Patent ID: 8568595

Claim:
A method for determining or predicting the adequacy parameters that will be achieved at the end of a kidney substitution treatment during said kidney substitution treatment, the method comprising the steps of: providing the kidney substitution treatment by a machine having an extracorporeal blood system for pumping blood of a patient at a preset blood flow rate through a blood chamber of a dialyzer, the dialyzer divided by a semi-permeable membrane into the blood chamber and a dialyzing fluid chamber, flowing the dialyzing fluid at a preset flow rate through the dialyzing fluid chamber of the dialyzer to collect waste products from the patient after flowing through the dialyzing fluid chamber of the dialyzer, measuring continuously with a device any kidney substitution treatment related waste product to deliver together with data provided by the kidney substitution treatment machine an adequacy parameter, wherein the device is coupled with the dialyzer of the kidney substitution treatment machine, and comparing the slope of a preferable linear guideline for the adequacy parameter, which ends at a target adequacy parameter at the end of the kidney substitution treatment, to the slope of the delivered adequacy parameter and if the slopes are equal with the next delivered adequacy parameters a linearization is performed to determine or predict the adequacy parameter at the end of the kidney substitution treatment.
