This prevents the lung from expanding properly.

⭐ What is a Collapsed Lung?

Occurs when air enters the pleural space.

This may happen due to:

  • A penetrating chest injury (sucking chest wound)

👉 This can cause the lung to collapse

  • Apply pressure to the chest
  • Attempt to seal or treat the wound

💡 Key Takeaways
