GCS Result
Summary
The Glasgow Coma Scale (GCS) is a standardized neurological assessment tool used to objectively evaluate a patient's level of consciousness. It scores three components — Eye opening (1–4), Verbal response (1–5), and Motor response (1–6) — for a total ranging from 3 (deep unconsciousness) to 15 (fully alert). GCS is widely used in emergency medicine, trauma care, and intensive care units.
How it works
- Select the best Eye Opening response observed, scored 1 to 4.
- Select the best Verbal Response, scored 1 to 5.
- Select the best Motor Response, scored 1 to 6.
- The tool sums the three subscores into a total GCS of 3 to 15 and classifies severity as Mild (13–15), Moderate (9–12), or Severe (3–8).
Use cases
- Initial neurological assessment of trauma patients in emergency settings.
- Monitoring changes in a patient's conscious state over time in the ICU.
- Triage decisions for head injury severity in pre-hospital care.
- Communicating level of consciousness consistently across clinical teams.
- Predicting outcomes and guiding treatment intensity for brain injury patients.
