MEDEX 2015: Prophylactic Effects of Positive Expiratory Pressure in Trekkers at Very High Altitude
Purpose: Positive expiratory pressure (PEP) breathing has been shown to increase arterial oxygenation during acute hypoxic exposure but the underlying mechanisms and consequences on symptoms during prolonged high-altitude exposure remain to be elucidated.

Contribution of Hypoxic Exercise Testing to Predict High-Altitude Pathology: A Systematic Review
Altitude travelers are exposed to high-altitude pathologies, which can be potentially serious. Individual susceptibility varies widely and this makes it difficult to predict who will develop these complications.

Acute mountain sickness (AMS) is a clinical syndrome occurring in otherwise healthy normal individuals who ascend rapidly to high altitude. Symptoms develop over a period ofa few hours or days. The usual symptoms include headache, anorexia, nausea, vomiting, lethargy, unsteadiness of gait, undue dyspnoea on moderate exertion and interrupted sleep.

Drug Use on Mont Blanc: A Study Using Automated Urine Collection [PDF]
Mont Blanc, the summit of Western Europe, is a popular but demanding high-altitude ascent. Drug use is thought to be widespread among climbers attempting this summit, not only to prevent altitude illnesses, but also to boost physical and/or psychological

AFIT 57-YEAR-OLD MALE trekker/climber presented at Dingboche, Nepal (4420 m), with severely limited exercise tolerance (it was an effort for him to walk from his room to the dining area), headache, and nausea. These symptoms first appeared 2 days earlier when he returned to Lobouche (5029 m) after climbing Kalapatar (5600 m).

Rhodiola crenulata extract for prevention of acute mountain sickness: a randomized, double-blind, placebo-controlled, crossover trial [PDF]
BACKGROUND: Rhodiola crenulata (R. crenulata) is widely used to prevent acute mountain sickness in the Himalayan areas and in Tibet, but no scientific studies have previously examined its effectiveness.

Effects of age on hypoxic tolerance in women
Introduction The prevalence of acute mountain sickness (AMS) is increasing with altitude (i.e., 10-25% at 2,500 m and 50-85% at ~ 5,000 m; Bärtsch & Swenson, 2013). While there is no error-free test to predict its occurrence, several risk factors and

Cerebral hemodynamic characteristics of acute mountain sickness upon acute high-altitude exposure at 3,700 m in young Chinese men. [PDF]
PURPOSE: We aimed at identifying the cerebral hemodynamic characteristics of acute mountain sickness (AMS). METHODS: Transcranial Doppler (TCD) sonography examinations were performed between 18 and 24 h after arrival at 3,700 m via plane from 500 m (n ...
