Glasgow Coma Scale (GCS)

Eye opening (E)1–4

Verbal response (V)1–5

Motor response (M)1–6

Intubated (verbal scored as 1T)Eyes closed by swelling (eye scored as 1C)

Components matter as much as the total. GCS 8 with E2 V2 M4 (eyes-to-pain, sounds, withdraws) is a different patient than GCS 8 with E1 V1 M6 (no eye, no verbal, obeys commands — possibly locked-in or sedated). Always document the breakdown, not just the total. The motor score is the most prognostic component and the most resilient to confounders.

GCS ≤ 8 is the airway threshold. Conventional teaching is that patients with GCS ≤ 8 lose protective airway reflexes and warrant definitive airway management (endotracheal intubation). Like all rules of thumb it has exceptions — sedated, post-ictal, or hypoglycemic patients may have low GCS but be expected to recover quickly. Clinical judgment integrates trajectory, cause, and other factors.
