Periodic breathing and O2 saturation in relation to sleep stages at high altitude
(Aviat. Space Environ Med., 1990)
This study was designed to compare sleep organization at high altitude (HA) and sea level (SL) and to estimate the extent periodic breathing (PB) negatively influences arterial O2, saturation (SaO2). Six lowlanders were ...
La vie humaine en haute altitude : mythes et réalités
(Bull. Soc. Path Ex., 1989)
La vie à haute altitude présente des aspects biologiques et médicaux très intéressants. Pour certains pays, comme les pays andins, elle a également des implications socio-économiques. La majorité des villes importantes de ...
Comparison of cisternal and lumbar cerebrospinal fluid pH in high altitude natives
(Pflügers Arch., 1975)
Summary. Samples of cisternal or lumbar cerebrospinal fluid were obtained from 20 young male
volunteers born and living at high altitude (3500 to 4800 m). The pH, carbon dioxide and oxygen tensions, and bicarbonate ...
Oxygen deficit and debt in submaximal exercise at sea level and high altitude
(Journal of Applied Physiology, 1974)
Kinetics of O₂ uptake (Vo₂) during exercise (3 work loads, 2 time periods) show that for a given work load O₂ deficit is larger at high altitude (HA) than at sea level (SL). However, the relationship
between deficit and ...
La circulation cutanée au cours de l'adaptation à l'altitude
(Pflügers Arch., 1969)
Résumé. Débit, pression et volume ont été mesurés dans la main droite considérée comme représentative de la circulation cutanée. Ces mesures ont été faites comparativement à basse altitude (50 et 400 m) et à haute altitude ...
Effets de l'oxygénation sur la réponse ventilatoire au CO₂ chez l'homme à haute et basse altitude
(Journal de Physiologie, 1969)
The effects of smoking on a high altitude population. (La Paz, Bolivia, 3600m or 12,200ft)
(Tobacco and Health, 1990)
Barometric pressure (PB) decreases with increasing a altitude. Since oxygen concentration is about 21% in the air of
the whole atmosphere, its partial pressure is also 21% of PB. At the altitude of La Paz (3600)m or ...
Regional distribution of pulmonary blood flow in normal high-altitude dwellers at 3,650 m (12,200 ft)
(Respiration, 1975)
Abstract. Simultaneous isotope dilution curves were recorded from the right upper (QRUZ) and
right lower lung zones (QRLZ) by surface scanning in the sitting and recumbent positions in 15 normal high-altitude-born (HAD) ...
Heat exchange and energetic balance during exercise in highlanders and lowlanders at sea level and high altitude
(Environmental Physiology, 1973)
This study was designer to determine the effects of changes in both cutaneous circulation (15) and kinetics of oxygen uptake (20) at high altitude on mechanisms of heat exchange during exercise. From a theoretical point ...
