Electric Circuit Model and Thermo-Hue Hemodynamic Analysis for Non-Contact Blood Pressure Measurement

Abstract

Hypertension is a main factor of lifestyle diseases, and monitoring daily blood pressure (BP) could help prevent these diseases. To monitor BP daily, non-contact methods have been developed, but these methods are difficult to implement because they are used in specific areas. Here, an electric circuit model, as a novel model for BP estimation, was constructed by applying thermo-hue hemodynamic analysis (THHDA). Resultantly, the systolic blood pressure (SBP) estimated by the model could grasp characteristics of varied BP in the Valsalva maneuver, and the root mean squared error (RMSE) between estimated and measured SBP was as low as 17.571 mmHg.
