3. Non-invasive blood pressure waveform artifact suppression
We now turn to a more classical application of wavelet methods: the processing of an electrophysiological signal. This application is more classical in that it uses a wavelet transform based on the application of a single wavelet, rather than on a basis constructed from a family of mathematically related wavelets. Once again, the choice of a wavelet with morphological characteristics appropriate to the physiological signal under consideration is crucial to the success of the application.
3.1 General description of the artifact removal problem
The blood pressure measurement system used in most patient monitors measures small fluctuations in pressure in a cuff applied to one of the patient's arms, to obtain systolic and diastolic pressure. Mean arterial pressure...
