Angiotensin-converting enzyme genotype and arterial oxygen saturation at high altitude in Peruvian Quechua.
The I-allele of the angiotensin-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism has been associated with performance benefits at high altitude (HA). In n = 142 young males and females of largely Quechua origins in Peru, we evaluated 3 specific hypotheses with regard to the HA benefits of the I-allele: (1) the I-allele is associated with higher arterial oxygen saturation (Sa(O...
متن کاملOxygen saturation in high-altitude pulmonary edema.
High altitude, defined as elevations greater than or equal to 8000 feet (2438 m) above sea level, is responsible for a variety of medical problems both chronic and acute. The spectrum of altitude illness ranges from the common, mild symptoms of acute mountain sickness, such as insomnia, headache, and nausea, to severe and potentially fatal conditions, such as high-altitude pulmonary edema (HAPE...
متن کاملPulmonary pressure, cardiac output, and arterial oxygen saturation during exercise at high altitude and at sea level.
The response elicited by exercise on pulmonary pressure, cardiac output, and arterial oxygen saturation in 35 lifetime residents of high altitude has been studied at high altitude (14,900 feet above sea level), and 22 residents of low altitude have been studied at sea level. A procedure combining cardiac catheterization, arterial cannulation, and spirometry was carried out. The exercise was mod...
متن کاملABC of oxygen: oxygen at high altitude.
The number of people travelling to the high altitude regions, especially South America, Nepal, and India, has risen enormously in the past 10 years. Without special climbing ability these trekkers can be exposed to altitudes they will not have encountered in their home countries. For example, the height of Everest base camp is 5500 m whereas the top of Mount Blanc, the highest mountain in the A...
متن کاملOxygen saturation in children living at moderate altitude.
BACKGROUND Physicians caring for newborns and infants residing at or traveling to moderate altitude have little information available about the normal range for arterial oxygen saturation (SaO2) measured by pulse oximetry. To aid clinicians in making rational decisions about the oxygen status of children at moderate altitude, we measured SaO2 in newborns and infants who came to two family pract...
