Evaluation of the EasySense System in Congestive Heart Failure

Across the globe, Congestive Heart Failure (CHF) continues to be the leading cause of mortality and hospitalizations in the 21st century. Despite advancements, prognosis often remains poor and mortality high. Congestive Heart Failure diagnoses are often characterized by frequent hospitalizations and re-admissions, and early detection of pulmonary edema, a chief characteristic of worsening heart failure, may have positive implications in patients' quality of life and frequency of hospitalizations. The EasySense device is a non-invasive device designed to measure lung fluid in patients with CHF. Similar to ultrasound technology, the device uses radiofrequency waves to assess fluid status. The device is placed on the bare skin of the chest and held in place for approximately 60 seconds to obtain a reading.

This study seeks to evaluate the efficacy of the EasySense system in measuring lung fluid volume. Seventy-five patients are sought for enrollment. Patients will be enrolled during their hospital stay, and will be asked to maintain daily EasySense measurements, in addition to other measurements, for thirty days post-discharge.
