ar·ti·fi·cial pneu·mo·tho·rax(ahr'ti-fish'ăl nū'mō-thōr'aks)
Pneumothorax produced by the injection of air, or a more slowly absorbed gas such as nitrogen, into the pleural space to collapse the lung.
An intentionally and artificially induced pneumothorax, used to facilitate transcutaneous mediastinal biopsy and, infrequently, to treat pulmonary tuberculosis and pneumonia. Pneumothorax allows the diseased lung to rest temporarily. The lung collapses when the air enters the pleural space.
Scattered adhesions may afford only a partial collapse. Effusion may occur in about one third of the cases. Hazards include pain, infection, and respiratory distress.
