What is the primary purpose of chest tube insertion?

The primary purpose of chest tube insertion is to evacuate air or fluid from the pleural space. This procedure is essential in managing conditions such as pneumothorax (the presence of air in the pleural cavity) or pleural effusion (accumulation of fluid in the pleural cavity). By placing a chest tube, healthcare providers can effectively remove this unwanted air or fluid, allowing the lungs to re-expand and function properly, which is crucial for the patient's respiratory status.

The need for a chest tube arises when there is a buildup that compromises lung function, resulting in difficulty breathing and potential respiratory distress. By alleviating this pressure, the chest tube facilitates breathing and contributes to overall stability in the patient's condition. Thus, evacuation of air or fluid is a fundamental aspect of thoracic trauma management and is vital for effective treatment.
