Acute altitude hypoxia will seriously affect people's thinking ability. At the altitude of 1500m, people's thinking ability began to be damaged, indicating that the complex intellectual activity ability of freshmen was affected. 3000 meters, all aspects of thinking ability decline, especially judgment. At 4000 meters, the handwriting is scrawled, the sentence is blunt and the grammar is wrong; Above 7000 meters, quite a few people can suddenly lose consciousness without obvious symptoms.
Lack of oxygen is one of the causes of death of mountaineers.
Oxygen is the lifeline and source of life for ordinary Everest climbers.
Because oxygen cylinders are heavy, no one wants to carry such heavy things up the mountain for nothing, so their oxygen carrying capacity is limited.
Assuming that the oxygen flow is large, the consumption will be particularly fast, and it will not be enough if you are not careful. There is also an oxygen bottle that has run out of oxygen but has not been replaced, or a bottle with little oxygen. Also, for example, the oxygen pipe is frozen, or the breathing valve is broken, which will have a fatal impact.
Film shooting environment:
The film was shot on the snowy mountains in Tianjin and Gangshika. The shot in Tianjin is naturally the shot before climbing the snow-capped mountain, and the shot on the snow-capped mountain behind is actually taken on the snow-capped mountain in Gangshika, which is a huge challenge for the actors.
Jason Wu is famous for his dedication. In order to shoot this film, he had extreme training in advance and specially experienced the feeling of climbing the snow-capped mountains. But on the snowy mountain at the foot of Mount Everest, tough guys like Jason Wu were tortured to tears. The environment here is really bad.

Climbing spirit in harsh environment;
In the era of 1960 and 1970, China mountaineers climbed the summit of Mount Everest, the world's highest peak, for the first time, which contained many attractions. Extremely cold climate, oxygen-deficient environment, steep mountains, strange journey and ever-changing extreme weather constitute many obstacles to prevent the hero from reaching the summit, which makes the film full of plot tension besides presenting the visual spectacle of the struggle between man and nature.
However, what really touches the climbers is not the plot and the picture, but a spirit that runs through the whole film, a unique climber spirit of the Chinese nation. This spirit runs through the whole film, and we are still excited to walk out of the cinema. In the eyes of the author, or in the films of climbers, this spirit of climbers has rich connotations.
The so-called climber spirit, first of all, is the fearless spirit of overcoming all difficulties and conquering nature. As we all know, Mount Qomolangma, which is more than 8,000 meters above sea level, is known as the roof of the world. It is covered with thick snow all year round. Climbing it requires great physical strength, endurance and superb skills. This is a formidable mountain.
From the dark side of the mountain where there is no sunshine all the year round, that is, the north slope of Mount Everest in China, it is even more difficult and unprecedented to reach the summit. However, nothing can frighten the heroic people of China. 1960, when the country was still in a difficult state of natural disasters for three years, China climbers climbed to the top of the North Slope for the first time in human history with simple mountaineering equipment.
After that, it climbed to the top again at 1975, and completed the first target mapping. The height of Mount Everest is 8844.43 meters, which was later adopted by the world.
