Medical problems occur at high altitude because of the low inspired Po(2), 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 density in muscle.

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.

Medical Clinics of North America, 2016
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 ...

This case report presents a 36 year-old male with a sudden loss of vision while taking part in an expedition in the Daulaghiri (8,167 metres high peak located in the Himalayan Mountain Range).High altitude retinal haemorrhage is a common condition in those mountaineers who reach altitudes over 5,500m.

We examined the effect of altitude up to 5200 m on marathon (42,195 m) performances.Eight elite and four good runners participated in a marathon at 4300-m altitude (A1), and five elite runners participated both in A1 and in a marathon at 5200-m altitude (A2).

Cough is a troublesome condition which affects many visitors to high altitude. Traditionally it has been attributed to the inspiration of the cold, dry air which characterizes the high altitude environment. This aetiology was brought into question by observations and experiments in long duration hypobaric chamber studies in which cough still occurred ...

Current Pain and Headache Reports, 2007
High-altitude headache (HAH) is an important public health problem because many of the millions of visitors to locations high above sea level get significant headaches each year. Headache is the most common symptom of acute exposure to high altitude.

The American Journal of Emergency Medicine, 1985
There are a number of conditions which can be grouped together as ARI. Many represent potentially fatal pathophysiological states that are rapidly reversible if identified and treated properly. Physiological alterations that result from the hypobaric hypoxia of altitude include cerebral vasodilatation, altered ventilatory patterns, pulmonary ...
