Pneumothorax results from accumulation of gas or air in the pleural space as a result of an interruption in pleural integrity,creating compression of lung tissue.In a closed pneumothorax,there is no communication between the pleura and the external environment,such as may occur from blunt trauma to the chest;this situation is reversed in an open pneumothorax.In a spontaneous pneumothorax,there is no obvious underlying cause of lung collapse.When air enters the pleural space on inspiration but is unable to exit on expiration,a tension pneumothorax exists;this condition is life-threatening.Blood within the pleural space is known as hemothorax,and if air accompanies the blood,it is called hemopneumothorax;this condition may occur with trauma or surgery.
