Abstract
An arrangement for extracorporeal life support is further developed in such a way that a pump actuating signal produces a wave-like surging and subsiding pump output for a pulsatile flow. The pump is preferably a non-occlusive blood pump, such as a diagonal pump, for example. In a preferred variant of embodiment the control signal is provided by an ECG. This allows the diastolic pressure to be increased in order to improve the oxygen balance of the heart muscle.
Claims17
Arrangement with a blood pump (1) and pump control unit (2), which has a computer (3) that converts a control signal (4) into a pump actuating signal (5), wherein the pump actuating signal (5) produces a wave-like surging and subsiding pump output for a pulsatile flow.
Method of operating a blood pump (1) in which the pump (1) is operated with an iterating output in order to produce a wave-like surging and subsiding pulsatile flow.
