In 1922, the British Everest mountaineering team used oxygen to climb at high altitude for the first time, which was the second time that humans climbed Everest. At that time, the oxygen equipment was used as the oxygen supply for climbing, and the role of oxygen was verified under ultra-high altitude conditions.
The use of oxygen in mountain climbing has two main functions
ü Auxiliary: reduce the mountain response on the plateau, improve the efficiency of mountain climbing, and reduce the possibility of serious high inversion in the normal climbing process. It is usually used in mountains above 4000 meters.
Treatment: When severe high resistance occurs, timely use of oxygen and rapid evacuation are the first priority to save lives. In case of personal injury, the use of oxygen will help to enhance the overall function, resistance and recovery rate of the human body. Therefore, even if there is no 8000m mountain climbing, the oxygen that the mountaineering team prepared for the attack will also be used in emergencies.
Serious hazard of hypoxia
Severe high altitude brain edema. Death may occur within 24 hours after onset.
Ø Severe high altitude pulmonary edema. It may cause death within 48 hours after the onset of the disease.
Ø It seriously affects the consciousness, judgment and physical quality of climbers, leading to other dangers in climbing. For example, serious physical overdraft leads to inactivity and death; In addition to the low temperature environment, breathing causes serious temperature drop; Due to wrong judgment, it leads to fall, loss, and even death.
Ø Being in severe hypoxia for a long time, leading to damage to the central nervous system such as the brain. This damage is usually irreversible.
In addition to low temperature environment, serious frostbite is caused.
With the rapid development of social and commercial activities, there are more and more outdoor sports and activities that require rapid on-site oxygen supply, such as diving, spa, ocean research, underwater photography, underwater architecture, underground or cave exploration and archaeological research.
