Radiographics. <]>> HAPE is the most common cause of death related to high altitude. High-altitude pulmonary edema (HAPE) is a life-threatening noncardiogenic form of pulmonary edema (PE) that develops in nonacclimatized persons after rapid ascent to altitudes above 2000 to 3000 m. HAPE is primarily a pulmonary disorder, whereas acute mountain sickness (AMS) and the much less frequent high-altitude cerebral edema, are neurologic disorders. 65 42 The pathophysiology, clinical presentation, treatment, and prevention of HAPE are reviewed here. AU Luks AM, Swenson ER, Bärtsch P SO Eur Respir Rev.

The main clinical pictures are represented by acute mountain sickness, high altitude pulmonary edema (HAPE), high altitude cerebral edema. High-altitude pulmonary edema (HAPE) is a life-threatening form of non-cardiogenic pulmonary edema (fluid accumulation in the lungs) that occurs in otherwise healthy people at altitudes typically above 2,500 meters (8,200 ft). High Altitude Pulmonary Edema in Children: A Single Referral Center Evaluation. 0000030339 00000 n It is a multifactorial disease involving both environmental and genetic risk factors. It is caused by sub-acute hypoxia in susceptible subjects. Although acute respiratory distress syndrome is the most common cause of noncardiogenic pulmonary edema, NPs also should be familiar with several other less common causes, including transfusion-related acute lung injury, neurogenic pulmonary edema, preeclampsia / eclampsia, opioid overdose, high-altitude pulmonary edema, and pulmonary embolism. Among the variety of theories put forth, one argument that has been made and amplified via social media is that COVID-19 lung injury is not like typical acute respiratory distress syndrome (ARDS) and instead is similar to high altitude pulmonary edema (HAPE) (Solaimanzadeh, 2020). Unable to process the form. Its study may provide lessons for the more complicated situation of hypoxia in patients undergoing intensive care.

This, in turn, induces endothelial leakage, which results in interstitial and alveolar edema without diffuse alveolar damage. It is the most common fatal manifestation of altitude illness. startxref Pulmonary edema is due to the movement of excess fluid into the alveoli as a result of an alteration in one or more of Starling's forces. The current leading theory of its patho-physiology is that HACE is a vasogenic edema; that is, a disruption of the blood–brain barrier, and we review possible mechanisms to explain this. JAMA.
