1. A computer-implemented method of patient signal analysis, comprising:
- receiving, from a patient monitor, a patient signal data waveform;
generating, by a processor, a set of vectors directed from a common center to points of interest on the patient signal data waveform;
extracting, by the processor, one or more vector parameters from the set of vectors; and
determining, by the processor, one or more vector ratios based on the one or more vector parameters to monitor changes in the patient signal data waveform, wherein determining the one or more vector ratios comprises determining one or more unilateral ratios from the vectors or determining one or more bilateral ratios from the vectors.

Abstract
Disclosed herein is a framework for facilitating patient signal analysis based on vector analysis. In accordance with one aspect, a set of vectors is generated from a patient signal data waveform. The vectors may be directed from a common center to points of interest on the patient signal data waveform. The framework may further extract one or more vector parameters from the set of vectors, and determine one or more vector ratios based on the vector parameters to monitor changes in the patient signal data waveform.
