Abstract

The present invention relates to a method of determining the pressure or of a parameter correlated with the pressure in an extracorporeal circuit of a blood treatment apparatus, in particular of a dialyzer, wherein at least one blood pump which is driven by at least one motor is located in the blood circuit, wherein the motor current of the named motor and the blood flow or a parameter correlated therewith is measured for determining the pressure or the parameter correlated therewith and wherein the pressure p or the parameter correlated therewith is calculated from the measured values.
