Hypoxia and Brain Blood Flowis devoted to consideration of the effects of the resultant hypoxemia on respiration and circulation. It seems likely, however, that acute responses and adaptations to hypoxia in the central nervous system also play key roles in determining man’s ability to ascend to high altitudes. Because, at leas

Hypoxic Versus Hypocapnic Effects on Periodic Breathing During Sleep periodic breathing at high altitudes, the mechanism of hypoxia-induced periodic breathing and its relationship to sleep remain unclear. In 1909 Douglas and Haldane (7) induced periodic breathing in normal humans after periods of acute voluntary hyperventilation and suggested the importance of both

Effects of Acclimatization on Sleep Hypoxemia at Altitudeimatization proceeds normally, the partial pressure of oxygen (..) in arterial blood increases over time. If acute mountain sickness (AMS) intervenes and becomes severe, however, acclimatization does not occur and arterial oxygenation worsens (9). There have been many studies on the effect of ventil

Respiratory Control in Andean and Himalayan High-Altitude Nativest the same high altitude (4, 9, 12, 28; see also 7, 14, 15). Previously it was thought that the level of adaptation in the fully acclimatized sojourners would be the same as in the native high-altitude residents (1; see also 9). To understand high-altitude adaptation, researchers at the Andean Insti

Ventilatory Function in Adaptation to High Altitude: Studies in Tibetn on earth, have had ample opportunity to adapt. One important adaptation is ventilation. Pulmonary ventilation is the first step in the transport chain that moves oxygen from the ambient air to the tissue cell. Failure of pulmonary ventilation in individuals who go to high altitude is considered ce
