Abstract
A method of controlling a blood pump having a predefined hydraulic performance including at least from the group consisting of estimating and measuring an instantaneous flow rate during operation of the blood pump at a predetermined rotational speed of an impeller of the blood pump, the instantaneous flow rate including a plurality of flow rate data points. The plurality of flow rate data points define a trajectory around at least one from the group consisting of an operational point of a predefined pressure-flow curve associated with the predetermined rotational speed of the impeller of the blood pump and a target operational point of a target pressure-flow curve different than the predefined pressure-flow curve. The predetermined rotational speed of the impeller is adjusted until the plurality of flow rate data points define a predetermined trajectory around at least one of the operational point and the target operational point.
