Sistema adrenérgico en los residentes de grandes alturas
(Acta Andina, 1993)
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 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 ...
Effects of exercise on plasma erythropoietin in natives living permanently at high altitude
(Springer Verlag, 1992)
Abstract.
The effects of inspiratory hypoxia on the erythropoietin (EPO) system decisively depend on the duration of the exposure to the hypoxic environment. Whereas a stay of some hours in a hypobaric chamber leads to ...
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) ...
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 ...
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 ...
Effets de l'oxygénation sur la réponse ventilatoire au CO₂ chez l'homme à haute et basse altitude
(Journal de Physiologie, 1969)
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 ...
