How to adapt to plateau hypoxia?

Because of the high altitude and thin air in the Tibetan plateau, plateau oxygen deficiency exceeds the limit of most self-regulating tourists who just come from low-altitude areas, causing a series of discomforts and even diseases.

Hypoxia is mainly manifested as headache, dizziness, palpitation, shortness of breath, loss of appetite, nausea, vomiting, abdominal distension, chest tightness, chest pain, fatigue, weakness, slight facial edema, dry lips, runny nose and so on. In critical situations, blood pressure increases, heart rate increases, and even coma occurs. Some people are unusually excited, such as ambiguous, multi-lingual, gait instability, hallucinations, insomnia and so on. In severe cases, convulsions, coma, and pulmonary edema can occur. Failure to receive timely treatment can endanger life.

There are six things to pay attention to:

1, to make full ideological preparations, face up to the problem of high altitude oxygen. Keep your mind relaxed and relaxed. Do not be nervous. Because the tension and fear can make the heart beat faster and increase the symptoms of hypoxia.

2. Do not move immediately after you arrive in Tibet by plane or train. Should take a break first, the best posture is to maintain a seat or semi-recumbent position, so that high head and low is conducive to smooth breathing and reduce cerebral edema caused by hypoxia. In general, the human body can gradually adapt to an oxygen-deficient environment in a matter of hours or a day or two, because although Tibet is in a plateau region, it is suitable for human survival and living.

3, to maintain a steady breath, take appropriate deep breathing. Because deep breathing can enhance the alveolar absorption of oxygen, it is also one of the main physiological responses to altitude sickness.

4, diet should pay attention not to overeat, to choose some easily digested high carbohydrate and vitamin-rich diet. Eating food that is oversaturated and not easily digested can lead to increased blood circulation in the gastrointestinal tract, increased heart burden, and increased oxygen deprivation. Should eat more like vegetables, fruits and other digestible foods. In particular, should take some chocolate or sugar and other reserve, sugar foods in addition to easy digestion and absorption, the body's metabolic oxygen consumption is less, supplement energy to relieve hypoxia timely and effective. In addition, drinking water should be appropriate, too much will increase the burden on the heart, increase the symptoms of hypoxia.

5, according to individual conditions, appropriate choice of drugs to relieve altitude hypoxia. If severe headache does not continue to relieve, you can take painkillers; if chest tightness, chest pain can not be relieved can serve compound Danshen, rapid relief of heart and other expansion of vascular drugs.

6, if there is food, drugs and resting rest regulation, hypoxia symptoms continue to be relieved but worse, the patient should be promptly given oxygen therapy under the guidance of a doctor. If conditions permit, the patient should be taken to a place several hundred meters above sea level.

Hypoxia has such a great harm to the human body. How can we effectively treat hypoxic diseases?

There are many methods for the treatment of hypoxic diseases, but the currently recognized most reliable ones with less side effects are hyperbaric oxygen therapy. Hyperbaric oxygen therapy is a special treatment for placing the patient into a closed high-pressure chamber and inhaling pure oxygen. The so-called high pressure means that the air pressure in the cabin is higher than 1 atmosphere.

Hyperbaric oxygen therapy is an extremely safe clinical treatment. It has the characteristics of small side effects and significant effects. As long as the patient is undergoing hyperbaric oxygen therapy, listen carefully to the medical staff's mission before the start of treatment, eliminate ideological concerns, relax, and actively cooperate to be able to get good treatment and efficacy. The most commonly encountered discomfort in hyperbaric oxygen therapy is the pressure felt by the patient's binaural tympanic membrane due to the increase in cabin air pressure during the boosting process. This feeling is just like the feeling of people's ears when they take off and landing. It will not cause serious damage.
