Novel Methods for Measuring Depth of Anesthesia by Quantifying Dominant Information Flow in Multichannel EEGs

Figure 5

Results of proposed indices and conventional indices averaged over 13 subjects for three infusion rates (error bar denotes the standard deviation over 13 subjects. A: before anesthetics infusion, B: increase in anesthetic concentration, C: steady state in anesthetic concentration, D: decrease in anesthetic concentration, and E: near ROC and recovery). (a) Results for infusion rate of 3 mg/kg/h, (b) results for infusion rate of 6 mg/kg/h, and (c) results for infusion rate of 12 mg/kg/h.
