摘　　要：为了提高振动法血压测量的准确性，提出了一种基于心电R波与血压振动波之间相关性，识别振动信号的一种抗干扰方法一R波相关法，结合振动波形特征识别，该方法可有效地提取信号，消除干扰影响。该算法已在16位8098单片机上实现，本文同时给出了程序的详细流程图。To improve the accuracy of oscillometric blood pressure measurement , an artifact rejection methodfor oscillations detection called R wave-relative method was,developed. It was mainly based on the correlation between ECG R wave and oscillation. Combining with identification of oscillation characteristics this method candistinguish valid signals from interference. This algorithm has been implemented in 8098 microcontroller. Itsprogram flowchart has also been presented in this paper.
