1 Answer

Stepwise Management of Acute COPD Exacerbation in ED: IMEDIATE (First 30 minutes): 1. Controlled O2 Therapy: - Target SpO2: 88-92% (NOT higher, risk of hypercapnic drive suppression) - Use 24-28% Venturi mask or 1-2 L/min via nasal cannula - ABG urgently to assess pH, pCO2, pO2 2. Short-acting Bronchodilators: - Salbutamol 2.5 mg nebulized q20-30 min x3, then hourly - Ipratropium 0.5 mg nebulized q4-6 h (add for moderate-severe) 3. Systemic Corticosteroids: - Prednisolone 30-40 mg oral for 5 days (preferred - REDUCE trial) - Or IV hydrocortisone 200 mg if unable to take oral 4. Antibiotics (if indicated): - Criteria: increased sputum purulence + increased dyspnea + increased volume - 2 or 3 of above = antibiotic benefit - Amoxicillin/co-amoxiclav OR doxycycline for 5-7 days 5. NIV (BiPAP): if pH <7.35 + pCO2 >45 mmHg after medical therapy - IPAP 12-20 cmH2O, EPAP 4-8 cmH2O - Reassess in 1 hour 6. Intubation: if NIV fails or contraindicated (unconscious, vomiting) For your patient: SpO2 84% = start controlled O2, nebulize bronchodilators, IV steroids, check ABG, arrange for possible NIV if acidotic.
