Functional homology in response of human cardiovascular system to hypoxia and hypercapnia under various environmental conditions

The authors studied physiologic peculiarities associated with cardiorespiratory response to hypoxia and hypercapnia in various climate and geographic conditions, to combined effects of hypoxia, hypercapnia and physical burden, in artificial atmosphere with various velocity of hypoxia and hypercapnia increase. The studies were based on a hypothesis of universal mechanism that describes regulation of gas-transporting system and is aimed to supply oxygen to the body under ecological hazards. The authors revealed similarity of circulatory and respiratory responses to hypoxia and hypercapnia in various ecological circumstances.
