脉搏波传导时间法检测血压算法的研究与实现
|
摘要
目的研究并实现用脉搏波传导时间法检测血压。方法利用对心电R波和脉搏波波峰的定位,计算脉搏波传导时间;利用检测方法结合监护仪检测血压采集大量数据,对脉搏波传导时间和人体血压数据进行统计分析。结果实现对心电R波和脉搏波波峰的定位,并计算脉搏波传导时间;利用统计结果进行血压估计,估计值与实测值误差在5 mm Hg,占比32.54%;误差在10 mm Hg以内的占比59.92%。结论定位方法的稳定性还需提高,血压估计算法的准确度还不够,后期将据此深入研究。
Objective To study and realize the method to detect the blood pressure by pulse wave transmission time(PWTT).Methods The PWTT was calculated by using the orientation of the electrocardiogram R wave and pulse wave peak. Statistical analysis was performed on the relationship between the PWTT and human body's blood pressure by using the detection method combined with the monitor blood pressure collecting a large amount of data. Results The orientation of the electrocardiogram R wave and pulse wave peak were realized, and the PWTT was calculated. Meanwhile, the blood pressure was estimated based on the statistical results. The proportion of the error of the estimated value and the measured values in 5 mm Hg accounted for 32.54% and in 10 mm Hg accounted for 59.92%. Conclusion The stability of the positioning method still needs to be improved. In addition, the accuracy of the blood pressure estimation algorithm is not enough, and further studies will be conducted in the future.
