WebObjective: The bispectral index (BIS) is a complex EEG parameter which integrates several disparate descriptors of the EEG into a single variable. One of the subparameters incorporated in the BIS is the suppression ratio, quantifying the percentage of suppression during burst suppression pattern. WebApr 21, 2024 · Burst suppression is defined as an electroencephalography finding consisting of a continuous alternation between of high-voltage slow waves (burst) and periods of depressed electrical activity [ 10 ]. Only sparse information is available with respect to the pathophysiological cellular mechanism of its pattern.
