Individuals may seek the advice of medical providers when considering travel to high altitude. This article provides a basic framework for counseling and evaluating such patients. After defining "high altitude" and describing the key environmental features at higher elevations, the physiologic changes that occur at high altitude and how these changes ...

High-altitude illness is the collective term for acute mountain sickness (AMS), high-altitude cerebral oedema (HACE), and high-altitude pulmonary oedema (HAPE). The pathophysiology of these syndromes is not completely understood, although studies have substantially contributed to the current understanding of several areas.

This article discusses prevention, recognition, and treatment of altitude illnesses, especially acute mountain sickness, high-altitude pulmonary edema, and high-altitude cerebral edema. Physicians advising travelers and trekkers who will be visiting high-altitude areas will find an organized approach to giving pretravel advice. Physicians practicing in

The Lancet Respiratory Medicine, 2012
Abstract Medical problems occur at high altitude because of the low inspired Po2, which is caused by the reduced barometric pressure. The classical physiological responses to high altitude include hyperventilation, polycythemia, hypoxic pulmonary vasoconstriction–increased intracellular oxidative enzymes, and increased capillary ...

Physics Today, 1950
Science has always been international, and where it has flourished it has been nurtured by the contributions of men from all nations. High altitude laboratories similarly are especially beneficial if they are organized on an international basis. High altitude laboratories can serve the scientific community in many ways.

The Journal of Nutrition, 1992
Food records confirm that there is a high risk of malnutrition at high altitudes because of the usual lack of fresh food. As to the use of pharmacologic properties of micronutrients, only some data on vitamin E are described. Two placebo-controlled studies showed that a prolonged stay at high altitude caused a decrease in physical performance and a ...

The sport of high-altitude climbing encompasses a number of factors of stress that supersede the usual endurance activities at lower altitudes. The effect of hypoxia on both physical and mental performance can be profound and, therefore, compound the risk. Much is yet to be known, particularly about the brain.

To the Editor.— I read Dr Houston's discussion on high altitude sickness (236:2193, 1976) with a great deal of interest. It has always occurred to me whenever reading articles about high altitude sickness that the clue to the origin of this condition lies in its name—altitude (that is, diminished barometric pressure). Human beings living at sea level
