This study evaluates the use of a wearable vest capable of non-invasively measuring lung fluid content in hospitalized patients with heart failure
Inpatient management of acute decompensated heart failure centers around the efficient relief of congestion with IV diuretics and vasoactive agents. For the majority of patients, non-invasive, clinical bedside tools such as jugular venous pressure, pulmonary auscultation and daily weights are used to estimate cardiac filling pressures and guide diuresis. However, these methods are subject to significant inter-observer variability and can be unreliable for various reasons. Furthermore, recent studies have shown that overt signs of clinical congestion correlate poorly with hemodynamic congestion…
Inclusion Criteria: * Patients hospitalized for acute decompensated heart failure requiring treatment with intravenous diuretics and/or IV vasoactive drugs * Patient has signed informed consent and has authorized use and disclosed health information * Patient is at least 18 years of age * Patient physically suitable for ReDS measurement * GFR\>25 * Initial ReDS Measurement \>35% Exclusion Criteria: * Patient characteristics excluded from approved use of ReDS system: height less than 155cm or greater than 190cm, BMI \<22 or \>39, chest circumference \<80cm or \>115cm , or flail chest * Evide…
ReDS measurements will be shared with the treating clinicians who can use the information to guide diuresis and determine the appropriate timing of discharge
ReDS measurements will not be shared with the treating clinicians, who will guide diuresis using standard clinical criteria
