The procedure is done to drain air from the space if the lung is collapsed (a condition called pneumothorax Pneumothorax A pneumothorax is the presence of air between the two layers of pleura (thin, transparent, two-layered membrane that covers the lungs and also lines the inside of the chest wall), resulting... read more ). It is also sometimes done to drain fluid from the pleural space (called pleural effusion Pleural Effusion Pleural effusion is the abnormal accumulation of fluid in the pleural space (the area between the two layers of the thin membrane that covers the lungs).

In some situations, insertion of a chest tube is an emergency, potentially life-saving procedure.
Chest tube insertion is done with the person awake, although sometimes a sedative is given. The doctor anesthetizes the area between two ribs and then makes a small incision and inserts the tube. The tube is connected to suction. A chest x-ray Chest Imaging is usually done after the tube is inserted to confirm correct placement. Severe complications are infrequent. They can include chest pain, puncture of the lung or diaphragm, accumulation of air under the skin, and infection. If a large amount of fluid that has been present for weeks to months is withdrawn rapidly, fluid can accumulate within the lung itself (pulmonary edema). Occasionally, a tube needs to be replaced because it kinks, becomes dislodged, or becomes blocked by a blood clot.
