CALLE HERRANZ, Abel; CARVAJAL ALFONSO, Reniel  e  REGUEIRO-GOMEZ, Angel. Characterization of the whole-body electrical impedance in subjects with renal chronic diseases. EAC [online]. 2014, vol.35, n.3, pp. 1-15. ISSN 1815-5928.

^{This work shows the study and characterization of whole-body electric impedance measurement with a channel of development KIT (AD5933) and an arrangement of electrodes placed in the superior and inferior extremities in voluntary healthy peoples and with renal critical problems. The characteristics of measurement are analyzed with the study of a phantom developed at laboratory level, where is demonstrated the correspondence among the variability of the impedance with regard to the loss of the volume of the liquid stored, similar as dialysis process. We are carried out measurements in 17 voluntary people (men and women between 20 and 85 years), being analyzed the variability of the whole-body electric impedance in the interval from 5 up to 55 kHz. We observed the relationship among the differential average of whole-body electrical impedance measurement variability and their relation with the Dry Weight variable obtained before and later to hemodialysis process in different studied peoples.}
