Benefits of technology

The patent text describes a method for analyzing physiological parameters using wavelet transforms. This method involves processing a physiological signal, such as a pulse oximeter, to determine various physiological parameters. The use of wavelet transforms can provide a more complete analysis of the signal by looking at both time and frequency. This technique can be useful in monitoring the health of patients and providing better care for them.

Problems solved by technology

However, such analyses may not provide information that is discernable in the time domain.

Embodiment Construction

[0014]One or more specific embodiments of the present techniques will be described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

[0015]Present embodiments relate to determining information from a patient's physiological signal based on a processing and / or comparison of the physiolo...

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.
