Both the high altitude physiologist and the intensivist are challenged by the human organism
in a hypoxic environment. The variation in barometric pressure which occurs with latitude …

BACKGROUND: Portable peak flow meters are used in clinical practice for measurement of
peak expiratory flow (PEF) at many different altitudes throughout the world. Some PEF …

Exposure to high altitude induces physiological or pathological modifications that are not
always clearly attributable to a specific environmental factor: hypoxia, cold, stress, inadequate …

We hypothesize that plasma volume decrease (ΔPV) induced by high-altitude (HA) exposure
and intense exercise is involved in the limitation of maximal O 2 uptake (Vo 2 max ) at HA. …

Background: The incidence of cancer of the exocrine pancreas varies among populations,
being the fourth or fifth cause of cancer death in the West. Outcome remains poor and …

The aims of the present study were to determine the changes in forced vital capacity (FVC),
forced expiratory volume in 1 sec (FEV 1 ) and peak expiratory flow (PEF), during an ascent …

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 …

There have been a number of anecdotal reports of rhinitis and nasal obstruction occurring
at altitude. To quantify these reports, we investigated nasal obstruction and mucociliary …

1. Both hypoxia and hypocapnia can cause broncho-constriction in humans, and this could
have a bearing on performance at high altitude or contribute to altitude sickness. We studied …
