For treatment of a pneumothorax the tube tip is aimed towards the upper pleural cavity and for treatment of a pleural effusion towards the lower part of the pleural cavity
A pleural effusion or a pneumothorax can be treated by positioning a tube into the pleural cavity. Chest drains are usually inserted through the chest wall in the mid-axillary line.
The superior/inferior and medial/lateral positioning of the tube can be determined on a chest X-ray.
Chest drain - treatment for pneumothorax
To drain a pneumothorax the tube is aimed superiorly towards the apex of the pleural cavity.
