基于振动法和柯氏音法的无创血压测量值差异性研究

Study on difference of noninvasive blood pressure measurement method based on oscillometric and auscultatory

对无创血压测量仪测量值误差异性展开分析。用与各种血压测量技术进行比较的方法,着重分析了振动法无创血压测量和柯氏音听诊法。使用振动法无创伤血压测量监护仪和柯氏音听诊法对样本人群进行了血压测量,分析所得数据,结果表明,基于振动法和柯氏音法无创血压测量仪测量值差异小,准确性也比较好。同时,也展望了无创血压装置未来的发展方向。

This paper introduces and compares several blood pressure measurements, among which two noninvaslve blood pressure measurements based on oscillometric and auscuhatory methods are mainly compared. It also analyses the characteristics and advantages of oscillometric method as well as introduces a noninvasive blood pressure measurement monitor based on oscillometric. By using this monitor and a common auscultory method, we conducted a public survey. The result for statistical data analysis showed that the difference between oseillometric and auscuhatory methods are quite small, and the accuracy of them are both quite good .This paper also previews the future of the noninvasive blood pressure measurement
