Monitoring of body fluid in patients with chronic heart failure using Bioimpedance - Spectroscopy

Abstract

Patients with chronic heart failure (CHF) often suffer from the formation of edema within their body. To monitor the appearance of such edema in lung and limbs as early as possible would improve the medical treatment fundamentally. Bioimpedance-Spectroscopy is a non-invasive, easyto-implement measurement method that allows determining the water content of a patient. However, stable long term measurements are difficult to perform and so the optimal measurement conditions have to be defined precisely. In the past, a lot of work was focused on the development of the optimal measurement setup that allows stable and reproducible longterm monitoring of edema. Based on these investigations, a measurement protocol was developed and within this study, case reports shall be presented in which five patients suffering from acutely decompensated CHF were monitored during their complete medical treatment in the clinic. Every day, the whole body-and thoracic impedance were measured to monitor the progress of edema in the limbs and lung, respectively.

Utilization of Bioimpedance Spectroscopy in lieu of Invasive Monitoring for Monitoring Fluid Overload (Preprint)

“…These end-spectrum frequencies allow for individualized information specific to the extracellular and total-body fluid with increased accuracy and without the need for normalized population-specific algorithms. [8,9] On August 18th, the patient's diastolic PA pressure decreased to 11 mmHg from a previous measure of 13 mmHg (August 16th). Because of his fatigue coupled with objective data, it was decided he was dehydrated.…”

The utility of novel non-invasive technologies for remote hemodynamic monitoring in chronic heart failure

“…Bioimpedance spectroscopy has emerged as a potential method to detect subtle changes in thoracic fluid content HF patients [24,25]. A feasibility study using the BIM sensor for home TM has been conducted, where it was shown to predict episodes of hospitalization for worsening HF [SCHAUERTE P, UNPUBLISHED DATA].…”

“…Although the additional body signals relevant in assessing and improving overall human body (workers') health conditions today might be used trough: artificial cochlea, artificial retina, camera pill, carbon dioxide sensor, visual sensor, bio-impedance spectroscopy, chipped sweatbands, etc. [17][18][19][20], for the purpose of this study, the attention will be put to the firstly listed ones.…”
