Abstract:
A method for determining at least one hemodialysis parameter during an extracorporeal blood treatment using a dialyzer divided by a semipermeable membrane into a blood chamber and a dialysate chamber; the method comprising:passing blood to be treated in an extracorporeal blood circulation path through the blood chamber at a preset blood flow rate;passing dialysate in a dialysate path from a dialysate source through the dialysate chamber to a drain at a dialysate flow rate;setting the dialysate flow rate in the dialysate path to a set dialysate flow rate where a concentration of a substance in dialysate flowing out of the dialysate chamber substantially adopts a concentration of the substance in the blood flowing into the blood chamber; andmeasuring the concentration of the substance in the dialysate flowing out of the dialysate chamber, the at least one hemodialysis parameter being a function of the concentration of the substance in the dialysate flowing out of the dialysate chamber.
