摘要
光电容积脉搏波包含了人体丰富的生理、病理信息,对其进行实时监测可为临床研究和诊断提供科学的指导。开发了一套基于图形化虚拟仪器工程设计平台LabVIEW的光电容积脉搏波信号采集系统,可完成对该信号的实时采集、显示和数据存储。经过指端光电容积脉搏波信号的透射式采集实验,在LabVIEW前面板上准确显示出了该信号的波形,有助于对光电容积脉搏波进行深入分析。
Photoplethysmograph（PPG） includes abundant information of physiology and pathology. Real-time monitoring on it can provide scientific guidance for clinical research and diagnosis. A PPG signal acquisition system is introduced. This system is developed on an engineering design platform named LabVIEW, which is a virtual instrument based on graphic language. PPG signal acquisition system is used to collect, display and store data in real time. One experiment is carried out for this research, which gathers PPG signal from fingertip in transmission way. PPG waveform is exactly displayed on LabVIEW＇ s front-panel. These display results are helpful to analyze PPG in depth.
