Abstract

Non-contact, non-invasive monitoring of hemodynamic parameters has long been deemed to be important to medical monitoring in a variety of environments. Radio Frequency Impedance Interrogation (RFII) measures hemodynamic function via resonance frequency coupling to a hydrophilic protein molecule. We examined the use of RFII for hemodynamic monitoring of human subjects during Lower Body Negative Pressure (LBNP) and physiological hemodynamic maneuvers using valsalva and orthostatic position changes in this small pilot study. Results demonstrate a high degree of correlation between stroke volume waveform amplitude (R 2 0.92) and RFII derived R-R interval (R2 0.99) and classic electrocardiogram (ECG). These results suggest that RFII may be of great utility in the pre-hospital triage setting and for in-hospital patient monitoring.
