利用示波法原理测量血压的一种新方法

目的 利用示波法原理在波形特征法和幅度系数法的基础上提出一种系数差分比值法来间接测量血压。方法 计算出相邻脉搏波的幅度差值和它们的相对比值并利用优先法则在一定幅值范围内进行突变点的判断。结果 系数差分比值法能够解决将平均压附近的点误判为突变点的问题，能提高测量血压的准确性。结论 系数差分比值法能判断心血管病患者与正常人的差异性，能够对血压判别提供有效性和可靠性，对我国心血管病方面流行病学的调查、疾病预防、疾病早期发现都具有很大的意义。

A New Algorithm for Oscillometric Blood Pressure Measurement

Objective To find a new algorithm for oscillometric blood pressure measurement. Method A coefficient difference comparative method was proposed to measure the difference of adjoining pulse waves and their comparative ratios. And the turning point was judged by priority way in the range. Result The new method settled the problem of miscarriage of justice of the turning point a- round average pressure and improved the accuracy of blood pressure measurement. Conclusion It can detect difference between cardiovascular patients and normal persons. And it is effective and reliable in blood pressure measurement. It provides a convenient method for researching, preventing and epidemiological studies of cardiovascular diseases in our country.
