Claim Text:
1. Method for the attainment of a predetermined substitution target in a blood treatment unit, which comprises the following steps: a) Determining the filter properties by detecting at least two pressure measurement values by at least two pressure sensors within the blood treatment unit using a reference solution, prior to connecting a patient with the blood treatment unit, b) Comparing the detected pressure measurement values with reference values of the same patient which were detected in previous dialysis sessions or with reference values of a patient group, c) Calculating the substitution target based on the values according to at least one of step a) or step b), prior to a current blood treatment of a patient with the blood treatment unit, d) Measuring of pressure measurement values by at least two pressure sensors during the current blood treatment, e) Comparing the pressure measurement values measured according to step d) with reference pressure measurement values, f) Configuring a blood flow rate, a dialysate flow rate, or a substituate flow rate in case of deviation of at least one detected pressure measurement value from the reference pressure measurement value in order to achieve the substitution target for a given treatment time or to modify the treatment time for a given substitution target as little as possible.
