Blood Pressure Imager

This project aims for developing a novel continuous automatic noninvasive Blood Pressure (BP) measurement system which can take advantage of both the oscillometric and auscultatory methods of BP measurement. Such hybridization inherently makes the device more accurate than commonly available intermittent automatic oscillometric BP measuring devices which often provide wrong estimation of BP. The device is configurable to both desktop and wearable versions. The desktop version of the device was tested on a mock circulatory loop comprising of an artificial heart pump and arterial branches. Then it was used for estimating blood pressure of different animal models. The wearable version of the device is getting tested and further improved for its accuracy in estimating BP based on radial arterial pulse imaged from the skin surface of human wrist.
