Heatmap of the overall agreement between the depth-of-anesthesia
algorithms. The red boxes indicate the customary clinical depth-of-anesthesia
regions of burst suppression (0 – 20), deep hypnosis (20 – 40),
general anesthesia (40 – 60), mild/moderate sedation (60 – 80) and
awake (80 – 100). The red tramlines minimally bound these regions.
(A) Agreement of the BIS A-2000 native algorithm with the
ibis algorithm.
(B) Agreement of the BIS A-2000 native algorithm with the
ezibis algorithm.
(C) Agreement of the BIS A-2000 native algorithm with the
openibis algorithm.
