Measuring fluid balance in end-stage renal disease with a wearable bioimpedance sensor.

ABSTRACT:

Background

Accurate assessment of fluid volume and hydration status is essential in many disease states, including patients with chronic kidney disease. The aim of this study was to investigate the ability of a wearable continuous bioimpedance sensor to detect changes in fluid volume in patients undergoing regular hemodialysis (HD).

Methods

31 patients with end-stage renal disease were enrolled and monitored with a sensor patch (Re:Balans^®) on the upper back through two consecutive HD sessions and the interdialytic period between. The extracellular resistance R_E was calculated from multi-frequency bioimpedance measurements and was hypothesized to correlate with the amount of extracted fluid during dialysis.

Results

Only HD sessions with a positiv
