This point is generally tagged as , less than 356 millibars of atmospheric pressure). The concept was conceived in 1953 by Edouard Wyss-Dunant, a Swiss doctor, who called it the lethal zone. All eight-thousander, 14 peaks above 8000 m in the death zone are located in the Himalaya and Karakoram of Asia. Many deaths in high-altitude mountaineering have been caused by the effects of the death zone, either directly by loss of vital functions or indirectly by wrong decisions made under stress, or physical weakening leading to accidents. An extended stay above without Bottled oxygen (climbing), supplementary oxygen will result in deterioration of bodily functions and death. Physiological background The human body has optimal endurance below elevation. The Atmospheric chemistry, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
