Lesson Summary. Pneumothorax is a collapsed lung due to gas in the pleural space of the chest. It can be open (air leaking in from outside via puncture) or closed (chest wall intact). The three major types of pneumothorax are: Spontaneous pneumothorax, which occurs suddenly or for no distinguishable reason.
In this type of pneumothorax, air enters the chest cavity, but cannot escape. This greatly increased pressure in the pleural space causes the lung to collapse completely, compresses the heart, and pushes the heart and associated blood vessels toward the unaffected side.
