E — Eye opening
V — Verbal response
M — Best motor response
E4 V5 M6 = total
15
Range 3 (minimum) to 15 (maximum)
GCS 15 — no impairment on this scale
Maximum score indicates full eye, verbal, and motor responses as scored. Still interpret in clinical context.
Not for intubation or sedation decisions by itself
Intubated patients may need a modified verbal score; sedatives and paralytics alter examination. Use structured neuro checks and protocols from your institution.
From spontaneous opening down to no response, reflecting arousal and brainstem-mediated reflexes in context of facial trauma and swelling.
Orientation and language content decline through confused speech, word salad, sounds only, to no verbal output—when testable.
Command following and purposeful movement progress through withdrawal and abnormal posturing patterns to no motor response.
15 = E4 + V5 + M6. Teaching bands: 13–14 mild, 9–12 moderate, 3–8 severe—always with clinical correlation and trends.
You choose one response per domain. The tool adds the three subscores and maps the sum to a short severity description used in many textbooks. It does not chart “NT” verbal scores or pediatric modifications—use paper or the EHR when those apply.
Pair with MAP when perfusion pressure is part of the same resuscitation picture.
