用示波法计算动脉顺应性的研究与实现

提出了一种运用示波法无创地检测动脉顺应性的方法.研究了弹性腔理论,并分析了弹性腔与示波法的结合.总结出一种用于计算动脉顺应性的方法同时介绍其在临床应用中的使用效果.与传统的水银血压计进行比较,得到收缩压(SBP)相关性为r=0.918 5(P<0.001),舒张压(DBP)相关性为r=0.899(P<0.001).与超声多普勒诊断仪诊断结论进行比较,得到相关性为r=-0.820 9(P<0.01).这证明血压参数与动脉顺应性诊断结果的有效性,说明动脉顺应性是心血管临床检查的一个重要生理指标.从而使示波法可以应用于更多的心血管参数的检测.

Research and Realization of Calculating Artery Compliance Using Oscillometric Method

This paper presents a method that can non-invasively detect artery compliance using oscillometric method.There are also researches about Windkessel theory,and analysis of the combination of Windkessel and oscillometric method.Then the authors summarize a method to calculate artery compliance and introduce the clinical effect in the hospital.Compared with traditional sphygmomanometer,they get the pertinence of SBP is r=0.918 5(P<0.001).And the pertinence of DBP is r=0.899(P<0.001).Then it is compared with ultrasonic method,the pertinence of compliance is r=-0.820 9(P<0.01).This proves that the diagnose of blood pressure and artery compliance is effective and artery compliance is an important index in cardiovascular clinical measurement.So this paper makes the oscillometric method to be applied to wide ranges in calculating cardiovascular indexs.
