COPD Exacerbation Explained: Oxygen, Bronchodilators, Steroids & Ventilation Acute exacerbations of COPD are among the most common causes of emergency department visits, hospital admissions, respiratory failure, and ICU admissions. Understanding the pathophysiology of COPD exacerbations and the principles of respiratory support is essential for clinicians caring for critically ill patients. In this episode, we review the evaluation and management of acute COPD exacerbations, including oxygen therapy, bronchodilator treatment, corticosteroids, antibiotics, noninvasive ventilation, and mechanical ventilation. We also discuss oxygen-induced hypercapnia, the Haldane effect, dynamic hyperinflation, auto-PEEP, and practical considerations when caring for patients with severe airflow obstruction. Topics Covered: • COPD exacerbation pathophysiology • Common causes and triggers • Oxygen therapy and oxygen saturation targets • Oxygen-induced hypercapnia • The Haldane effect • Bronchodilator therapy • Corticosteroids • Antibiotics in COPD exacerbations • Hypercapnic respiratory failure • Noninvasive ventilation (BPAP) • AVAPS • Indications for intubation • Mechanical ventilation in COPD • Dynamic hyperinflation • Auto-PEEP • Clinical pearls and pitfalls 📺 Watch the full video: https://www.youtube.com/watch?v=k0X06HBEnPc 📚 Download the full study guide + access our complete emergency critical care curriculum: https://www.patreon.com/c/WhiteBoardMedicine Our Patreon includes: • 📄 Study guides for every video • 📋 One Pagers • 🎓 Mini-courses (ventilation, shock, RRT & more) • ❓ Practice questions • 🚫 Ad-free videos • 🧠 A structured ICU curriculum 🌐 WhiteBoard Medicine Website: https://whiteboardmedicine.com Disclaimer: This content is intended for educational purposes only and should not be considered medical advice.
