摘　　要：目的:研究脉搏波速与人体血压是否具有准线性相关性。方法:采集人体不同生理状态下的脉搏波速与对应血压数据,利用最小二乘法的原理拟合得到拟合曲线和拟合参数。结果:从拟合曲线和拟合参数中发现脉搏波速与血压具有准线性相关性,且拟合参数因人而异。结论:可以利用脉搏波速间接推测人体血压,达到连续血压的测量。Objective To determine if there is quasi-linear correlation between pulse wave velocity and blood pressure.Methods The data on pulse wave velocity and blood pressure in different physiological conditions were acquired,and the fitting curve and parameters were obtained by lease square method.Results The quasi-linear correlation between pulse wave velocity and blood pressure was found,and the fitting parameters of persons were different.Conclusion Pulse wave velocity can be used for indirect blood pressure measurement,and then the continuous blood pressure measurement can be realized.
