Susceptible individuals can prevent HAPE by slow ascent, average gain of altitude not exceeding 300 m/d above an altitude of 2500 m. If progressive high altitude acclimatization would not be possible, prophylaxis with nifedipine or tadalafil for long sojourns at high altitude or dexamethasone for a short stay of less then 5 days should be recommended.

[1][2][3] High altitude pulmonary edema (HAPE): HAPE is a condition that occurs in people whoexercise at altitudes above 8,000ft without having first acclimated to the high altitude. The hallmark of HAPE is an excessively elevated pulmonary artery pressure (mean pressure 36-51 mm Hg), caused by an inhomogeneous hypoxic pulmonary vasoconstriction which leads to an elevated pulmonary capillary pressure and protein content as well as red blood cell-rich edema fluid. This causes fluid to leak from the blood vessels to the lung tissues and eventually into the air sacs. In: MacDonald RD, ed. Wilderness Environ Med. Freeman K, Shalit M, Stroh G.

Wilderness Environ Med. HAPE may lead to shortness of breath, coughing, rapid heartbeat, and decreased oxygen levels as a result of pressure from constricted pulmonary capillaries.
