Abstract
In a method for the determination of the viscosity (&eegr;) of a liquid, e.g. of blood, which is forwarded by a pump, e.g. a blood pump, said pump having a rotor for the forwarding of the liquid from the inlet of the pump to the outlet, the rotor is used for the determination of the viscosity (&eegr;). For the determination of the viscosity (&eegr;) of the liquid no spatial deflection of the rotor from its operating position takes place, but rather the rotor is left in its operating position and the viscosity (&eegr;) is determined from measurement parameters of the pump or of the rotor respectively.
