AbstractWith ascent to high altitude, barometric pressure declines, leading to a reduction in the partial pressure of oxygen at every point along the oxygen transport chain from the ambient air to tissue mitochondria. This leads, in turn, to a series of changes over varying time frames across multiple organ systems that serve to maintain tissue oxygen ...

High-altitude retinopathy and altitude illness
Ophthalmology, 1999To determine the relationship between high-altitude retinopathy (HAR) and other altitude-related illnesses and establish a classification system for HAR.Observational case series.All 40 climbers among 3 Himalayan expeditions who ascended to altitudes between 16,000 and 29,028 feet above sea level (summit of Mt.

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).

Altitude poses physiological challenges to the sports participant in excess of those encountered at sea level. The main problem is hypoxia and the reduction in oxygen transport capacity, which is linked to the fall in alveolar oxygen tension. Training at altitude is imperative as preparation for competing there in aerobic events. The acute adaptations

In order to study the prevalence of hypertension and some of the factors relevant to its natural history, cross-sectional surveys were performed during the period 1967 to 1973 in five small Peruvian communities, two located at sea level and three above 13,000 feet of altitude.

Current Pain and Headache Reports, 2013
High altitude headache (HAH) has been defined by the International Headache Society as a headache that appears within 24 hours after ascent to 2,500 m or higher [1••]. The headache can appear in isolation or as part of acute mountain sickness (AMS), which has more dramatic symptoms than the headache alone.
