基于肱动脉的中心动脉压力波无创检测仪
Non-Invasive Detector of Central Aortic Pulse Wave Based on Brachial Pulse Wave
摘要
Abstract
Objective To adopt the transfer function method to estimate the central aortic pressure wave through peripheral brachial pulse wave, and to estimate the main parameters of the hemo-dynamics of the central artery in combination with the heart sound and ECG signals. Methods Central aortic pressure wave is essential to the analysis of the function of cardiovascular systems, but it cannot be measured noninvasively. In this paper, the Individualized Transfer Function (ITF) model of the vascular system from the brachial artery to the central artery is established for each individual. Then the individual models are integrated into a Generalized Transfer Function (GTF) model. Results By means of clinical laboratory evaluation and the comparison between estimated central aortic waveform and the invasively measured central artery waveforms, it is found that the use of the transfer function method can well reconstruct the central artery pressure waveform, and its parameters are estimated accurately. Conclusion This paper provides an efifcient and feasible method to obtain the parameters of central aortic pulse wave noninvasively.关键词
