Comparison of Two Electroencephalograms (EEG) Monitors in Patients Undergoing General Intravenous Anesthesia

Quantium Medical Company has an ElectroEncephalograph-based (EEG-based) algorithm with two outputs: qCON for unconsciousness and qNOX for anti-nociception. qCON, is designed to provide information about the depth of the hypnotic state, similar to that provided by the BIS™.
