摘要
目前可穿戴式无创血压监测设备大多采用光电容积脉搏波描记法(PPG)信号进行血压监测,然而在运动过程中,PPG信号极易受运动伪影(Motion Artifacts)影响,从而大幅降低血压监测的准确性。近年来,基于PPG信号的运动过程血压实时估计成为研究热点。主要介绍PPG信号抗运动伪影技术研究进展,阐述PPG信号原理及噪声来源,并对现有PPG信号去噪算法原理与优缺点进行比较,最后分析运动伪影去除技术存在的问题及未来发展趋势。
Currently,wearable non-invasive blood pressure monitoring devices are mostly based on photoplethysmography signals.However,during the movement,the PPG signal is highly susceptible to motion artifacts,and the existing motion artifacts seriously interfere with the accuracy of blood pressure monitoring.In recent years,real-time estimation of blood pressure based on PPG signals has become a hot topic in current research.This paper mainly studies the research progress of PPG signal anti-motion artifact technology.The principle of PPG signal and the source of noise are expounded,and the principle,advantages and disadvantages of the existing PPG signal denoising algorithm are analyzed and compared.Finally,the problems existing in the motion artifact removal technology and the future development trends are analyzed.
