A photoplethysmograph (PPG) is a simple medical device for monitoring blood flow and transportation of substances in the blood. It consists of a light source and a photodetector for measuring transmitted and reflected light signals. Clinically, PPGs are used to monitor the pulse rate, oxygen saturation, blood pressure, and blood vessel stiffness. Wearable unobtrusive PPG monitors are commercially available. Here, we review the principle issues and clinical applications of PPG for monitoring oxygen saturation.
光电容积脉搏波描记仪(PPG)是一种用于监测血液流动和血液中物质运输的简单医疗设备。它由一个光源和一个用于测量透射光和反射光信号的光电探测器组成。在临床上,PPG用于监测脉搏率、血氧饱和度、血压和血管硬度。可穿戴式无创PPG监测仪已在市场上有售。在此,我们综述了PPG监测血氧饱和度的原理问题及临床应用。
