REFLEX ADAPTATION MECHANISMS OF CENTRAL HEMODYNAMICS IN ACUTE BLOOD LOSS AND HYPERBARIC OXYGENATION
In experiments on 25 mongrel dogs studied the dynamics of changes in central hemodynamics (cardiac index and stroke work index of the left ventricle) and features bioelectric activity of afferent cardiac vagal fibers (Baas) in modeling the animals hemorrhagic shock (BP = 50/40 mm Hg. Art.) by fractional blood loss and treat their hyperbaric oxygenation (HBO). It was found that the activation of Baas after exposure to HBO was accompanied by the restoration of violated in posthemorrhagic period of blood circulation (cardiac index and normalization of myocardial contractility). The important role of hyperbaric oxygen as a factor in the mobilization of the reflex adaptive responses of the cardiovascular system in acute shortage of blood in the body is shown.
