COPD Acute Exacerbation (AECOPD) Management — free guideline decision tool
This tool applies the Anthonisen cardinal symptoms and ventilation needs to judge the antibiotic indication in AECOPD and frames steroid, bronchodilator, oxygen, and ventilation therapy.
Open guideline tool →Guideline-based
Implements the decision logic from published clinical guidelines.

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 8 mg/d 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 8 mg/d as an alternative)
Common questions
What is COPD Acute Exacerbation (AECOPD) Management?
This tool applies the Anthonisen cardinal symptoms and ventilation needs to judge the antibiotic indication in AECOPD and frames steroid, bronchodilator, oxygen, and ventilation therapy.
How is COPD Acute Exacerbation (AECOPD) Management calculated? What is the core formula?
Antibiotics if all three cardinal symptoms, two including purulence, or ventilation needed. Prednisolone 40 mg/d × 5 days; SABA ± SAMA; oxygen SpO₂ 88–92%; NIV at pH < 7.35 or severe dyspnea.
When is COPD Acute Exacerbation (AECOPD) Management used?
Use to decide whether antibiotics are indicated and to set the steroid course, controlled-oxygen target, and noninvasive ventilation threshold.
What are the key clinical points for COPD Acute Exacerbation (AECOPD) Management?
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 88–92% to avoid CO₂ retention in chronic hypercapnia. Pseudomonas risk factors shift empiric therapy to an anti-pseudomonal regimen with cultures.
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.
How is COPD Acute Exacerbation (AECOPD) Management calculated in practice? Can you show a worked example?
