“…For all data types, the mean square errors (MSE) between the central-blood pressures of simulator and those of PTF are 2.0e-14, 2.4e-14, and 4.1e-14, and therefore, the accuracy is within a practical use [5]. The details of the data types are described [5].…”

“…In order to accelerate the parameter fitting, it is suggested that the aorta model, "T-Tube" block in Figure 3, is replaced by the corresponding transfer function, called a Pressure Transfer Function (PTF) [5]. The transfer function is commonly used in the analysis of systems such as single-input and single-output filters and its calculation is usually very fast.…”

“…This means that the central blood-pressure can be estimated from the radial blood-pressure by using the simulator. Therefore, the central blood-pressure measurement system consisting of a wearable IoT device (that is, a sensor), a network and a cloud sever on which the simulator is executed can be constructed [5]. A real-time and round-the-clock blood-pressure measurement is often required.…”

“…This paper gives a constitutive solution to this estimation problem, that is, an aorta model in the simulator can be represented by a Pressure Transfer Function (PTF) [5]. Using the PTF, the central blood-pressure calculation becomes simple and it is accelerated to the practical level.…”

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.
