An Indirect Monitoring System for Controlling Rotor Blood Pumps

Control of rotor blood pumps by rotor rotation rate should be adapted to the requirements of the patient’s body. Physiological control of rotor blood pumps is based on information about the blood circulation system. The sensors should not contact the patient’s body fluids, so an indirect control system is suggested in this work. The system is based on information about pump current and rotor rotation rate. The indirect control system gives important information about parameters of the blood circulation system and the blood pump.
