摘要
阐述设计一种嵌入式生命体征检测系统,测量人体PPG信号,并进行软硬件滤波、特征提取和算法处理.提出一种从PPG信号中提取脉搏波传导时间的方法,将无创测量的血氧饱和度和血压显示在屏幕上.Bland-Altman一致性分析显示,数据均在95％置信区间内,说明系统在血氧饱和度、收缩压和舒张压检测上具有较高的准确性.
Abstract
This paper describes the design of an embedded vital sign detection system,which measures human PPG signals and performs software and hardware filtering,feature extraction,and algorithm processing.It proposes a method for extracting pulse wave conduction time from PPG signals,displaying non-invasive measurements of blood oxygen saturation and blood pressure on the screen.The Bland Altman consistency analysis showed that the data were all within the 95％confidence interval,indicating that the system has high accuracy in detecting blood oxygen saturation,systolic and diastolic blood pressure.
