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 efficient and feasible method to
obtain the parameters of central aortic pulse wave noninvasively.
