Definition & History of Definition & History of PneumothoraxPneumothorax
Pneumothorax is defined as air in the pleural Pneumothorax is defined as air in the pleural space that is, between the lung and the chest wall. space that is, between the lung and the chest wall.
Primary pneumothoraxPrimary pneumothorax arise in otherwise healthy arise in otherwise healthy people without any lung disease. people without any lung disease.
Secondary pneumothoraxSecondary pneumothorax arise in subjects with arise in subjects with underlying lung disease. underlying lung disease.
The term pneumothorax was first used by Itard, a The term pneumothorax was first used by Itard, a student of Laennec, in 1803, and Laennec himself student of Laennec, in 1803, and Laennec himself described the pneumothorax in 1819 described the pneumothorax in 1819
