| Abstract: | The general hemodynamics and circulation in the organs of the abdominal cavity have been investigated in the presence of artificial circulation at a calculated rate of perfusion. The effect of vasoactive preparations (noradrenaline, Arfonad) on these characteristics is analyzed. The behavior of the microcirculation in the presence of artificial circulation created by an artificial circulation apparatus equipped with automatic control systems of original design has been studied. It has been found that disturbances of the microcirculation are responsible for the development of a state of hypoxia in organs and tissues in the presence of artificial circulation at a calculated rate of perfusion under conditions of controlled vasoconstriction or controlled hypotension. Stabilization of the arterial pressure and the functional state of the vascular bed in the presence of artificial circulation had a positive effect on the tissue blood flow and oxygen metabolism in the organs of the abdominal cavity.Paper presented at the First All-Union Conference on Engineering and Medical Biomechanics on the topic: Problems of Circulatory Hydrodynamics, Riga, October, 1975.D.
