Preparations before traveling to Tibet (especially about altitude sickness)

Altitude sickness, that is, altitude sickness, means that people who are not used to it quickly enter the plateau area above 3000 meters. Due to the decrease of oxygen partial pressure at atmospheric pressure, the body's tolerance to anoxic environment is reduced, and it is difficult to adapt to it, resulting in hypoxia, which leads to a series of altitude disorders. Of course, in addition to the factors of altitude hypoxia, there are also bad weather such as wind, rain, snow, cold and strong ultraviolet radiation, which will aggravate the altitude imbalance and cause different degrees of altitude imbalance. Altitude sickness-Symptoms Some people who enter the plateau for the first time will have headache, dizziness, dizziness, tinnitus, general fatigue, difficulty in walking and falling asleep within 24 hours at an altitude of 3,000 meters. In severe cases, symptoms such as abdominal distension, loss of appetite, nausea, vomiting, palpitation, shortness of breath, chest tightness, purple complexion, swelling of lips or face appear. When these symptoms appear, you should stay at the original height and rest for 3~5 days, or immediately lower the height by hundreds of meters, which can generally return to normal. Preparation-Some necessary equipment and medicines for entering Tibet: I once took Jing Tian Honghua capsule, and the effect was very good. I can buy it online. I bought it from Taobao. Suggest that I start taking it 7- 10 days before going, and the effect will be better. Clothing: Wear thin long-sleeved clothes in spring and autumn, and thick warm coats are also essential. Gloves, scarves, sunglasses, sun umbrellas, outdoor sunscreen lotion, lotion and lip balm should be brought together. These are all necessary items. Food: Because of the long riding time and different tastes, it is best to prepare dry food. The food you must bring is chocolate, because the altitude is high, the air is thin, and the human body consumes energy quickly. You must eat more high-calorie chocolate to replenish your strength. How to prevent altitude sickness in Tibet 1? You must have a comprehensive and strict physical examination before entering the plateau. Patients with serious heart, kidney and lung diseases, severe liver diseases and anemia are not allowed to venture to the plateau. When doing a comprehensive physical examination before entering Tibet, I found that my vital capacity decreased slightly. 2. Drug prevention. I'd like to introduce Jing Tian Honghua Capsule to you. Suggested administration method: Jing Tian Honghua Capsule takes 3 capsules in the morning and evening 7- 10 days in advance. The course of treatment depends on the specific situation. If you want to stay in the plateau for 3 or 4 months, you need to eat for half a month. The medicine has the effects of resisting altitude sickness, improving human immunity, enhancing blood circulation, resisting fatigue, resisting aging, dredging blood vessels and supplementing blood oxygen. It is recommended to carry sleeping pills, such as alprazolam or estazolam tablets, and cold medicines, such as Tylenol cold tablets or Gankang tablets. 3. Adaptive exercise. Before traveling to the plateau, we should carry out sports activities such as climbing mountains, running, playing ball, carrying loads and marching, which can play a positive role in adapting to the anoxic environment. I didn't do it, not because I didn't want to, but because I couldn't. The day before I entered Tibet, I was still in the clinical front line, and all kinds of pressures in my work and life made me exhausted and exhausted. I think this may be another reason for my severe altitude sickness. Therefore, I suggest that the next batch of comrades who aid Tibet or friends who come to Tibet for tourism should take a vacation for ten days and a half months before entering Tibet. It is very beneficial to do some adaptive exercises above. Dr. Li from the medical team gave him more than 20 days off from Yiyang Central Hospital before he entered Tibet, resting and exercising at home, and his weight actually increased by 3 kilograms. I felt good after I entered Tibet, and there was almost no discomfort. 4. Overcome your inner fears. Frankly speaking, I do have a heavy psychological burden, and I am worried that some injuries will be irreparable. This may be another important reason for my severe altitude sickness. Before entering Tibet, we must establish the determination and confidence to overcome altitude sickness and eliminate unnecessary mental fears. The best way to avoid or reduce altitude sickness is to face it with a good attitude? Many reaction symptoms are caused by psychological effects or psychological effects. In fact, under normal circumstances, you can gradually adapt to the plateau environment in about two or three days, and the symptoms of hypoxia such as chest tightness, shortness of breath and dyspnea will disappear or be greatly improved. The vast majority of comrades in the Tibet aid medical team are like this. When you first arrive at the plateau, you should not walk fast, let alone run or do manual labor. After a week's rest, you can gradually increase a certain amount of labor. In addition, the plateau temperature is low and changes rapidly with the temperature. Change clothes in time, take fewer baths, and avoid catching a cold and consuming physical strength. I didn't pay attention to these when I first came, and I suffered a loss. I am lucky that I don't have acute high altitude pulmonary edema, because a cold is one of the main causes of this disease. 6. Adjust your life during the platform period. Food should be digestible, nutritious, high in sugar and multivitamins. Eat more fruits and vegetables and drink more water? Don't overeat, so as not to increase the burden on the digestive organs. It is forbidden to drink alcohol to avoid increasing oxygen consumption. When sleeping, the pillow should be padded higher, and the semi-lying posture is the best. 7. After entering the plateau, don't take oxygen at first, but try to adapt yourself, otherwise you may never be able to live without oxygen at the plateau (very dependent). But the symptoms of altitude maladjustment are getting more and more serious, even for people who are obviously at rest. At this time, you can't be a hero. Oxygen should be inhaled immediately and sent to the hospital to prevent the adverse consequences caused by acute high altitude pulmonary edema.
