Q

What is pneumothorax

A

When air collects in the pleural cavity
Can be traumatic - injury to chest wall allow air through tear in parietal pleura
Spontaneous - ruptured lung

Vacuum lost and cause lungs to collapse

17
Q

Right and left main bronchus

Right is wider shorter and more vertical will pull foreign body to the inferior lobe
