Pneumothorax is a collapsed lung. As a result of disease or injury (stab or gunshot wounds), air can enter the pleural cavity from the lungs or through the chest wall. It is called pneumothorax. It occurs when air leaks into the space between your lung and chest wall. As air builds up, the pressure inside the pleural space increases and causes the lung to collapse. In the old treatment of tuberculosis, the air was purposely injected into the pleural cavity to collapse and rest the lung. This was known as artificial pneumothorax.

Hydropneumothorax: Air in the pleural cavity associated with serous fluid is known as hydropneumothorax.

Pyopneumothorax: Air in the pleural cavity associated with pus is known as pyopneumothorax.

Haemopneumothorax: Air in the pleural cavity associated with blood is known as haemopneumothorax.

The main symptoms of a pneumothorax are sudden chest pain and shortness of breath. Treatment generally involves inserting a flexible tube or needle between the ribs to remove the excess air.

The causes are categorized as either primary spontaneous, secondary spontaneous, or traumatic.

  • A primary spontaneous pneumothorax occurs when the person has no known history of lung disease.
  • Secondary spontaneous pneumothorax can be caused by a variety of lung diseases and disorders.
  • A traumatic pneumothorax is the result of an impact or injury.
