一种间接测量人体血压值的新方法

现有的脉搏血流参数检测仪需要事先测量人体血压,并且操作不方便,针对这一问题,提出了一种获取人体动脉血压值的新方法.该方法基于动脉血压与光电容积脉搏波特征参数的相关性理论,对特征参数与动脉收缩压和舒张压进行相关性分析,从而获得与收缩压及舒张压相关性较大的几个特征参数;然后利用线性回归的方法得到动脉血压和这几个特征参数的方程,依此求出人体的动脉血压值.该方法同传统测压方法相比,测量方便,可被应用到无创光电检测仪中,具有更广阔的应用前景.

A New Method of Measuring Blood Pressure Indirectly

Existing detectors for pulse flow parameters can be used only after blood pressure measurement and their operation is inconvenient.Thus a new method was proposed for measuring the human body arterial blood pressure values.Based on the relationship between arterial blood pressure and the characteristic parameters of the photoelectric volume pulse waves,correlation analysis between the parameters and arterial systolic and diastolic blood pressures was performed to determine which parameters strongly correlate to the arterial systolic and diastolic blood pressures,with the dependence of arterial blood pressure on these parameters obtained by linear regression,and human blood pressure was thus indirectly obtained.Compared with the conventional methods,the proposed one is more convenient,can be applied to non-invasive optical detectors and has more potential applications.
