[Analysis of control systems for artificial circulation devices]

A variant of a complex approach to solving the problem of ensuring the optimal perfusion, based on the separation of the ECA-organism system parameters into 4 subsystems, is proposed. An automatic control of the entire set of the extracorporeal circulation parameters is accomplished in the hierarchial order, with due consideration for the necessity to provide a fast response and physiological significance for the organism of the characteristics and factors subject to correction. The criteria for the adequacy of the extracorporeal circulation should be brought into a dynamic relation to the actual state of the organism. The composition of the blocks making up the system of the extracorporeal circulation regulation is discussed.
