What are the symptoms of altitude sickness in Tibet? How to overcome it?

1. Pulse (heart rhythm) frequency: The normal pulse rate in plain area is 72 beats/min, which can be increased to 80-90 beats/min when you first arrive at the plateau, and it can reach 100 beats/min for individuals. After living for a period of time, you can recover.

Second, breathing: when hypoxia is mild, it is manifested as deepening and accelerating breathing, and the breathing frequency is further accelerated with the aggravation of hypoxia, and I feel chest tightness and shortness of breath. After adaptation, it will gradually return to its original level.

3. Blood pressure: Normal systolic blood pressure11kloc-0/20mmhg in plain area, and diastolic blood pressure 70-80mmhg. When I was in high school, due to the influence of vascular receptors and body fluids, blood vessels such as skin and abdominal organs contracted and blood pressure increased, thus ensuring the blood supply to the coronary artery and cerebral vessels of the heart and returning to normal after adaptation.

Nervous system: The central nervous system, especially the brain, is extremely sensitive to hypoxia. When there is mild hypoxia, the excitability of the whole nervous system is enhanced, such as emotional tension and excitement, and then symptoms such as headache, dizziness, insomnia and amnesia appear. After entering a higher altitude area, it turns from excitement to inhibition, showing drowsiness, indifference and unresponsiveness. A few serious people will lose consciousness or even coma, and will return to normal when they move to the lowlands. The severity of nervous system symptoms is often closely related to my psychological state and mental mood. People who are afraid of the plateau and lack psychological preparation will react more; On the contrary, happy people react less.

5. Digestive system: After entering the plateau, the secretion of digestive glands and gastrointestinal peristalsis are inhibited. Except for a slight increase in pancreatic secretion, the secretion of saliva, intestinal juice and bile of other digested foods decreased compared with the plain, and the gastrointestinal function was obviously weakened. Therefore, there may be a series of digestive system disorders such as loss of appetite, abdominal distension, diarrhea or constipation, and epigastric pain. After living in the plateau for a period of time, you can gradually recover.

At the plateau, if you continue to feel unwell, you should go to the hospital for treatment. The most important thing is not to walk into the plateau with fear.
