Abstract
A biomedical apparatus for pumping blood of a human or an animal patient through a secondary blood circuit is provided, including a blood pump, an inlet duct and an outlet duct for guiding blood of the patient to the blood pump and back to the patient. The apparatus further includes a measuring device with at least one pressure sensor for measuring pressure values in the patient's circulatory system. A controller is provided that includes at least two different preset control algorithms for regulating the operating point of the blood pump based on the measured pressure values. The controller is configured to select one of these preset control algorithms for being applied in dependence on the position of the at least one pressure sensor in the patient's circulatory system.
