Abstract

A method for determining a pressure of a medical fluid in a fluid line by using at least one centrifugal pump includes detecting the pressure upstream of the centrifugal pump while considering an information about a pressure downstream of the centrifugal pump, or detecting the pressure downstream of the centrifugal pump while considering an information about a pressure upstream of the centrifugal pump. Thereby, at least one information about the volume flow in the fluid line and/or at least one information about a rotation speed of the centrifugal pump are considered, respectively. The invention also relates to a method for determining a volume flow, an arithmetic unit, a treatment apparatus, a digital storage means, a computer program product and a computer program.
