Altitude preexposure recommendations for inducing acclimatization.
For many low-altitude (<1500 m) residents, their travel itineraries may cause them to ascend rapidly to high (>2400 m) altitudes without having the time to develop an adequate degree of altitude acclimatization. Prior to departing on these trips, low-altitude residents can induce some degree of altitude acclimatization by ascending to moderate (>1500 m) or high altitudes during either continuou...
متن کاملEffect of sildenafil and acclimatization on cerebral oxygenation at altitude.
Phosphodiesterase-5 inhibitors decrease hypoxic pulmonary vasoconstriction under hypobaric hypoxia, but are not known to affect cerebral blood flow or oxygenation. The present study was designed to evaluate the effect of sildenafil on cerebral haemodynamics during acute exposure to altitude and after acclimatization. Ten subjects were studied 1 and 3 days after rapid ascent to 3480 m before and...
متن کاملThromboelastometry and Platelet Function during Acclimatization to High Altitude.
Interaction between hypoxia and coagulation is important given the increased risk of thrombotic diseases in chronically hypoxic patients who reside at sea level and in residents at high altitude. Hypoxia alters the proteome of platelets favouring a prothrombotic phenotype, but studies of activation and consumption of specific coagulation factors in hypoxic humans have yielded conflicting result...
متن کاملRespiratory and circulatory changes during acclimatization to high altitude.
The studies of decreased barometric pressure made by Paul Bert (1) during the latter half of the nineteenth century may properly be considered as the beginning of modern knowledge of, and interest in, the effects of oxygen lack upon the human body. During the same period the rapid development of mountaineering as a sport produced a new occupational disease-altitude sickness, Or seroche as it wa...
متن کامل[Hemoglobin and testosterone: importance on high altitude acclimatization and adaptation].
The different types of response mechanisms that the organism uses when exposed to hypoxia include accommodation, acclimatization and adaptation. Accommodation is the initial response to acute exposure to high altitude hypoxia and is characterized by an increase in ventilation and heart rate. Acclimatization is observed in individuals temporarily exposed to high altitude, and to some extent, it ...
