ZOLL HFMS is a non-invasive, patch-based device that uses novel radiofrequency technology for early detection of changes in pulmonary fluid levels, an increase in which is an early indicator of heart failure decompensation.
- Radar waves can be used to measure interstitial edema, an early sign of heart failure
- Changes in signal path delay and strength indicate changes in fluid
- Waves are highly modulated by tissue hydration, producing a very sensitive, robust measurement known as Thoracic Fluid Index (TFI)
ZOLL HFMS also records, stores, and transmits additional patient data that can be used to inform care plans, including heart rate, respiration rate, activity, posture, and heart rhythm (ECG).
