Question 6

Whats the difference between spontaneous, simple pneumothorax, and tension?

Answer 6

1. spontaneous: people born with or develop weak areas on surface of the lungs. Occasionally weak areas will rupture allowing air to leak into the pleaural space.
   - expected in patients with sudden chest pain and shortness of breath without known cause
2. 2. simple: result of blunt trauma resulting fractured ribs.
      - hard to diagnose as lung must collapse significantly for decreased breath sounds to be heard.
3. occurs when there is significant air in the pleural space which causes complete collapse of affected lung, and pushes mediastinum itno oppsoit pleural cavity.
   - common in blunt trauma where rib fractures lung or bronchus
