Effects of age and gender on success and death of mountaineers on Mount Everest.

Increasing numbers of climbers are attempting Mount Everest, the highest mountain on Earth. We compiled interview data and computed the probabilities of summiting and of dying as a function of climber age and gender (2211 climbers, spring season) for the period of 1990-2005. Men and women had similar odds of summiting and of dying. However, climbers older than 40 years have reduced odds of summ...

Real-Time Electrocardiogram Transmission from Mount Everest during Continued Ascent

The feasibility of a real-time electrocardiogram (ECG) transmission via satellite phone from Mount Everest to determine a climber's suitability for continued ascent was examined. Four Taiwanese climbers were enrolled in the 2009 Mount Everest summit program. Physiological measurements were taken at base camp (5300 m), camp 2 (6400 m), camp 3 (7100 m), and camp 4 (7950 m) 1 hour after arrival an...

Advancing technologies in clinical medicine: the Yale-Mount Everest telemedicine project.

In the spring of 1999, just before the monsoon descended upon the Himalayas, physician-climbers and scientists brought a novel telemedicine program from the Yale School of Medicine to the remote and harsh environment of the Base Camp of Mount Everest. They implemented and tested new telemedicine technologies in a high-altitude environment well-known to push humans to the limits of their physiol...

Mental Strategies of Elite High Altitude Climbers: Overcoming Adversity on Mount Everest

Climbing Mount Everest Without Oxygen

The ascent of Mount Everest (altitude 8,848 m) by two climbers without supplementary oxygen in 1978 was a feat that astonished many physiologists; indeed, measurements of maximal oxygen uptake at lower altitudes suggested that it would be impossible. Data obtained in 1981 at extreme altitudes, including the summit itself, showed that man can tolerate the extreme hypoxia only by an enormous incr...
