Chest tubes are medical devices used to remove air, fluid, or pus from the space around the lungs, known as the pleural space. They help restore normal breathing and lung function, especially after surgery or injury. The tube is inserted through the chest wall and connected to a drainage system. These tubes are typically made of flexible plastic and come in various sizes. They are often used in cases of pneumothorax (collapsed lung), hemothorax (blood in the pleural space), or infections. Proper placement and monitoring are essential to ensure effective drainage and prevent complications.
