Abstract
An extracorporeal blood treatment apparatus is provided comprising a filtration unit connected to a blood circuit and to a dialysis fluid circuit, a preparation device for preparing and regulating the composition of the dialysis fluid; a control unit is configured for determining or receiving a proposed value of a sodium concentration for the dialysis fluid in the dialysis supply line and to determine a set value for the sodium concentration in the dialysis fluid as a function of the proposed value. For at least an interval of proposed values for the sodium concentration, the control unit is configured to determine the set value so that the set value is different from the proposed value and so that distinct set values are determined from distinct proposed values. The set value is biased towards a predetermined pivot value.
