A noninvasive estimation of central blood-pressure is required by the researchers or the medical practitioners in the cardiovascular treatment. In this study, first of all, a cardiovascular simulator based on the electrical circuits is described based on the model based approach and then, the representation of aorta model as a pressure transfer function is shown. This representation accelerates the simulator and then, makes it possible to estimate the central blood-pressure from a wearable gouge measurement in a real-time way. The system consisting of a main station, gateways and wearable blood-pressure gauges using one-board microcomputer is actually implemented. The functions and performances of the system are experimentally evaluated and the obtained results show the feasibility of central blood-pressure estimation and the localization of some examinees having wearable gauges with the practical accuracy and speed.
