Motor response
Brainstem reflexes
Respiration
When to use
Grade coma, including in intubated patients where GCS verbal cannot be tested.
How it works
Four components (Eye, Motor, Brainstem reflexes, Respiration) each 0–4; total 0–16. Lower scores indicate deeper coma.
Key points
- Usable in intubated patients (no verbal component).
- Captures brainstem reflexes and breathing pattern.
- Lower totals predict worse outcomes.
