Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Total GCS | 10 3–15 |
|---|---|
| Pupils unreactive to light | One unreactive (−1) |
→GCS-P9/15
- Severity：Moderate
- Formula：GCS − Pupil Reactivity Score (0/1/2)
| Total GCS | 10 3–15 |
|---|---|
| Pupils unreactive to light | Both reactive (−0) |
→GCS-P10/15
- Severity：Moderate
- Formula：GCS − Pupil Reactivity Score (0/1/2)
