Design and Realization of Hardware for Measurement of Hemodynamic Parameters
This paper presents the design and realization of the hardware for measurement of hemodynamic parameters.The aim of the work has been to develop the hardware for sensing of biological signals such as the oscillometric pulsations in armcuff and in wrist cuff,the photoplethysmography (PPG) signal and the electrocardiography (ECG) signal.The selection of signals allows a determination of selected hemodynamic parameters,which are important for primary screening of atherosclerosis,for example the pulse wave velocity (PWV) or the arterial stiffness index (ASI).The hardware is designed for measuring biological signals both during the increasing of pressure in the arm cuff and during the decreasing of the pressure.The measuring of oscillometric pulsations in the cuffs during the increasing of the pressure eliminates the artefacts caused by deformation of the arm tissues.The design and realization of the hardware is described in this paper.The paper includes the example of the measured signals and the short description of the initial signal database which has been created during verification of hardware.The paper presents the basic idea of primary screening of atherosclerosis using the selection of hemodynamic parameters in advance.
