High-altitude Pulmonary Edema in Emergency Department: A Review

High altitude pulmonary Edema (HAPE) is a severe form of high-altitude disease that, if left untreated, can result in death in up to half of those who are affected. Lowlanders who rapidly go to elevations more than 2500-3000 m are more likely to develop high altitude pulmonary Edema (HAPE). Individual sensitivity owing to a low hypoxic ventilatory response (HVR), quick pace of climb, male sex, usage of sleep medicine, high salt consumption, chilly ambient temperature, and intense physical effort are all risk factors. HAPE may be totally and quickly reversed if caught early and correctly treated. Slow climb is the most effective technique of prevention. A fall of at least 1000 meters, is the best and most certain treatment choice in HAPE. Supplemental oxygen, portable hyperbaric chambers, and pulmonary vasodilator medications (nifedipine and phosphodiesterase-5 inhibitors) may be beneficial. In this article we’ll be looking at the disease etiology, epidemiology, diagnosis and management.
