Abstract
A device and method for detecting complications during an extracorporeal blood treatment are provided. During the dialysis treatment, the dialysance or clearance may be continuously determined at successive points in time based on a measured change in a physical or chemical characteristic quantity of the dialysis liquid, for example, the ion concentration of the dialysis liquid. In the event a significant change in the dialysance or clearance is established, the determination of the recirculation may be effected based on a measured change in a physical or chemical characteristic quantity of the blood. When both a significant change in the determined dialysance as well as in the recirculation occurs, a complication may be assumed with regard to a bad vessel access. Alternatively, a complication may be assumed with regard to the dialyzer. The present invention may allow the continuous monitoring during the dialysis treatment to ensue solely on the basis of the change in the measured dialysate-side characteristic quantities.
