Method for calibrating a bioimpedance measuring device, and medical devices

The present invention relates to a method for calculating or approximating a value representing the relative blood volume (RBV) at a certain point of time, or a value representing the refilling volume of a patient that may be observed or found during or due to a blood treatment of the patient, the method involving considering one or more calculated or measured value(s) reflecting an overhydration level of the patient or an approximation thereof. It relates further to an apparatus and a device for carrying out the present invention, a blood treatment device, digital storage means, a computer program product, and a computer program.

The invention relates to a method and to a device for determining an optimum dialysate flow Qfor an extracorporeal blood treatment and to a blood treatment device comprising a device 18 for determining an optimum dialysate flow Qd. The optimum dialysate flow Qdis determined on the basis of a relationship describing the dependence of the clearance K on the dialysate flow Q. The device according to the invention comprises a measurement deviceB for measuring at least one value which is characteristic of the clearance K, a calculation and/or evaluation unitA of the device according to the invention being configured in such a way that the clearance K is determined on the basis of the at least one value which is characteristic of the clearance. The calculation and/or evaluation unitA is configured in such a way that the optimum dialysate flow Qis determined from the relationship describing the dependence of the clearance K on the dialysate rate Qon the basis of the measured clearance K, or the optimum dialysate flow Qis determined from the measured clearance K.
