Abstract
A method of determining a system compressibility value of a medical membrane pump drive is provided which includes moving to a first and second pressure level and detecting a first and second operating parameter value of the membrane pump drive. The system compressibility value is determined on the basis of the detected operating parameter values and the membrane of the membrane pump drive is supported at a rigid surface during the determination of the system compressibility value.
