A Pleuroscopy is a medical examination that allows your doctor to visualise the space between your lung and the chest wall, called the pleural cavity. The pleural cavity facilitates the optimal performance of the lungs during breathing. An instrument called a Pleuroscope, which consists of a thin tube attached to a camera, is inserted through the chest wall. The procedure does not usually require general anaesthesia. It is done using conscious sedation (medication that makes you sleepy and relaxed). Sometimes an ultrasound may be used to determine the most suitable point for the Pleuroscope entry.
