Abstract: Flow Mediated Dilation (FMD) is a non-invasive method for assessing vascular health. In this method, cuff occlusion is used to create reactive hyperemia and measure the following dilation of the brachial artery. Although many researches have been conducted in this area, there are still many debates about the method as the position of the cuff, the occlusion duration and related fiziological procedures. In this regard, an electrical model for circulation is implemented consisting of 63 segments for large and 30 for peripheral arteries.The resulting pressure and flow signals are presented which are close to What is expected according to the literature. Cuff occlusion is also added to this model as a variable resistor and the results are depicted and compared with real measurements. The provided platform will further be used to add the model of the involved physiological mechanisms and regulations.
