摘要
The method allows determination of the re-circulation of blood in a vascular access (11) of a patient whose blood is being subject to treatment (12) in an extra-corporal circuit. The process includes regulating the flow rate of blood in the extra-corporal circuit and a predetermined value (QB), and determining a first value (HGBA0) of the parameter representing the concentration of blood in the extra-corporal circuit. A variation in the amplitude (QUF) of the ultra-filtration flow rate in the treatment appts. (12) is effected. A second value (HGBA3) of the concentration parameter is then determined. The re-circulation (AR) of the blood in the extra-corporal circuit is determined on the basis of the blood flow rate (QB), the ultra-filtration flow rate amplitude (QUF) and the two parametric flow rate measurements.
