Abstract
An apparatus for extracorporeal treatment of blood () comprising a treatment unit, a blood withdrawal line, a blood return line, a preparation line and a spent dialysate line. A control unit () is configured to calculate values of a parameter relating to treatment effectiveness based on measures of the conductivity in the spent dialysate line. An upstream variation of the value of the characteristic (Cd) is caused in the fresh treatment liquid with respect to a prescription baseline (Cd) thereby causing a corresponding and timely delayed downstream variation of the same characteristic (Cd) in the spent liquid flowing in the spent dialysate line (). An amplitude (ΔC) and/or a duration over time (ΔT) of the upstream variation are/is computed as a function of the flow rate (Qdial) of the fresh treatment liquid in a preparation line () or of the parameter correlated to the flow rate (Qdial).
