Brief summary

Quantium Medical Company has an ElectoEcenphalograph-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™.

Interventions
