In this article, the authors focus on the use of the bispectral index score (BIS) for determining hypnotic effect of sedative drugs and anesthetics. They state that high BIS value results from high electromyography (EMG) activity. They also report two cases in which BIS values are very high in cardiac surgery patients during deep hypothermic circulatory arrest (DHCA).
