Abstract :
The blood pressure signal is weak nonstationary biomedicine signal. Wavelet analysis is used to pick up the character of blood pressure signal for useful information and the truth of the oscillation amplitude of artery oscillation curve is reckoned by fuzzy inference method. Sequentially, the exact relation between the cuff pressure and the oscillation amplitude is developed and this relation is fitted with recursive least square method. Finally the systolic pressure and the diastolic pressure are calculated with the wave amplitude threshold method. With wavelet analysis and fuzzy inference method, the interference resulted from cardiovascular disease or movement on measuring is effectively decreased and the accuracy of blood pressure measurement is improved
