(A) Boxplots represent the distribution of systemic rSO2 and aEEG bandwidth SD during the 6 hours before rewarming and demonstrate the median, 25th, 75th, 10th, and 90th percentiles with outliers. Systemic rSO2 SD was independent from the absolute rSO2 value (B), but the variability of aEEG bandwidth increased as bandwidth increased (C). aEEG = amplitude-integrated EEG; rSO2 = regional oxygen saturation.
