High-altitude pulmonary edema (HAPE) is a life-threatening, noncardiogenic form of pulmonary edema afflicting certain individuals after rapid ascent to high altitude above 2,500 m (approximately 8,200 ft). Although altitude-related illness has been documented at altitudes as low as 2000 meters, most cases occur at altitudes of greater than 2500 meters.
