| Case | Eye | Verbal | Motor | Total | Severity | Clinical Snapshot |
|---|---|---|---|---|---|---|
| Case A | 4 | 5 | 6 | 15 | Mild | Fully responsive and follows commands. |
| Case B | 3 | 4 | 6 | 13 | Mild | Opens eyes to speech with mild confusion. |
| Case C | 2 | 3 | 5 | 10 | Moderate | Responds to pain and localizes stimulus. |
| Case D | 1 | 2 | 4 | 7 | Severe | Minimal responsiveness with withdrawal only. |
| Case E | 1 | 1 | 2 | 4 | Severe | Very low responsiveness with extensor posturing. |
Glasgow Coma Scale Total = Eye Opening + Verbal Response + Motor Response
GCS = E + V + M
Eye range: 1 to 4
Verbal range: 1 to 5
Motor range: 1 to 6
Possible totals range from 3 to 15.
Severe: 3 to 8
Moderate: 9 to 12
Mild: 13 to 15

This page is designed for structured documentation and rapid score review. It helps standardize calculation, but it does not replace bedside assessment, airway evaluation, imaging, or specialist judgment.
1. What does the GCS measure?
It measures level of consciousness using eye, verbal, and motor responses. The combined score helps summarize neurological responsiveness in a standardized way.
2. What is the highest possible GCS score?
The highest score is 15. That reflects spontaneous eye opening, oriented verbal response, and obeying motor commands.
3. What score range is considered severe?
A total from 3 to 8 is commonly categorized as severe impairment. That range often requires urgent attention and close monitoring.
4. Can I use this for repeat assessments?
Yes. Serial scoring is useful because trends may matter more than one isolated score. Repeating the assessment can highlight improvement or deterioration.
5. Does this calculator replace clinical judgment?
No. The score is a structured aid. Real clinical decisions also depend on airway status, pupils, vital signs, imaging, context, and examiner judgment.
6. Why include export options?
CSV and PDF exports make it easier to save a result, share it with teams, attach it to notes, or use it in audit workflows.
7. What if a patient is intubated or sedated?
Document that limitation clearly in the notes. Clinical context can affect interpretation, and some response components may not be fully testable.
8. Why show a chart for only three components?
A visual chart quickly shows which component is driving the total. That makes handoffs, trend reviews, and documentation easier.
