bispectral index

Abbreviation: BIS
An electroencephalographic measure of the effect of sedative and hypnotic drugs on an anesthetized patient. It is used (along with clinical assessment of the patient) to determine the level of central nervous system depression. The index ranges from zero (completely unresponsive to stimulation) to 100 (awake and alert). At levels below 60, most patients are adequately sedated for surgery.
