Detection of Patients With Abnormal Water Distribution Based on Bioelectrical Impedance Analysis (BIA)

The aim of this clinical investigation is to prove that the seca mbca detects dialysis patients with abnormal water distribution correctly. Abnormal high water distribution is defined as more than 2 liters of Total Body Water (TBW) above a normal value range. TBW and Extra Cellular Water (ECW) are calculated with prediction equations for healthy subjects generated in BCA-01. The results are compared with TBW and ECW ascertained by dilution methods as standard reference methods. The Bioelectrical Impedance Analysis (BIA) method should be evaluated to the accuracy of the absolute measurement of the volume state of dialysis patients (euvolaemic and hypervolaemic) based on a single measurement.
