When to use
Assess and trend consciousness in trauma, stroke and the critically ill. Record the EVM components.
How it works
GCS = Eye(1–4) + Verbal(1–5) + Motor(1–6). Severity: ≤ 8 severe, 9–12 moderate, 13–15 mild.
Key points
- Always report components (e.g. E3V4M5), not just the total.
- Score the best response; if intubated, verbal = 1T.
- GCS ≤ 8 — consider a definitive airway.
