The bispectral index is a statistically based, empirically derived complex parameter. It is a weighted sum of several electroencephalographic subparameters, including a time domain, frequency domain, and high order spectral subparameters. The BIS monitor provides a single dimensionless number, which ranges from 0 (equivalent to EEG silence) to 100.

WebThe bispectral index (BIS) is a monitoring modality that uses a processed electroencephalogram signal to quantify the depth of anesthesia or sedation. A BIS value of 100 (unitless scale) is considered complete alertness, 0 represents no cortical activity at all, and the range of 40 to 60 is believed to be consistent with general anesthesia. WebMonitor Recommended range for GA Notes; BIS™ 40–60: β ratio (related to activity in 30–47 Hz range) is component of upper range of index.
