Refractory hypoxemia that does not improve with supplemental oxygen should immediately raise concern for a right-to-left shunt. In this ED and ICU case review, we walk through a patient with acute pulmonary embolism causing severe hypoxemia due to intracardiac shunting, reviewing the underlying physiology, diagnostic approach, and management considerations. We break down: • Mechanisms of refractory hypoxemia • Pulmonary embolism physiology and RV failure • Right-to-left shunt (including PFO physiology) • Why oxygen and ventilation may fail • ED and ICU diagnostic pearls • Management considerations in critically ill patients Link to video: https://www.youtube.com/watch?v=Qey9aRZRGk0 📚 DOWNLOAD PDF FOR THIS VIDEO AT LINK BELOW https://www.patreon.com/c/WhiteBoardMedicine We also have MINI COURSES, STUDY GUIDES, PRACTICE QUESTIONS, AD FREE VIDEOS, EDUCATIONAL DISCUSSIONS in our WBM Emergency Critical Care Disclaimer: This content is for educational purposes only and does not constitute medical advice.
