Thromboelastometry 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 کاملMan's respiratory response during and after acclimatization to high altitude.
I NCREASED pulmonary ventilation in response to lowered oxygen pressures has long been recognized in man. For a given oxygen pressure, however, this response is not the same for acclimatized and unacclimatized man. In order to analyze the changes which occur during the process of adaptation, various types of experiments have been designed. It is our objective I) to describe the difference in al...
متن کاملAltitude 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 کاملInhaled nitric oxide for high-altitude pulmonary edema.
BACKGROUND Pulmonary hypertension is a hallmark of high-altitude pulmonary edema and may contribute to its pathogenesis. When administered by inhalation, nitric oxide, an endothelium-derived relaxing factor, attenuates the pulmonary vasoconstriction produced by short-term hypoxia. METHODS We studied the effects of inhaled nitric oxide on pulmonary-artery pressure and arterial oxygenation in 1...
