Weaning from mechanical ventilation: Feature extraction from a statistical signal processing viewpoint |
Abstract | ||
|---|---|---|
Clinicians' decision for mechanical aid discontinuation is a chal- lenging task that involves a complete knowledge of a great number of clinical parameters, as well as its evolution in time. Respiratory patternvariability appears asa useful extubation readiness indicator, and thus can be used as an informative feature in a statistical pat- tern recognition framework. Reliable assessment of this variability involves a set of signal processing techniques that should be care- fully evaluated for statistical validity. This paper evaluates different variability extraction techniques aimed to build a Bayesian classifier for weaning readiness decision. As a conclusion, Sample Entropy is selected as the best performance extraction method. By calcu- lating it over tidal volume signals, and with mean respiratory rates as additional input patterns, a 2D Bayesian classifier is constructed with principal component analysis selection. The obtained misclas- sification probability (Pe = 0.2141) is acceptable if compared with performance of single feature classifiers. |
