A traumatic pneumothorax is a collection of air inside the chest, between the lung and inner chest wall, which causes the lung to collapse.
See also: Pneumothorax
Traumatic pneumothorax occurs when a physical injury causes the lung to collapse. It can becaused bychest injury from a gunshot or knife wounds. It may also be caused by automobile accidents, or can happen after certain medical procedures.
Hemothorax, a collection of blood between the lung and chest wall, often happens with traumatic pneumothorax.

Exams and Tests
Listening to the chest with a stethoscope may reveal decreased breath sounds on one side of the chest. There may be a bluish coloration of the skin caused by lack of oxygen. The affected person may have a rapid heart rate.
- Arterial blood gas (will reveal low oxygen level in blood)
- Chest x-ray
- Pulse oximetry
The goal of treatment is to remove the air from the pleural space, allowing the lung to re-expand. Small pneumothoraces mayget betteron their own.
Aspiration of air through a catheter to a vacuum bottle may re-expand the lung.
When aspiration is not successful or the pneumothorax is large, the placement of a chest tube between the ribs into the pleural spaceallows the air to be removed from the pleural space. Re-expansion of the lung may take several days with the chest tube left in place.
Hospitalization is required for chest tube management. Antibiotics may be given while the chest tube is in place.
Surgery may be needed to repair tears in the lungs or air passages.
How well a patient doesdepends on how serious the injuries are. However, there are usually no long-term effects after successful treatment for a pneumothorax.
- If untreated, tension pneumothorax can develop.
- There is a small risk of infection from placement of a chest tube.
