In March 1999 a team of 8 mountaineers (6 men and 2 women) climbed up the 6th highest mountain of the world: The Cho Oyo (8201 m), located in the high mountains of Tibet. During the expedition, we investigated the effects of high mountaineering on various psychological variables (e.g., anxiety) and psychophysiological variables (e.g. blood pressure, pulse, skin-resistance) as well as the ability to relax at different points of time (2 premeasures before, three measures during, and one post-measure immediate after the Expedition). Due to a long-term monitoring of the skin resistance, we can summarize that three different adaptation levels can be defined, that appear under increasing pressure: Inhibition of overload, unspecific hypersensibility and exhaustion. The results can show that a telemedical assessment is possible and necessary even under the circumstances of a highmountaineering expedition in order to determine and predict deficits in behaviour and health risks for individuals at high altitudes.
