Heart Failure

Know your patient’s fluid volumes and track changes over time to identify the optimal fluid range for your patient.

ImpediMed SOZO HF-Dex Analysis for Heart Failure Objective Metric

Objective Measure of Fluid Volume

Heart failure (HF), also known as congestive heart failure or chronic heart failure (CHF), affects ~26 million people globally. Current monitoring technologies such as weight scales or implantable pulmonary artery pressure (PAP) monitors are either inaccurate or require invasive procedures.

The SOZO® Digital Health Platform with HF-Dex™ offers a fast, accurate, and non-invasive measurement of fluid burden to better monitor and manage heart failure patients at the point-of-care.

HF-Dex Analysis for Heart Failure

ImpediMed’s sophisticated BIS technology ensures high quality, objective fluid volume measurements, every time.

  • HF-Dex heart failure index provides a measure of fluid status
  • Total Body Water (TBW) volume accounts for all of the water in the body.
  • Extracellular Fluid (ECF) volume includes the water outside of cells.
  • Intracellular Fluid (ICF) volume includes the water inside of cells.
  • Weight

Fluid Volume and Heart Failure

Reduced cardiac function in heart failure patients leads to a buildup of extracellular fluid. The optimal fluid volume can vary from patient to patient and change with disease progression.

HF-Dex

  • Measure of fluid volume in heart failure patients: extracellular fluid as percent of total body water
  • Consistent and objective metric, free of inter-observer error
  • Tracks fluid retention and loss that are not visible with weight alone

Total Body Water

  • 60% of human body is water1
  • Varies based on age, gender, body size, and composition
  • Maintained by homeostasis
  • Impacted by normal weight gain or loss as well as disease conditions

Intracellular Fluid2,3

  • Majority of body water in healthy adults
  • Muscle contains ~75% water and makes up ~50% lean body mass
  • Decreases in ICF are associated with decreases in muscle mass

Extracellular Fluid4

  • Stored in intravascular and interstitial spaces
  • Reduced cardiac function in HF patients lead to fluid volume increase
  • Extent of ECF can vary from patient to patient and change with disease progression
