Clinical implications of remote dielectric sensing system to estimate lung fluid levels

Published:August 08, 2022DOI:


      • Remote dielectric sensing (ReDS) is a non-invasive electromagnetic energy-based system to quantify lung fluid.
      • ReDS values have correlations with other pulmonary congestion-related modalities.
      • ReDS-guided management of congestive heart failure patients is the next concern.


      The reduction of pulmonary congestion is an essential clinical target in the management of chronic heart failure. This proves to be challenging given the lack of a gold standard method to quantify the degree of pulmonary congestion both quickly and non-invasively. Remote dielectric sensing (ReDS) is a non-invasive electromagnetic energy-based technology to quantify lung fluid levels as a percentage within minutes. This technique, due to its high negative predictive value, may be a useful tool particularly to rule out primarily cardiac causes of dyspnea in ambulatory patients when the values are normal. Further studies are warranted to establish ReDS-guided management of congestive heart failure patients.
