Fig. 1From: Integrated pulmonary index can predict respiratory compromise in high‐risk patients in the post‐anesthesia care unit: a prospective, observational studyPredictors of RC in PACUs. Comparisons of the receiver operating characteristic curves for the initial IPI (A) and SpO2 (B) values as predictors of RC in PACUs. The AUCs of the IPI and SpO2 were 0.80 and 0.64, respectively. RC: respiratory compromise, PACU: post-anesthesia care unit, IPI: integrated pulmonary index, SpO2: oxyhemoglobin saturation measured by pulse oximetryBack to article page
