[Integral mechanisms of regulation of oxygen delivery and consumption in human body].
With new algorithms of pattern recognition three types of regulation of oxygen delivery and consumption were studied: at normal regulation, hypo- and hyperfunction of heart. It is shown that a surplus systemic blood flow results in increase of arterio-venous shunt flow. Insufficient blood flow results in increase of arterio-venous gradient of blood oxygen content due to the increase of gradient of oxygen content on both sides of capillary wall and to activating of vasomotor function of microcirculatory arterial bed. Quantitative estimations of shunt and capillary blood flow are obtained.
