title: [Characteristics of the formation of human cardiovascular system reactions to acute hypoxia].
abstract: "Emergency" adaptation of the cardiovascular system of a healthy person to acute hypoxia produced by inspiration of a gas mixture containing 11% oxygen was accomplished in two ways: (a) with prevalence of the cardiac component, increase in the cardiac and systolic indices and end-diastolic volume in unaltered ejection fraction and diminished general vascular tonus; (b) with prevalence of the vascular component, decrease in the cardiac and systolic indices, end-diastolic volume, and muscular and skin blood flow and increase in peripheral resistance. After 10 days of training for hypoxia in a pressure chamber the reaction of the cardiorespiratory system to the hypoxia test was less pronounced but its trend was maintained.
