Chapter 103 - Part E: Oxygen Failure: The 5 Mechanisms That Kill Your Patient
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
In this BoardsCast episode, we finish Tobias Chapter 103 — Lungs with the most terrifying clinical moment:
You gave oxygen, you increased ventilation, and the patient is still hypoxemic. Now what?
This episode reframes hypoxemia into what it actually is: Not one disease, a classification problem.
Because all hypoxemia comes from five mechanisms — and each requires a completely different fix. Miss the category, miss the treatment.
You’ll learn:
- The 5 buckets: low FiO₂, hypoventilation, diffusion impairment, V/Q mismatch, shunt
- Why naming the disease doesn’t solve the immediate oxygen crisis
- Hypoventilation: CO₂ rises and crowds out oxygen (pump failure)
- Diffusion impairment: thickened barrier → O₂ fails first because CO₂ diffuses ~20× faster
- V/Q mismatch: the most common cause — oxygen helps by overloading the healthy units
- Shunt: oxygen-resistant because hemoglobin can’t be “overfilled” — you need recruitment/PEEP
- The bedside algorithm: check CO₂ → give O₂ → judge response → classify (don’t guess)
Key takeaway: You don’t lose patients because oxygen failed. You lose them because you treated the wrong failure.
