Abstract: The acquisition method of radial pulse wave is easily influenced by human body’s activities. The transfer function method was applied to estimate radial pulse wave using finger pulse wave. After the window size and the order of the model were being analyzed, the transfer function FIR model between radial pulse wave and finger pulse wave was set up firstly. Then the test data were used to estimate the radial artery pulse wave and verify the accuracy of the proposed model. By analyzing ten subjects’ data acquired in ten days, the best waveform match between the estimated and the measured radial artery pulse waves were in the range from 70% to 92%. It is notable that using the transfer function method could estimate radial pulse wave from finger pulse wave. This method provided a new easy way for monitoring radial pulse wave.

Key words: radial artery pulse wave, transfer function, finger pulse wave, FIR model, best waveform match
