Fig. 7From: Machine learning approach for predicting post-intubation hemodynamic instability (PIHI) index values: towards enhanced perioperative anesthesia quality and safetyFeature importance of 13 features in the ETR model. The importance values of the features sum to 1 with higher value indicating more important feature. The error bars represent the double standard deviation of the importance values obtained from 10-fold cross-validation. Fentanyl, Lidocaine, Propofol, and Rocuronium represent the converted doses of drugs at initial infusion.
