Because a jugular line involves placing a needle in the neck and possibly upper chest area, there is a very small chance that the lung on that side may be punctured and that air may collect between the lung and the chest wall. This complication is known as  pneumothorax'. Some pneumothoraces may not need any treatments and others may require the placement of a tube in the chest wall to drain the excess air to the outside. This is known as a chest tube.
