The new ReDS system for fluid management: The clinical application status and prospect.

Abstract

Volume assessment is a critical and challenging clinical skill, especially in cardiology, emergency departments, and intensive care units. The right heart catheterization is the only gold standard to evaluate the volume, and there is currently a lack of rapid, non-invasive, and accurate methods to quantify pulmonary congestion. The remote dielectric sensing system (ReDS) is a non-invasive technique based on electromagnetic energy, which can quantify the percentage of lung fluid concentration in the body within one minute. Although ReDS technology was created 10 years ago, it has been only in the past 3 years that ReDS technology has gradually become more widely used in the clinic. Many patients with heart failure, lung infections, and perioperative have benefited. The purpose of this article is to introduce the new technology of ReDS and its current clinical application and prospects. It is hoped that it can provide more research ideas for clinicians and provide basis for further research on more diseases.
