Heart Failure

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

ImpediMed SOZO Objective Measure Fluid Volume

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
