Study temporarily paused.

This is a prospective cohort study for 50 patients admitted to the cardiac care unit requiring clinically-indicated diuretic therapy for congestive heart failure. The purpose of this study is to assess the role of non-invasive cardiac output monitoring (NICOM) with the Starling Fluid Management System (Baxter Medical, Deerfield, IL) in determining volume status in patients with acute decompensated heart failure requiring intravenous diuretic therapy.

Inclusion Criteria:

1. Diagnosis of congestive acute decompensated heart failure (preserved or reduced ejection fraction) requiring clinically indicated IV diuresis
2. Admission to coronary/cardiac intensive care unit or cardiac step down unit
3. Able to provide written informed consent
4. Anticipated need for IV diuretics > 24 hrs

Exclusion Criteria:

1. Prisoner, pregnancy or post-partum stage, or age < 18 years
2. Known allergy to sensory material or gel
3. End stage renal disease or need for CRRT
4. Inability or contraindication to do a passive leg raise with both extremities (i.e., balloon pump, impella, spinal injury, amputation)
5. Other situation that might increase subject risk, interfere with study procedures, or confound study findings based on the opinion of the clinician/investigator
6. Inability to provide informed consent

• Adults age > 18
• Decompensated heart failure requiring clinically-indicated intravenous (IV) diuresis
• Admission to the cardiac care unit (CCU) or the step down unit (SDU)
• Ability to perform a passive leg raise (PLR)
