The X axis denotes the dates during this QI project, scaled monthly. The Y axis represents unplanned extubation events per 100 non-tracheostomy ventilation days. The green dashed line represents the center line (CL), and the red fine dotted line represents the upper control limit (UCL), whereas the green solid line represents the target goal for the QI project (<1 event per 100 ventilation days).
