🫁 Pneumothorax Management Pathway
This tool gives management decisions for tension, primary spontaneous, and secondary spontaneous pneumothorax per BTS 2023.
Tension pneumothorax is a clinical diagnosis treated before imaging, whereas stable spontaneous pneumothorax is managed by symptoms rather than size alone. (original synthesis · not guideline verbatim)

When to use
Use to act immediately on tension pneumothorax and to choose conservative care, aspiration, or drainage for spontaneous pneumothorax by symptoms and size.
How it works
Tension → immediate needle decompression then chest drain. PSP minimally symptomatic → conservative; symptomatic → aspiration/Heimlich/drain. SSP → < 1 cm conservative, 1–2 cm aspiration, unstable/> 2 cm drain.
Key points
- Tension pneumothorax is a clinical diagnosis treated before imaging, whereas stable spontaneous pneumothorax is managed by symptoms rather than size alone. (original synthesis · not guideline verbatim)
- SSP has poor pulmonary reserve and usually requires drainage and admission.
- Recurrence or persistent air leak prompts VATS with pleurodesis and smoking cessation.

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Type | Tension pneumothorax (hemodynamic compromise/rapid deterioration) |
|---|---|
| Symptoms/size | Minimal symptoms/small |
→PneumothoraxTension pneumothorax — immediate decompression
- Immediate management：Do not wait for imaging! Immediate needle decompression: 14G cannula at the 2nd intercostal space midclavicular line or 4th/5th intercostal space anterior/mid-axillary line; then place a chest drain
- Support：High-concentration oxygen, monitoring; minimize airway pressure in mechanically ventilated patients
- Basis：BTS 2023 / trauma airway-circulation resuscitation
| Type | Secondary spontaneous pneumothorax (SSP, underlying lung disease) |
|---|---|
| Symptoms/size | Symptomatic/dyspnea or larger |
→PneumothoraxSecondary spontaneous pneumothorax (SSP)
- Management (by hilar size)：< 1 cm: admit, conservative + oxygen observation; 1–2 cm: 14–16G needle aspiration + admit, observe; unstable/dyspnea/> 2 cm or > 1 cm after aspiration: < 14F chest drain
- Key points：SSP has poor pulmonary reserve, often needing drainage and admission; treat the underlying lung disease; minimize airway pressure in mechanically ventilated patients
- Recurrence prevention：Persistent air leak/good baseline: assess for surgery (VATS) + pleurodesis; smoking cessation
