iCVS—Inferring Cardio-Vascular hidden States from physiological signals available at the bedside
Fig 1
A schematic representation of the cardiovascular model.
The model is a serial circuit and contains one heart chamber which acts like a pump, organs, and arterial and venous compartments. Heart rate, contractility, vascular resistance and unstressed venous volume are affected by the baroreflex (Sb) which is determined by the arterial pressure, and by S which is an independent component that does not depend on the current physiological state. In addition, intra-vascular volume can change through Iex and the vascular resistance is also modulated by MSVR. Created with BioRender.com.
