General staff adaptability to mountains
The standard atmospheric pressure of people living at sea level is 760mm. The mercury is also an ATA. The air is a mixture of oxygen, nitrogen and other gases. The content of oxygen is 20.95%. With the increase of the topography, the pressure is gradually reduced. The partial pressure of oxygen in the alveoli, arterial blood and tissue also decreases accordingly. When people enter the plateau area from the plains, it usually takes 2-3 months to slowly adapt to the local environment of low oxygen, so that people can survive in this environment, and can perform normal or near normal mental and physical activity , but a degree of pro-border. If people can not adapt to the alpine hypoxic environment will occur alpine diseases, such as high altitude heart disease, high altitude polycythemia, high altitude hypertension, high altitude hypotension.
mountain sickness
The reason for the formation of mountain sickness is that the higher the altitude, the thinner the air, and the lower the air pressure. Therefore, the oxygen pressure needed by the human body is also reduced, but the oxygen content required by the human body remains unchanged, so that the human body maintains the blood Need oxygen content, it is necessary to increase the content of red blood cells, but the human body automatically increase the content of red blood cells takes a few days, so when you just entered the mountains, because of a sudden increase in height, the human body too late to adapt, resulting in insufficient supply of oxygen in the body The higher the height of the situation, the shorter the transition time and the more violent the reaction. This physiological reaction is generally called [Alpine].
The symptoms of mountain sickness are: vomiting, deafness, headache, shortness of breath, loss of appetite, fever, drowsiness, severe symptoms such as dullness, restlessness, mental excitement, thinking, loss of mind, hearing, vision, Odor, taste abnormalities, hallucinations, etc., may also occur edema, shock or paralysis. The methods of prevention include: The speed of climbing should not be too fast. It is best to calm down smoothly, and cooperate with breathing. At the same time, adjust according to the steepness of the slope, so that the amount of exercise is proportional to the breathing, and in particular, to avoid shortness of breath. The height of ascent should be gradually increased, and the height of daily climbing should be controlled to adapt to the low air pressure and thin air environment. Travel should not be too tight, sleep, diet should be sufficient and normal, regular short-term rest, soft and deep breathing at rest to strengthen the circulation and a high degree of adaptation, usually should be more physical training to increase oxygen function. First aid for mountain sickness: Oxygen supply and height reduction are the most effective first aid treatments. If there is a shock phenomenon, priority should be given to treatment, and attention should be paid to loss of temperature and other complications. Take a rest immediately and move the patient to a place without wind. If the pain is severe, you can take analgesics to relieve pain. If you still can not adapt, you need to reduce the height until the patient feels comfortable or the symptoms are significantly reduced. In general, people with mountain sickness can be cured when they fall to the ground. Despite this, serious patients still need medical treatment.
