Fig. 2From: Integrated pulmonary index can predict respiratory compromise in high‐risk patients in the post‐anesthesia care unit: a prospective, observational studyIPI fluctuation during PACU stay. This graph shows the fluctuation of the IPI values of each group at every 5 min within 1 h after admission to the PACU. The means and 95 % CIs of the IPI values at every point is described on the continuous line and the dashed line connects the mean IPI values for every 5 min. The ends of the upper and lower whiskers represent the 95 % CIs.
