COPD Exacerbation (AECOPD) — Management Pathway

Step-by-step decision

Choose step by step as prompted; reaching an endpoint gives the management recommendation. You can go back a step or restart anytime.

Full pathway

1. [Decision] Severity & site of care
   Outpatient management or admission? (AECOPD = acute worsening of respiratory symptoms beyond normal variation requiring a change in treatment; >80% can be managed as outpatients. Admission indications: severe features (worsening dyspnea at rest, tachypnea, cyanosis, peripheral edema), acute respiratory failure, new signs, no response to initial treatment, serious comorbidity (heart failure / arrhythmia), inadequate home support.)
   • Outpatient (mild) → Outpatient management
   • Admission / ED → Admission · is NIV needed?
2. [End] Outpatient management
   Increase short-acting bronchodilators (SABA ± ipratropium); oral prednisone 40 mg/day × 5 days; add antibiotics for 5 days when Anthonisen criteria are met (increased dyspnea, increased sputum volume, sputum purulence — ≥2 of the three cardinal symptoms including purulence, or need for mechanical ventilation), e.g. amoxicillin-clavulanate / doxycycline / a macrolide; arrange follow-up and pulmonary rehabilitation.
3. [Decision] Admission · is NIV needed?
   Does it meet non-invasive ventilation (NIV) criteria? (NIV indications (any): respiratory acidosis (pH ≤7.35 and/or PaCO2 ≥45 mmHg), severe dyspnea with increased work of breathing (accessory muscles, paradoxical breathing), persistent hypoxemia despite oxygen.)
   • Meets NIV criteria → Non-invasive ventilation
   • Does not (standard admission) → Standard admission
4. [End] Non-invasive ventilation
   NIV (preferred respiratory support) + bronchodilators (nebulized SABA + ipratropium) + systemic steroid (prednisone 40 mg/day × 5, or IV equivalent) + antibiotics per Anthonisen; controlled oxygen SpO2 88–92% (avoid CO2 retention). NIV failure/contraindication, altered consciousness or hemodynamic instability → intubation and invasive ventilation, transfer to ICU.
5. [End] Standard admission
   Bronchodilators (nebulized SABA ± SAMA) + systemic steroid (prednisone 40 mg × 5 days) + antibiotics per Anthonisen for 5 days; controlled oxygen SpO2 88–92%; find the trigger (infection, PE, heart failure), VTE prophylaxis, monitor blood gases, escalate to NIV/ICU if worsening.
