Episode notes
Patient-Centred BTS Guideline
- The new BTS guideline shifts focus from pneumothorax size to clinical state, risk features and patient priorities.
- This creates a more nuanced, evidence-based approach to management at the bedside.
Oxygen Speeds Reabsorption Modestly
- High-flow oxygen can increase pneumothorax reabsorption roughly two-to-fourfold by lowering alveolar nitrogen partial pressure.
- The absolute speed gain is modest, so oxygen is used for physiology not rapid radiological clearance.
Primary Versus Secondary Classification Matters
- Primary PSPs occur in younger patients without known lung disease; secondaries have underlying disease or are ≥50 with smoking history.
- The classification matters because older smokers may respond differently to aspiration and other interventions.
