Methodology · worked example, guidelines & full notes
Only moderate accuracy for VAP.
When to use
Adjunct to clinical judgement in suspected VAP.
How it works
Temperature, WBC, secretions, PaO₂/FiO₂, chest radiograph and culture — each 0–2. > 6 suggests pneumonia.
Key points
- Only moderate accuracy for VAP.
- Combine with microbiology and clinical course.

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.
| Temperature | 38.5–38.9 (1) |
|---|---|
| WBC (×10⁹/L) | < 4 or > 11 (1) |
| Tracheal secretions | Non-purulent (1) |
| PaO₂/FiO₂ | > 240 or ARDS (0) |
| Chest radiograph | Diffuse/patchy (1) |
| Tracheal aspirate culture | Moderate/heavy growth (1) |
→CPIS5/12
- Interpretation：≤ 6 — pneumonia less likely
- Note：CPIS has only moderate accuracy for VAP; use alongside clinical judgement and microbiology, not as a sole criterion.
| Temperature | 36.5–38.4 °C (0) |
|---|---|
| WBC (×10⁹/L) | 4–11 (0) |
| Tracheal secretions | None (0) |
| PaO₂/FiO₂ | > 240 or ARDS (0) |
| Chest radiograph | No infiltrate (0) |
| Tracheal aspirate culture | None/light growth (0) |
→CPIS0/12
- Interpretation：≤ 6 — pneumonia less likely
- Note：CPIS has only moderate accuracy for VAP; use alongside clinical judgement and microbiology, not as a sole criterion.

FAQ
Frequently asked questions
- What are the limits and cautions when using Clinical Pulmonary Infection Score (CPIS)?
- For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
- Does Clinical Pulmonary Infection Score (CPIS) upload patient data? Where is it calculated?
- 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 Clinical Pulmonary Infection Score (CPIS) calculated in practice? Can you show a worked example?
- Inputs: Temperature 38.5–38.9 (1), WBC (×10⁹/L) < 4 or > 11 (1), Tracheal secretions Non-purulent (1), PaO₂/FiO₂ > 240 or ARDS (0), Chest radiograph Diffuse/patchy (1), Tracheal aspirate culture Moderate/heavy growth (1) → Result: CPIS 5 /12（Interpretation: ≤ 6 — pneumonia less likely, Note: CPIS has only moderate accuracy for VAP; use alongside clinical judgement and microbiology, not as a sole criterion.） Inputs: Temperature 36.5–38.4 °C (0), WBC (×10⁹/L) 4–11 (0), Tracheal secretions None (0), PaO₂/FiO₂ > 240 or ARDS (0), Chest radiograph No infiltrate (0), Tracheal aspirate culture None/light growth (0) → Result: CPIS 0 /12（Interpretation: ≤ 6 — pneumonia less likely, Note: CPIS has only moderate accuracy for VAP; use alongside clinical judgement and microbiology, not as a sole criterion.）
