Detailed explanation-1: -Thoracentesis is a procedure that is performed to remove fluid or air from the thoracic cavity for both diagnostic and/or therapeutic purposes. [1][2] Thoracentesis is also known as thoracocentesis, pleural tap, needle thoracostomy, or needle decompression.

Detailed explanation-2: -Thoracentesis is a procedure to remove fluid or air from around the lungs. A needle is put through the chest wall into the pleural space. The pleural space is the thin gap between the pleura of the lung and of the inner chest wall. The pleura is a double layer of membranes that surrounds the lungs.

Detailed explanation-3: -The pleural rub sound results from the movement of inflamed and roughened pleural surfaces against one another during movement of the chest wall. [1] This sound is non-musical and described as “grating, ‘’ “creaky, ‘’ or “the sound made by walking on fresh snow.”[2] It is often heard in the upper lung fields.
