Patient Signal Filtering

摘要

Disclosed herein is a framework for facilitating patient signal filtering. In accordance with one aspect, the framework performs a signature cycle matching pursuit method to remove a first signal component from a combination patient signal and generate a first output signal. Sub-bandwidth filtering of the first output signal may be performed to remove a second signal component and generate a second output signal. The framework may further remove a third signal component from the second output signal to generate a third output signal. A signal of interest may then be reconstructed based on the third output signal.

主权项

1. A non-transitory computer readable medium embodying a program of instructions executable by machine to perform steps for signal filtering, the steps comprising:
receiving an electrophysiological signal; removing an electrocardiogram signal component from the electrophysiological signal by performing an electrocardiogram signature cycle matching pursuit method to generate a first output signal; eliminating noise from the first output signal to generate a second output signal by performing sub-bandwidth filtering of the first output signal; removing a respiration signal component from the second output signal to generate a third output signal; and reconstructing a blood pressure signal based on the third output signal.
