(3) Stop alcohol intake. Fifteen days before ascending to high altitude, the consumption of alcohol should be stopped. (4) Emotional stress. Unwanted emotional tension should be avoided, while optimism and aggressiveness should be maintained. (5) Patients with upper respiratory tract infection should be carefully monitored before and during the time at high altitude. However, delaying the ascent until the infection has been fully resolved is preferable. (6) Oxygen must be available at high altitude, either by maintaining high oxygen levels in living quarters or by supplying compressed oxygen tanks for use during physical activity. (7) Food and water sanitation. Diets containing high levels of carbohydrates and protein and low levels of fat are recommended. The intake of vitamins can also be increased. (9) The use of drugs such as Rhodiola rosea, Zangtianlu, Codonopsis compound tablets, Shenqi pollen tablets, and acetazolamide during the time at high altitude can also reduce the risk of HAPE.
