Reascent following resolution of high altitude pulmonary edema (HAPE)

High Alt Med Biol. Spring 2001;2(1):53-5. doi: 10.1089/152702901750067927.

Abstract

There is an absence of information in the literature regarding reascent to high altitude following resolution of HAPE (high altitude pulmonary edema). This report presents three cases of HAPE that are notable for later reascent to a high summit (up to 8,850 m) within the time course of each expedition. These cases illustrate that careful, gradual reascent following recovery and acclimatization after an episode of HAPE precipitated by rapid ascent may be considered. The pathophysiology of HAPE is reviewed with a focus on the evidence for rapid reversibility of pulmonary vascular injury. The evidence for protective pulmonary vascular remodeling is discussed to further support such a recommendation for cases of uncomplicated HAPE.
