This work presents a pulsatile control of a commercial rotary blood pump with a prototypic
control box. It is part of the project ECLA-Vent, which focuses on the optimization and
safety of ARDS treatment. The task of the rotary blood pump is the generation of a
bloodflow for extracorporeal lung assist. The power electronics for the pump drive were
adapted and a feedback control developed and evaluated to satisfy the high dynamic
demands of the pulsatile operating mode. Regarding the development of the feedback
controller the system model was adapted and parametrized. The discretized feedback
control was implemented for the operating software of the microcontroller architecture with
real time capabilities. The revised pump control was characterized in-vivo and in-vitro.
