Continuous electroencephalogram monitoring in the critically ill.

The use of continuous electroencephalogram (cEEG) monitoring in the intensive care unit is becoming more widespread, with improvements in data storage capability and networking and the increasing awareness of nonconvulsive seizures. Current and potential uses for this technology include seizure detection, ischemia detection, and prognostication. Nonconvulsive seizures are common in the critically ill, particularly those with acute brain injury and those who are comatose.
