Hybrid Adaptive Kalman Filter: Calibrating a Hemodynamic Model for Continuous Arterial Pressure Monitoring

Abstract

A Hybrid Adaptive Kalman Filter (HAKF), consisting of a continuous Standard Kalman Filter (SKF) and an intermittent Least Squares Parameter Estimator (LSPE), is proposed to calibrate the hemodynamic model for continuous arterial pressure monitoring. Simulations of the HAKF using a classic Windkessel model are carried out to prove the principle of the proposal.
