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.
| BUN ≥ 25 mg/dL (urea ≥ 8.9 mmol/L) | No (0) |
|---|---|
| Altered mental status | No (0) |
| Pulse ≥ 109 bpm | No (0) |
| Age ≥ 65 years | No (0) |

- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is BAP-65 Score (COPD Exacerbation Risk) calculated in practice? Can you show a worked example?
- Inputs: BUN ≥ 25 mg/dL (urea ≥ 8.9 mmol/L) No (0), Altered mental status No (0), Pulse ≥ 109 bpm No (0), Age ≥ 65 years No (0) → Result: BAP-65 0 /4（Class: Class I, Map: 0→I · 1→II · 2→III · 3–4→IV） Inputs: BUN ≥ 25 mg/dL (urea ≥ 8.9 mmol/L) Yes (1), Altered mental status Yes (1), Pulse ≥ 109 bpm Yes (1), Age ≥ 65 years Yes (1) → Result: BAP-65 4 /4（Class: Class IV, Map: 0→I · 1→II · 2→III · 3–4→IV）
