Abstract
An apparatus and a method for extracorporeal blood treatment, especially for hemodialysis, wherein blood of a patient is flushed with a dialysate in a dialyzer and wherein a variable correlated with the plasma sodium concentration of the blood is measured. The composition of the dialysate then is adjusted in response to the variable measured so that the plasma sodium concentration of the blood at least at the end of the blood treatment has the same value as at the beginning. For measuring the variable correlated with the plasma sodium concentration of the blood, for example a bypass operation can be implemented in which the dialysate is guided past the dialyzer so that a residual volume on the side of the used dialysate at least partially adopts the concentration of the substances dissolved on the blood side.
