Background
The pleural cavity is a closed potential lacuna formed by two layers of visceral walls of pleura turning and moving at the lung root, and consists of a visceral layer of pleura closely attached to the surface of the lung and a parietal layer of pleura closely attached to the inner wall of the thorax, wherein the left and the right are not communicated with each other, no gas is in the cavity, only a small amount of serous fluid is in the cavity, the friction during breathing can be reduced, the negative pressure in the cavity is favorable for the expansion of the lung, and the backflow of venous blood and lymph fluid is favorable. With respiratory motion, the negative pressure within the pleural cavity changes, which is a physiological phenomenon. The chest can cause pneumothorax or hemothorax after severe trauma (some people also can have spontaneous pneumothorax), and when a large amount of gas or liquid exists in the pleural cavity, the lung can be compressed to different degrees to influence breathing; in addition, if the pressure in one pleural cavity is too high, the mediastinum (heart, great vessel, trachea, etc.) can be caused to shift. If the patient is not treated in time, the life will be affected in a short time. This is therapeutically necessary for patients with hemothorax or pneumothorax to puncture the thorax to withdraw fluid or gas and then place a closed thoracic drainage device to drain the gas or fluid from the pleural cavity.
