1. A system for patient signal analysis, comprising:
- a multi-channel patient monitor configured to acquire first and second patient signal data; and
a computer system communicatively coupled to the multi-channel patient monitor, wherein the computer system includesa non-transitory memory device for storing computer readable program code; and
a processor in communication with the memory device, the processor being operative with the computer readable program code to perform steps includingsegmenting the first and second patient signal data into respective first and second regions of interest,extracting respective first and second waveform parameters from the first and second regions of interest, andgenerating one or more morphology indices based on the first and second waveform parameters to compare shapes of the first and second regions of interest.

Abstract
Disclosed herein is a framework for facilitating patient signal analysis. In accordance with one aspect, first and second patient signal data are received from a patient monitor. The first and second patient signal data may then be segmented into respective first and second regions of interest, from which respective first and second waveform parameters may be extracted. One or more morphology indices may then be generated based on the first and second waveform parameters to compare shapes of the first and second regions of interest.
