Glasgow Coma Scale (GCS) Calculator
Score eye, verbal, and motor responses to assess level of consciousness (3–15).
Educational use only. Always interpret GCS with clinical context, sedatives, intoxication, and airway status.
How it works
The Glasgow Coma Scale (GCS) is a bedside tool used to quantify level of consciousness. It combines three components: eye opening (E), verbal response (V), and motor response (M).
Total score is calculated as E (1–4) + V (1–5) + M (1–6), giving a range from 3 to 15. When documenting, report component scores where possible (e.g., E3 V4 M6).
Common classification
Worked examples
Example 1: E4 V5 M6
Example 2: E2 V2 M4
Clinical safety note: Sedatives, paralytics, alcohol/drugs, language barriers, and intubation can affect scoring (especially verbal). Use trends and overall clinical assessment, and follow local documentation standards for “verbal not testable”.
