COPD Exacerbation - CCS Case Guide

Key Takeaway: Acute COPD exacerbation is characterized by worsening dyspnea, cough, and sputum production beyond normal day-to-day variation. Prompt treatment with bronchodilators, systemic corticosteroids, and antibiotics (when indicated) reduces morbidity.

Acute COPD exacerbation is characterized by worsening dyspnea, cough, and sputum production beyond normal day-to-day variation. Prompt treatment with bronchodilators, systemic corticosteroids, and antibiotics (when indicated) reduces morbidity. Careful oxygen management is critical to avoid CO2 retention.

Recognizing the COPD Exacerbation Presentation

  • History: Worsening dyspnea, increased sputum volume and purulence, increased cough, history of smoking and prior COPD diagnosis
  • Physical Exam: Wheezing, decreased breath sounds, use of accessory muscles, pursed-lip breathing, barrel chest, prolonged expiratory phase
  • Vital Signs: Tachypnea, tachycardia, possible hypoxia (SpO2 < 90%), possible CO2 retention

Immediate Actions (First 5 Minutes)

These orders should be placed immediately — timing is scored:

Critical First Orders

  • ✓ Supplemental oxygen titrated to SpO2 88-92%
  • ✓ Nebulized albuterol and ipratropium
  • ✓ Systemic corticosteroids (prednisone 40 mg or methylprednisolone IV)
  • ✓ ABG if moderate-to-severe distress
  • ✓ Chest X-ray

Complete Workup

After initial stabilization, complete the diagnostic workup:

  • ABG (assess PaCO2, pH, PaO2)
  • Chest X-ray (rule out pneumonia, pneumothorax, effusion)
  • CBC with differential
  • BMP
  • Sputum culture if purulent sputum
  • Procalcitonin (guide antibiotic use)
  • ECG (right heart strain, arrhythmia)
  • BNP if heart failure suspected as co-precipitant

Treatment

Bronchodilators

  • Albuterol nebulizer every 4 hours (or more frequently if severe)
  • Ipratropium nebulizer every 6 hours
  • Consider continuous nebulization if severe

Corticosteroids

  • Prednisone 40 mg PO daily for 5 days
  • Or methylprednisolone 125 mg IV if unable to take PO
  • No taper needed for 5-day course

Antibiotics

  • Indicated if increased sputum purulence plus increased dyspnea or sputum volume
  • Azithromycin 500 mg day 1 then 250 mg days 2-5
  • Or doxycycline 100 mg BID for 5 days
  • Or amoxicillin-clavulanate if more severe

Ventilatory Support

  • BiPAP (NIPPV) for moderate-severe respiratory acidosis (pH < 7.35)
  • Intubation and mechanical ventilation if BiPAP fails or patient obtunded
  • Target SpO2 88-92% to avoid CO2 narcosis

Common Pitfalls

Scoring Tip: These are the most commonly missed actions for COPD Exacerbation cases.

  • Over-oxygenation (targeting SpO2 > 95% may worsen CO2 retention)
  • Not obtaining ABG in moderate-to-severe exacerbation
  • Omitting systemic corticosteroids
  • Using antibiotics without indication (no purulent sputum change)
  • Failing to initiate BiPAP when pH < 7.35 with hypercapnia
  • Not addressing smoking cessation before discharge

Disposition

  • ICU if requiring BiPAP or intubation
  • Telemetry floor for moderate exacerbation
  • Discharge when on room air or baseline O2, symptom improvement, and 24-hour inhaler spacing
  • Pulmonology follow-up and smoking cessation counseling

Key Orders Checklist

  • ☐ Albuterol and ipratropium nebulizers
  • ☐ Prednisone 40 mg PO daily
  • ☐ ABG
  • ☐ Chest X-ray
  • ☐ Oxygen titrated to SpO2 88-92%
  • ☐ BiPAP if respiratory acidosis
