Altitude sickness is a disease caused by series of physiological and pathological changes and compensatory adaptation changes caused by acute or chronic exposure to high altitude hypoxia.High altitude pulmonary edema(HAPE)and high altitude cerebral edema are life-threatening diseases that are likely to develop;chronic high-altitude sickness,if not taken seriously,can affect various systems of the patient.This article reviews the drug prevention and treatment of three types of altitude sickness,HAPE,high altitude polycythemia(HAPC),and high altitude pulmonary hypertension(HAPH),to provide a reference for the rapid adaptation of people entering high altitudes and the health care of high-altitude residents.
