Abstract
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 wherein the kidney substitution treatment is provided by a machine, which has an extracorporeal blood system pumping the patient blood through the blood chamber of a dialyzer, wherein the dialyzing fluid collects the waste products from the patient after flowing through the dialyzing fluid chamber of the dialyzer and wherein a device able to measure a adequacy parameter is coupled with the kidney substitution treatment machine and wherein the slope of a preferable linear guideline for the adequacy parameter is compared to the slope of the delivered adequacy parameter and if the slope of both are equal a linearization is performed to determine or predict the adequacy parameter at the end of the kidney substitution treatment.

21. 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. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
-
- 39. A control system using a Kt/V value as a target, a predicted Kt/V value as a control variable, and parameters influencing the Kt/V value as actuating variables, wherein said control system allows an individualized adjustment of a therapy to each patient.
