Chronic high altitude pulmonary edema |

High-altitude pulmonary edema (hape) (hapo spelled oedema in british english) is a life-threatening form of non-cardiogenic pulmonary edema (fluid accumulation in the lungs) that occurs in otherwise healthy mountaineers at altitudes typically above 2,500 meters (8,200 ft). highlight High-altitude pulmonary edema - wikipedia.

High-altitude pulmonary edema. in normal lungs, air sacs (alveoli) take in oxygen and release carbon dioxide. in high-altitude pulmonary edema (hape), it's theorized that vessels in the lungs constrict, causing increased pressure. this causes fluid to leak from the blood vessels to the lung tissues and eventually into the air sacs. highlight Pulmonary edema - symptoms and causes - mayo clinic.
