ABSTRACT:
A device and method are described to determine the concentration of a substance in blood flowing through a blood chamber of a dialyzer during extra corporeal blood treatment. The flow rate of dialysate flowing through the dialysate chamber of the dialyzer is reduced to a value at which the concentration of the substance at the outlet of the dialysate chamber is essentially the same as the concentration of that same substance in the blood at the inlet of the blood chamber. The concentration measurement can be carried out without interrupting the flow of dialysate.
