A quantification method for radial artery pulsation device

Abstract

In this study we present a multi-step constant pressure pulse measurement system based on the technology and operating principles of electronic sphygmomanometer. We approach pulse diagnosis in a way that's comparable to pulse diagnosis practiced by traditional Chinese medicine (TCM) physicians, in particular where the administration of superficial, middle, and deep pressure were applied during pulsation measurement. We capture radial artery pulse signals as quantitative vascular pressure fluctuations (in mmHg) all the while pressure cuff step-up pressure over the measurement site, from 30mmHg to 180mmHg, using a 10mmHg step, and 10 seconds hold of constant pressure between the steps to capture pulse signals for respective pressures. We intend this work to lend TCM physicians a quantitative and visual supplement during a pulse diagnosis, and to enrich cardiovascular and clinical analysis applications from pulsation measurement.
