Summary

The purpose of this study is to determine if the SNAP II electroencephalography (EEG) monitor accurately reflects changes in sedation level in outpatients undergoing surgery or procedures with sedation.

Conditions

• Sedation

Interventions

Type	Name	Description
OTHER	SNAP II EEG System	A portable EEG monitor (SNAP II EEG System, Everest -St. Louis) is unique in that it monitors both low frequency EEG signals (1-40 Hz), which are typically used, and high frequency EEG signals (80-420 Hz), which are not usually used, and calculates a derived EEG parameter (the SNAP Index). The SNAP Index ranges from 100 (completely awake) to 0 (no brain activity) and has been shown in a few studies to correlate with increasing sedation and loss of consciousness in human volunteers and patients receiving general anesthesia during surgery.
