Abstract

Changes in peripheral arterial radius are tracked using non-invasive sensors and a simple local model for artery and tissue behavior. Sensing is performed using a conventional pulse plethysmograph and a custom-built piezoelectric pressure sensor. A simple mechanical model is used to relate sensor outputs to peripheral artery pressure and radius, using only radial tissue deformation under an assumption of close proximity of the two sensors. Applying an extended Kalman filter to the model to track arterial radius as an augmented state results in estimates of local vascular resistance that track well with systemic vascular resistance (SVR) measured invasively for a swine test subject.
