A control circuit for controlling a pump speed of a blood pump implanted in a patient including a processor in communication with the implanted blood pump, the processor having processing circuitry configured to reduce a pump speed relative to a standard set speed based on a timing of a systole phase of the patient, the systole phase including a first segment during which a ventricular pressure is at its greatest and a second segment occurring after the first segment during which the ventricular pressure is at its lowest, the pump speed being reduced during the second segment.

Blood pump algorithm for preventing and resolving left ventricular suction through dynamic speed response

A method of responding to an adverse event associated with an implantable blood pump including detecting the adverse event, reducing a pump speed of the blood pump relative to a set pump speed in response to the detected adverse event, and determining whether at least one of a group consisting of the adverse event and a second adverse event is present following the reducing of the pump speed of the blood pump. If the at least one of the group consisting of the adverse event and a second adverse event is not present, the method includes increasing the pump speed to the set pump speed and if the at least one of the group consisting of the adverse event and a second adverse event is present while increasing the pump speed to the set pump speed, the method includes reducing the pump speed to a maximum safe operating speed.
