Clinical task
Continuous EEG (cEEG) monitoring in the intensive care unit (ICU) is used to detect electrographic seizures in critically ill and comatose patients, including non-convulsive status epilepticus [1].
Standardized terminology and periodic/rhythmic pattern classification are required for reproducible interpretation and clinical decision-making [2].
| Parameter | Value |
|---|---|
| Channels | 21–32 |
| Sampling rate | 256–512 Hz |
| Montage | 10–20 |
| Recording time | continuous, 24/7 |
Equipment
The studies relied on long-term EEG recording with our amplifiers and electrode caps; early seizure detection after traumatic brain injury is associated with a worse outcome [3].
