Effects of altitude on the human body
WebJan 19, 2024 · High altitude is associated with increases in systemic blood pressure (BP), both rest and exercise heart rate (HR), and minute ventilation. Alveolar hypoxia and arterial hypoxemia induce pulmonary circulation vasoconstriction, resulting in increased pulmonary vascular resistance and pulmonary artery pressure (hypoxic pulmonary vasoconstriction). WebThe declined atmospheric pressure and reduced partial pressure of oxygen at high altitudes tend to decrease the temperature by several folds. Hypobaric hypoxia is a major threat to humanity at high altitudes, and its potential effects include altitude mountain sickness.
