Collapsed and normal lung

A pneumothorax (a term for collapsed lung) occurs when air leaks into the space between your lungs and chest wall, creating pressure against the lung. Depending on the cause of the pneumothorax, your lung may only partially collapse, or it may collapse completely.

A pneumothorax can be caused by a chest injury, certain medical procedures involving your lung, lung disease, or it may occur for no obvious reason.

A small, uncomplicated pneumothorax may quickly heal on its own, but when the pneumothorax is larger, the excess air is usually removed by inserting a tube or needle between your ribs and slowly removing the air over a few days.
