What is the purpose of a chest tube?

The purpose of a chest tube is to remove air or fluid from the pleural space, which is essential for restoring normal lung function and ensuring adequate breathing. When air or fluid accumulates in the pleural cavity, it can lead to conditions such as pneumothorax or pleural effusion. A chest tube works by creating a pathway for the trapped air or fluid to exit the pleural space, allowing the lungs to expand properly and facilitating better gas exchange.

By achieving this, the chest tube helps in relieving pressure on the lungs, which can be critical in emergency situations or post-surgical recovery. The successful evacuation of air or fluid not only restores lung function but also enhances oxygenation and overall respiratory efficiency, making it a vital procedure in medical management for patients with these conditions.

Respiratory support and medication administration through inhalation do not relate to the primary function of chest tubes, and monitoring cardiac function is outside the scope of what a chest tube is designed to do.
