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.
The main symptoms of a pneumothorax are sudden chest pain and shortness of breath. But these symptoms can be caused by a variety of health problems, and some can be life-threatening. If your chest pain is severe or breathing becomes increasingly difficult, get immediate emergency care. A pneumothorax can be caused by: 1  Chest injury. Any blunt or penetrating injury to your chest can cause lung collapse. 2  Lung disease. Damaged lung tissue is more likely to collapse. 3  Ruptured air blisters. Small air blisters (blebs) can develop on the top of your lung.  Mechanical ventilation.
