Problems of ensuring the uniformity of blood pressure measurements

The problems of ensuring the unity of non-invasive blood pressure measurements are considered. It is shown that the artery and surrounding tissues of the body serve as a means of comparing the values of blood pressure and air pressure in the cuff, and that the metrological traceability of measurement results to pressure standards only partially determines the reliability of these results. The potential possibilities of the surface pulse wave method in comparison with the Korotkov tone method are estimated.
