High altitude pulmonal edema (HAPE) is an acute noncardiogenic pulmonary edema caused by patchy hypoxic pulmonary vasoconstriction and have to be considered in acute care centers in regions with high mountains. This form of pulmonary edema is seen in people who travel from lower elevation to high elevation (>2500 m) and is related to altitude and rate of ascent.
HAPE mainly occurs due to exaggerated hypoxic pulmonary vasoconstriction and elevated pulmonary artery pressure. This kind of edema causes a form of consolidation which tends to occur along peribronchovascular bundle and if it is extensive it tends to occur as more mass like areas of opacification occurring with a typical peribronchovascular distribution. Slow descent is the most effective method for prevention.
