Abstract

Baroreflex regulates arterial pressure by modulating ventricular and vascular properties. We investigated if the framework of circulatory equilibrium that we developed previously (Am J Physiol 2004, 2005) by extending the classic Guyton's framework is capable of predicting baroreflex induced changes in arterial pressure. In animal experiments, we estimated open loop transfer functions of baroreflexly modulated ventricular and vascular properties, synthesized baroreflex induced dynamic changes in arterial pressure using the estimated transfer functions and compared the predicted responses with measured responses. We demonstrated that the predicted baroreflex induced changes in arterial pressure matched reasonable well with those measured. We conclude that the framework of circulatory equilibrium is generalizable under the condition where baroreflex dynamically changes arterial pressure.
