Bioimpedance Spectroscopy for Fluid Changes in Hemodialysis Patients

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study analyzes raw impedance measurements from BIS devices to see if they accurately reflect changes in body fluid status during dialysis. It compares data across multiple BIS devices and examines correlations with absolute blood volume, blood pressure, and weight changes over three consecutive dialysis sessions. The goal is to determine if BIS-derived metrics can reliably estimate fluid shifts in both center and home dialysis settings. The study also explores consistency of impedance metrics across devices and days in patients with and without fluid retention. Home versus center dialysis comparisons aim to identify potential practical implications for clinical practice.
