Abstract

The goal of this chapter is to provide a training module for residents, neurophysiology fellows, neurocritical care fellows, nurses, EEG technologists, and any other non-neurophysiologists interested in evaluating bedside quantitative EEG (QEEG). Due to the increasing utilization of continuous EEG (cEEG) monitoring in intensive care units (ICUs), large volumes of EEG data are being generated. To assist with evaluation of large amounts of cEEG data, QEEG software programs are frequently employed. While raw EEG interpretation is performed by neurophysiologists, QEEG software provides a compressed and simplified view of the raw EEG signals, potentially allowing for evaluation by non-neurophysiologists. QEEG software can be seen running at the bedside in many ICUs. This chapter will be limited to the basics of QEEG trends for seizure recognition and artifact recognition. While there is ongoing research evaluating the performance of QEEG for other purposes (ischemia detection, evaluation of depth of burst suppression, prognosis in hypoxic-ischemic encephalopathy, etc.), the majority of current clinical QEEG utilization is for seizure detection.
