Effective bioimpedance spectroscopy method for evaluation of body cell water compartments

The traditional Cole or CFC basic model might offer too coarse estimations in personalized haemodialytic treatment. To take advantage of the full information content offered by BIS instrumentation the traditional CFC model can be extended into a more convenient model: the Extended CFC (ECFC) model. The ECFC model is used to fit raw bioimpedance measurements to increase the overall estimation accuracy of Resistance and Reactance terms. An experimental comparison between CPC, ECFC model simulations, and experimental data is presented. Experimental results show that higher accuracies (at least a tenfold improvement) over the traditional CFC model are easily achieved.
