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.
减轻肺淤血是慢性心力衰竭管理中的一个重要临床目标。鉴于缺乏一种能够快速且非侵入性地量化肺淤血程度的金标准方法，这一目标颇具挑战性。远程介电传感（ReDS）是一种基于电磁能的非侵入性技术，可在数分钟内将肺液水平量化为百分比。由于该技术具有较高的阴性预测价值，当数值正常时，它可能是一种有用的工具，尤其有助于排除门诊患者主要由心脏原因导致的呼吸困难。有必要开展进一步研究以确立基于ReDS指导的充血性心力衰竭患者管理方案。
