ABSTRACT:
A method for determining the blood sodium level of a patient whose blood circulates through one compartment of an exchanger separated from a dialysis fluid by a semipermeable membrane, wherein the conductivity of the dialysis fluid of equilibrium with the plasma is determined by: changing in a selected manner the conductivity of the dialysis fluid at inflow the exchanger, measuring the conductivity of the dialysis fluid at outflow from the exchanger, determining a lag time t.sub.L of the change in conductivity of dialysis fluid between inflow to and outflow from the exchanger, and determining an equilibrium conductivity value of the dialysis fluid for which the conductivity at outflow from the exchanger at an instant t is equal to the conductivity at inflow at an instant t-t.sub.L. The invention also relates to an artificial kidney incorporating means for carrying out this method.
