Belik L. Oxygen transport of human organism at different states of cardiovascular system

In the first time the detailed family of dependencies of oxygen consumption on its delivery was obtained under conditions of high, normal an insufficient heart pumping capacity. In the first time the dependencies which represent the conditions of oxygen exchange in pulmonary and systemic circuits at different level of heart pumping capacity were built. The detailed analysis of sys-temic oxygen delivery and consumption at normal, insufficient and surplus cardiac output was done. It was established that at the same level of oxygen content in the arterial blood of systemic circuit the oxygen content is decrease with decrease of cardiac output. At the same conditions in pulmonary circuit the venous blood oxygen content increases with increase of oxygen content in arterial blood.
