Hemodynamic Monitoring During Hemodialysis Using Bioimpedance: A Comparison of Changes in Resistance Between Different Body Segments.

ABSTRACT:

Introduction

Prevention of hemodynamic complications during hemodialysis remains challenging. Although whole body bioimpedance is well established in fluid status assessment, its use for dynamic or continuous recordings is limited. A segmental approach may serve this purpose better. This study investigates which body segment is best targeted to measure bioimpedance for hemodynamic monitoring.

Methods

In this observational study, serial bioimpedance measurements were conducted on the whole body, lower leg, upper arm, and thorax of 15 patients during two hemodialysis sessions. The resistance component of bioimpedance was used to investigate the relationship with changes in volume and systolic blood pressure (SBP).

Findings

Predialysis to postdialysis changes in relative
