METHOD AND SYSTEM FOR ANALYSING AND PROCESSING PHOTOPLETHYSMOGRAM SIGNALS USING WAVELET TRANSFORM ANALYSIS

摘要

A method of measuring physiological parameters, comprising: using a signal acquisition means to obtain a pulse oximetry signal; decomposing the pulse oximetry signal by wavelet transform analysis; identifying a primary band and a secondary band on a transform surface constructed by the wavelet transform analysis; and interpreting the secondary band to reveal information pertaining to the physiological parameters causing the primary band.
