[Guideline] Luks AM, Auerbach PS, Freer L, et al. Correlation between single nucleotide polymorphisms in hypoxia-related genes and susceptibility to acute high-altitude pulmonary edema. Bartsch P, Maggiorini M, Ritter M, Noti C, Vock P, Oelz O. Nifedipine or other pulmonary vasodilators may be used to treat concurrent HAPE and HACE, but avoid lowering mean arterial pressure, as this may decrease cerebral perfusion pressure and thereby increase the risk for cerebral ischemia. She had continued ascending despite experiencing mild altitude symptoms at Namche (3440 m), with considerably worsened symptoms at Tengboche (3860 m). Its mechanism is via inhibition of the carbonic anhydrase enzyme which counteracts the respiratory alkalosis which occurs during ascent to altitude. Oxygen, if available, should be provided. Initial chest x-ray showing pulmonary infiltrates in the right lung especially in the right mid and lower lung zones indicative of pulmonary edema. 2019 Dec. 30 (4S):S3-S18. 2006 Oct 3; 145(7):497–506. 2015 Nov 3.

Dexamethasone alleviates vasogenic cerebral edema and improves endothelial integrity. HAPE is characterized by reduced exercise tolerance, exertional dyspnea, and cough, followed by dyspnea at rest, cyanosis, and productive cough with pink frothy sputum. [Medline]. In high-altitude pulmonary edema (HAPE), it's theorized that vessels in the lungs constrict, causing increased pressure. 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). Genet Mol Res. [Medline]. Prog Cardiovasc Dis. Kilimanjaro [19,341 ft (5,895 m)] in fewer than seven days); or (3) ascend to a sleeping altitude above 9,800 ft, then sleep more than 1,600 ft above the previous night's altitude without allowing a day off to acclimatize.

Prophylactic low-dose acetazolamide reduces the incidence and severity of acute mountain sickness. This causes fluid to leak from the blood vessels to the lung tissues and eventually into the air sacs. Klaus-Dieter Lessnau, MD, FCCP Former Clinical Associate Professor of Medicine, New York University School of Medicine; Medical Director, Pulmonary Physiology Laboratory, Director of Research in Pulmonary Medicine, Department of Medicine, Section of Pulmonary Medicine, Lenox Hill Hospital The patient was a middle-aged woman trekker who was emergency air-lifted from an altitude of 4410 m in the Nepal Himalayas to 1300 m in Kathamandu. 2015 Sep 28.
