Portable EEG in the ICU: Why Bedside EEG Matters
Critically ill patients often have altered consciousness from sepsis, metabolic disturbance, brain injury or medication. In many of them, seizures continue without visible convulsions. Without EEG these non-convulsive seizures go unnoticed, so portable bedside EEG has become an important ICU tool.
Why EEG belongs in the ICU
- Non-convulsive seizures are well documented in critically ill patients with unexplained coma or reduced consciousness.
- Post-cardiac-arrest care. EEG helps assess brain function and guide prognosis together with other tests.
- Encephalopathy assessment. EEG patterns help separate metabolic, toxic and structural causes.
- Sedation monitoring. EEG gives an objective view of brain activity during deep sedation.
Advantages of bedside EEG
Moving an unstable, ventilated patient to an EEG lab is risky and slow. A portable EEG comes to the patient, cuts delays and allows repeat or prolonged recording.
What to look for in an ICU EEG machine
- Size and power. A compact, USB-powered amplifier like the NEUROCOMPACT 24 Channel EEG (650 g) runs from a laptop with no extra power brick.
- Fast setup. Electrode caps or pre-gelled systems and real-time impedance checks.
- Artifact management. ICUs are electrically noisy, so good filtering and high CMRR matter.
- Long-recording capability. Continuous EEG for hours, with event marking.
- Remote review. Digital files that the neurologist can review on another workstation.
Practical tips for ICU EEG
- Train a small team of nurses or technicians to apply electrodes quickly.
- Keep a dedicated EEG trolley with caps, paste and spare electrodes.
- Note medications, sedation and procedures as events in the recording.
- Unplug unnecessary equipment near the bed when possible to reduce noise.
