Claim Text:
1. Method for the differentiation of disturbances of the flow resistance in a blood treatment system which comprises the following steps: a) measuring at least two pressure signals selected from the group consisting of (PB b) calculating the quotients and/or the differences from the pressure signals measured according to step a), wherein the quotients and/or the differences are calculated from the pressure signals selected from the group consisting of (PB c) repeating, at least once, the steps a) and b), wherein at the same at least two pressure sensors as measured in the previous measurement and from the measured pressure signals the same quotients and/or differences are calculated; d) generating at least one time trend from the measured pressure signals selected from the group consisting of (PB e) evaluating the at least one time trend, whether a change of the at least one time trend has occurred over a tolerance range; f) generating a pattern for the evaluation of the at least one time trend; g) assigning the pattern to a disturbance condition, such that a location and type of the disturbance condition within the blood treatment system is determined; h) displaying the disturbance condition on a display device of the central processing unit; and i) automatically eliminating, with the blood treatment system, the disturbance condition to return the flow resistance to within the tolerance range, if the system determines that the disturbance condition is of the type and location that can be automatically eliminated.
