Common characteristics of altitude sickness?

Altitude sickness is mainly manifested as vomiting, tinnitus, headache, fever, loss of appetite, fatigue, dizziness, nausea, vomiting, abdominal distension, diarrhea, chest tightness, insomnia, dizziness, lethargy, dizziness, numbness of hands and feet, convulsions, etc. In severe cases, people may feel dull, uneasy and hallucinate. Edema, shock or spasm may also occur.

Travelers should not climb mountains too fast. It is best to keep a steady pace and cooperate with breathing. At the same time, they should adjust according to the steepness of the slope, so that the amount of exercise is directly proportional to breathing, especially to avoid shortness of breath. The rising height should be gradually increased, and the height of each climb should be properly controlled to adapt to the environment with low air pressure and thin air.

Don't travel too fast, get enough sleep and normal diet, and take short breaks regularly. During rest, you can do soft exercise and deep breathing to strengthen your circulatory function and high adaptability, and you should do more physical training to strengthen your oxygen intake function.

Prevention of altitude sickness

Before entering the mountain, both psychological and physical qualities should be adapted. If possible, it is best to carry out intermittent hypoxic stimulation and acclimatization exercise in the low-pressure cabin, so that the body can have certain physiological adjustment to the hypoxic environment from the plain to the plateau. At present, it is considered that climbing is the safest and safest way to prevent acute altitude sickness except those who are particularly prone to hypoxia.

Experts suggest that novices who want to enter the plateau above 4000m usually stay at 2500 ~ 3000 m for 2 ~ 3 days, and then the rising speed should not exceed 600 ~ 900 m every day. After arriving at the plateau, avoid drinking alcohol and taking sedatives and hypnotics for the first two days to avoid heavy physical activity. Light activity can promote adaptation to the environment.

Avoid cold and freeze, pay attention to heat preservation, and advocate the use of high-carbohydrate diet. Avoid alcohol and tobacco, and take sedatives and sleeping pills to ensure adequate liquid supply. The use of acetazolamide, dexamethasone, acanthopanax senticosus, compound codonopsis pilosula and sulpiride before going up the mountain may be effective in preventing and relieving symptoms of acute altitude sickness. Patients with organic diseases, severe neurasthenia or respiratory tract infection should not enter the plateau area.
