Abstract
An extracorporeal cardiac assistance system, comprising a pump being configured to create a fluid flow from a suction line to a pressure line of the system; further comprising a control device configured to control the pump and/or an adjustable flow limiter to provide an adjustable flow rate and/or a pressure, wherein the control device is configured to execute a support mode with a plurality of consecutive support flow rate pulses and/or support pressure pulses interposed on the fluid flow and to execute a weaning mode with a plurality of such pulses, wherein an amount of energy provided to the fluid flow with each pulse is lower in the weaning mode than in the support mode.
