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. Seven of these had serious-to-severe HAPE (Hultgren grades 3 or 4). Ann Intern Med.

Early symptoms of HAPE include a nonproductive cough, dyspnoea on exertion and reduced exercise performance. The most effective and reliable treatment ofestablished. Among the variety of theories put forth, one argument that has been made and amplified via social media is that COVID-19 lung injury is not like typical acute respiratory distress syndrome (ARDS) and instead is similar to high altitude pulmonary edema (HAPE) (Solaimanzadeh, 2020). If progressive high altitude acclimatization would not be possible, prophylaxis with nifedipine or tadalafil for long sojourns at high altitude or dexamethasone for a … Far from describing all the physiological and pathological responses of the organism, in this review, the authors expose the state of the art in the knowledge of the responsiveness of the pulmonary circle to the acute or chronic hypoxic condition, its possible progression to the pulmonary arterial hypertension, the latter being more appropriately named High-Altitude Pulmonary Hypertension. A gradual ascent is the primary recommendation for the prevention of HAPE. High-altitude pulmonary edema (HAPE) Aside from medical conditions, hikers and mountain climbers are at risk for pulmonary edema that’s caused by rapid altitude ascent, generally above 8,000 feet.
