Methodology · worked example, guidelines & full notes
Sputum purulence is the pivotal cardinal symptom — two symptoms only trigger antibiotics when purulence is one of them. (original synthesis · not guideline verbatim)
When to use
Use to decide whether antibiotics are indicated and to set the steroid course, controlled-oxygen target, and noninvasive ventilation threshold.
How it works
Antibiotics if all three cardinal symptoms, two including purulence, or ventilation needed. Prednisolone 40 mg/d × 5 days; SABA ± SAMA; oxygen SpO₂; NIV at low pH [pending update] or severe dyspnea.
Key points
- Sputum purulence is the pivotal cardinal symptom — two symptoms only trigger antibiotics when purulence is one of them. (original synthesis · not guideline verbatim)
- Controlled oxygen targets SpO₂ to avoid CO₂ retention in chronic hypercapnia.
- Pseudomonas risk factors shift empiric therapy to an anti-pseudomonal regimen with cultures.

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.
| Worsening dyspnea | Present |
|---|---|
| Increased sputum volume | Present |
| Sputum purulence | Present |
| Needs invasive or noninvasive ventilation | Yes |
| Arterial pH (optional) | 7.30 |
| Pseudomonas aeruginosa risk factors | Present |
→AntibioticsIndicated, recommend use
- Antibiotic indication (Anthonisen)：Cardinal symptoms 3/3: met (all three / two including purulence / ventilation needed)
- Antibiotic regimen：Pseudomonas risk factors: ciprofloxacin, or an anti-pseudomonal β-lactam ± aminoglycoside
- Systemic steroid：Prednisolone 40 mg/d × 5 days (or nebulized budesonide as an alternative)
| Worsening dyspnea | Absent |
|---|---|
| Increased sputum volume | Absent |
| Sputum purulence | Absent |
| Needs invasive or noninvasive ventilation | No |
| Arterial pH (optional) | 7.30 |
| Pseudomonas aeruginosa risk factors | Absent |
→AntibioticsNot recommended for now
- Antibiotic indication (Anthonisen)：Cardinal symptoms 0/3: not met
- Antibiotic regimen：Antibiotics not recommended for now (only 1 symptom, or 2 without purulence and no ventilation need)
- Systemic steroid：Prednisolone 40 mg/d × 5 days (or nebulized budesonide as an alternative)

FAQ
Frequently asked questions
- What are the limits and cautions when using COPD Acute Exacerbation (AECOPD) Management?
- 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 COPD Acute Exacerbation (AECOPD) Management 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 COPD Acute Exacerbation (AECOPD) Management calculated in practice? Can you show a worked example?
