Abstract

Tonoarteriography (TAG), the cuffless and continuous arterial blood pressure measurement technology, is essential for the monitoring of cardiovascular diseases and hypertension. In this work, a method using a 3-axis accelerometer for TAG calibration is explored based on the hydrostatic effect of the peripheral artery. The accelerometer linked with a finger-based blood pressure probe, an analogue processing unit, and a real-time output display were set up in our lab for the TAG measurement. With the arms raised above, at or below the heart level, the effects of hydrostatic pressure on the TAG signals were examined using the accelerometer’s X, Y, and Z axises as references. The preliminary results of this study showed a corresponding variation in TAG signals to hydrostatic changes. Thus, the accelerometer for automatic cuffless calibration, combined with a peripheral-mounted BP sensor configuration, could be potentially used for unobtrusive and continuous BP/TAG measurement.
