High altitude oxygen test
Webfects of high altitude on human physiology are due to the low oxygen partial pressure of the inspired air; consequently, different ad-justments are needed to improve the tissue oxygen availability. Hypobaric hypoxia causes an increase in ventilation (see West, 1993), increases in arteriovenous O 2 differ-ence, hemoglobin concentration, and hemat- Websimulating conditions encountered at high altitude.
