摘要
Abstract
Pulse wave is reported to have a correlation with blood pressure and character parameters of pulse wave, which can predict blood pressure indirectly. A new predictive model was proposed in this paper for continuous monitoring of noninvasive blood pressure. This study aimed to extract 14 parameters from the pulse wave signal in order to establish the multivariate linear model. The improved stepwise regression analysis algorithm was used to estimate the blood pressure in real time, and the data of six patients in the MIMIC database was used to validate the dynamic model. The experimental results indicated that the mean and variance of deviation of blood pressure estimation met the American Medical Device AAMI standard (5±8 mmHg), and the predicted blood pressure was significantly correlated with the extracted blood pressure values. The results show that the dynamic model established by 14 parameters of pulse wave can be used to predict continuous blood pressure with high accuracy.关键词
