DETERMINATION OF A PHYSIOLOGICAL PARAMETER
First Claim
1. A method for generating a data library, comprising:
- acquiring a plurality of physiological signals associated with a physiological condition of a patient;
performing a continuous wavelet transform on each physiological signal to generate a respective wavelet transform product for each physiological signal; and
organizing the wavelet transform products so that the wavelet transform products may be searched using a current wavelet transform product derived from a current physiological signal.

Abstract
Methods and systems are provided for analyzing a physiological signal by applying a continuous wavelet transform on the signal and comparing the wavelet transformation to a library of wavelet signatures corresponding to one or more physiological conditions and/or patient conditions. A pulse oximeter system may relate the wavelet transformation with one or more of the wavelet signatures based on filters and/or thresholds, and may determine that the wavelet transformation indicates that the patient of the physiological signal has a physiological condition indicated by the related wavelet signature. In some embodiments, the pulse oximeter system may use previous analyses in a neural network to update the library. Further, non-physiological components of the wavelet transformation may also be identified and removed.
