Home > Chest tube


A chest tube or chest drain is a flexible plastic tube that is inserted through the side of the chest into the pleural space. It is used to remove air ( pneumothorax) or fluid ( pleural effusion) from the space.

The free end of the tube is usually attached to an underwater seal, below the level of the chest. This allows egress of air/fluid from the pleural space, while preventing influx of air.

Alternatively, the tube can be attached to a flutter valve. This allows patients with pneumothorax to remain ambulant.
