Abstract

A radial artery and finger photoplethysmography (PPG) pulse wave velocity (PWV) noninvasive detecting instrument is designed. This instrument detects radial artery pulse wave and finger PPG pulse wave synchronously, and then radial-finger pulse wave velocity (PWV_rf) is computed. The hardware adopts two separate circuits to reduce interference between the coinstantaneous radial artery pulse wave detection and finger PPG pulse wave detection. Moreover, the software can store detection results for dynamic analysis. The instrument has the advantage of convenience. It is noninvasive and has good clinical value in the detection of PWV.
