Kingdom during their life. Of these people, 20% will die whilst on the intensive care unit.
