The Bispectral Index or" BIS" is a single number, composed from different EEG features,
using multivariate statistical methods. It was designed for monitoring the depth of hypnosis
during anaesthesia and sedation. Empirically derived from the EEGs of more than 5,000
anaesthetised patients, the BIS reflects the effect of anaesthetics on the brain. Unlike
univariate measures, such as Spectral Edge Frequency or Median Frequency, the Bispectral
Index is drug independent and changes with increasing doses of hypnotics in an almost …
