medical Definition of HAPE
- High-altitude pulmonary edema (HAPE) has been reported to occur at heights of 2,400 to 5,000 m (7,870 to 16,404 ft), with an incidence of 0.5% to 15%; greater risk is associated with young age, male sex, more rapid ascent, heavy exertion, and cold environment.

- Initially the HAPE victim will notice marked breathlessness with minor exertion and develop a dry, hacking cough. As greater amounts of fluid accumulate in the lungs, the victim develops increasing shortness of breath, even while resting, and a cough that produces frothy, often blood-tinged sputum. … Although HAPE is the most common cause of death related to high altitude, if recognized early and treated properly, it is easily and completely reversed.
