Abstract
A method for determining a significant parameter (Cb, D, K, Kt/V) of the progress of an extracorporeal blood treatment carried-out using a membrane exchanger, includes the steps of successively circulating three treatment fluids through the exchanger. Each fluid has a characteristic Cd linked to at least one of the significant parameters of the treatment (Cb, D, K, Kt/V). The value of the characteristic in the first fluid upstream of the exchanger is different from the value of the characteristic in the second fluid upstream of the exchanger, the latter being itself different from the value of the characteristic in the third fluid upstream of the exchanger. Two values for each of the three treatment fluids are measured, respectively upstream and downstream of the exchanger, and at least one value of at least one significant parameter of the progress of the treatment (Cb, D, K, Kt/V) is calculated from the measured values.
