CCS Case: COPD Exacerbation

Case: COPD Exacerbation

Clinical Setup

• Presentation: 68-year-old male smoker (50 pack-years) with known COPD, 3 days of increased dyspnea, productive cough with purulent sputum, wheezing, SpO2 86% on room air, accessory muscle use.
• Location: Emergency Department.

Optimal Order Pathway

1. Immediate Orders (Minute 0–1):
   • Pulse oximetry, continuous cardiac monitoring, BP q15min.
   • IV access, Normal saline 0.9% IV @ 75–100 mL/hr.
   • Controlled oxygen: nasal cannula titrated to SpO2 88–92% (avoid over-oxygenation in CO2 retainers).
2. Focused Exam (Minute 1–2):
   • Lung exam (wheezes, prolonged expiration, diminished breath sounds), signs of right heart strain (JVD, edema).
3. Diagnostics (Minute 2–5):
   • ABG stat (hypoxia, hypercapnia, acidosis).
   • CBC, BMP, ECG (rule out ischemia/arrhythmia).
   • CXR portable (rule out pneumonia, pneumothorax).
4. Therapeutics (Minute 5–15):
   • Albuterol + Ipratropium nebulizers (scheduled, e.g., q4h).
   • Systemic corticosteroids: Prednisone 40 mg PO daily x5 days (or IV methylprednisolone if unable to take PO).
   • Antibiotics if purulent sputum or ventilatory support needed: e.g., Azithromycin or Doxycycline per local protocol.
   • If severe acidosis/hypercapnia (pH < 7.35, PaCO2 rising): BiPAP noninvasive ventilation.
   • Advance clock in 15–30 min increments; recheck ABG, mental status, work of breathing.
5. Disposition (Minute 15–20):
   • Admit to floor or stepdown/ICU depending on BiPAP need and response.
   • Continue home long-acting bronchodilators; start smoking cessation counseling.
6. Final 2 Minutes:
   • Counsel on inhaler technique, pulmonary rehab referral, influenza/pneumococcal/RSV vaccination.
   • Schedule pulmonology and primary care follow-up; arrange home oxygen evaluation if still hypoxic.
