1, for personnel entering the plateau area. A comprehensive physical examination should be conducted. Generally fit people are more easily adapted to the low oxygen environment. Where pregnant women and have obvious heart. Lungs. Liver. Kidney and other diseases. Hypertension stage II. Suffering from epilepsy. Severe neurasthenia. Active peptic ulcer. Severe anemia. Are not suitable to enter the plateau area. 2, usually should strengthen physical exercise. The implementation of the step up. Make gradual adaptation. Domestic reports within 3 days from the plain to 4200m above sea level. The incidence of acute plateau disease 83.5%. And from 2261m by step adaptation in 7-15 days to 4200m. The incidence rate is only 52.7% (P<0.001). 3, drug prevention. To prevent acute plateau reaction due to hypoxia. Can be appropriate to use drugs to prevent. In recent years, domestic reports of oxygen loading adaptation. That is, the day before the departure of the resident or the day. Subcutaneous injection of oxygen between the waist 600 a l200ml effect is sure. This is the first choice of emergency measures for people who rush into the plateau or troop groups. Such as oxygen plus drugs to prevent acute plateau disease is more effective. It can completely control the people who enter the plateau in a hurry to not get sick. Therefore, it has better application value. 4.People who first enter the plateau should reduce physical labor. Later, depending on the degree of adaptation, gradually increase the amount of labor. The labor environment of plateau is mostly below 4000m. Therefore, the labor quota in the high altitude area (above 3500m) should be reduced accordingly. Attention should be paid to keep warm. Prevent acute upper respiratory tract infection. The research of Qinghai Provincial Occupational Disease Control Institute confirms. Highland low oxygen environment can make carbon monoxide (C0) toxicity increase. Aggravate the degree of poisoning of people exposed to C0. The recommended CO health standards for the plateau low oxygen environment are as follows: 20mg/m3 for an altitude of 2000-3500m. 15mg/m3 for 3500-4500m. The HbCO at this concentration should not exceed 2.5%. 5, when first entering the plateau should eat more carbohydrates. Multivitamins and easily digestible food. High carbohydrate food can provide glucose and enhance the diffusion capacity of the lungs. In order to carry out heavy physical work in the plateau. Alcohol consumption is prohibited. Those with symptoms of altitude sickness. It is best to sleep in a semi-recumbent position. To reduce venous return to the right heart and pulmonary capillary congestion.
