The present invention relates to an apparatus for an extracorporeal blood treatment having an extracorporeal blood circuit in which a dialyzer is arranged and having a dialyzate circuit, wherein the blood circuit is in fluid communication with a first chamber and the dialyzate circuit is in fluid communication with a second chamber of the dialyzer, and wherein the two chambers are separated from one another by a semipermeable membrane, with a dialyzate pump for a conveying of the dialysis solution being present in the dialyzate circuit, wherein the apparatus has a control unit that is configured to operate the apparatus in a first phase and in a second phase following the first phase, wherein the dialyzate pump is operated with a smaller flow rate in the first phase than in the second phase and/or wherein the dialyzate pump conveys a dialysis solution in the first phase that is of a higher concentration with respect to at least one component than in the second phase.

Apparatus for an extracorporeal blood treatment

A method that regulates supply of substituate in an extracorporeal blood treatment with an extracorporeal blood treatment apparatus comprising a dialyzer divided by a semipermeable membrane into a blood chamber and a dialyzing fluid chamber and a device for supplying substituate. An extracorporeal blood treatment apparatus that includes a device for regulating supply of substituate. Regulation of supply of substituate in the extracorporeal blood treatment takes place as a function of the rheological loading of the dialyzer. To regulate supply of substituate during extracorporeal blood treatment, rheological loading of the dialyzer is determined from transmembrane pressure on the dialyzer and flow resistance of the dialyzer and substituate rate is increased or reduced according to the loading. The selection of dialyzer parameters or blood parameters is therefore no longer necessary and the distinction between pre-dilution and post-dilution is also made obsolete.
