Abstract :
An instantaneous blood pressure measuring system at the wrist based on the volume-compensation method is developed, and the characteristics and accuracy of the system are evaluated. Results of measurement indicated that, the radial artery could be completely compressed using the local pressurizing cuff, and the cuff-pressure controller is suitable for BP measurement in human. Also, the comparative measurements between the present system and the invasive blood pressure measuring device (direct method) indicated that, the results obtained from the two methods are well correlated not only in rest condition, but also in a stressful condition. Therefore, the system is capable of non-invasively measuring instantaneous blood pressure at radial artery.
