A brachial artery-based system for blood pressure pulse wave measurement and its signal filtering technique

Human blood pressure (BP) and its pulse wave has always been a popular topic since it’s bound up with the heart related risks. In this paper, we mainly focus on of brachial artery which is also widely used in measurement BP, hence constructed artery-based system by using multi-Windkessel model managed to generate reliable signal adjustable authentic human parameters. On basis, filtering technique was discussed. We mixed noises different amplitude frequency into original intentionally, then several filters’ performances were compared. The designed combined filter represented stable performance, had little error BP values, ensure stability reliability system.
