Responsiveness Index versus the RASS-Based Method for Adjusting Sedation in Critically Ill Patients

Figure 4

(a) Violin plot presenting the RI value change from 30 minutes before propofol bolus administration to the time of bolus administration (left) and the RI value change from the time of bolus to 30 minutes after the bolus (right). (b) Violin plot presenting the RI value change from 30 minutes before oxycodone bolus administration to the time of its administration (left) and the RI value change from the time of bolus to 30 minutes after the bolus (right). Cyan presents the RI group and magenta the RASS group. The violin plots present rotated data distribution; i.e., the wider the area is, the more samples are in the range. The thick black line indicates interquartile range, and the green circle is the median. In the RI group, propofol boluses were mostly administered to increasing RI values, and the RI values decreased during the following 30 minutes in most cases.
