Document Summary
If the thin, double-layered pleural membrane is disrupted by lung disease, surgery, or trauma, the negative pressure between the pleural layers may be lost. The lung then collapses because it is no longer drawn outward as the diaphragm and intercostal muscles contract during inhalation. When air collects in the pleural space, it is known as a pneumothorax. A haemothorax is the accumulation of blood in the pleural space, and a pleural effusion exists when there is excessive fluid in the pleural space. The air, blood, or fluid in the pleural space places pressure on lung tissue and interferes with lung expansion. Chest tubes may be inserted into the pleural cavity to restore negative pressure and drain collected fluid or blood. Because air rises, chest tubes for pneumothorax often are placed in the upper anterior thorax, whereas chest tubes used to drain blood and fluid generally are placed in the lower lateral chest wall.
