What condition results from a collapsed lung?

A pneumothorax occurs when air enters the pleural space, leading to a collapsed lung. This condition can result from trauma, such as a rib fracture, or can occur spontaneously. When air accumulates in the pleural space, it increases pressure on the lung, preventing it from fully expanding during inhalation. This can cause difficulty breathing, chest pain, and reduced oxygen levels in the blood.

Understanding the nature of a pneumothorax is essential for EMTs, as timely recognition and management can significantly affect patient outcomes. Treatment may include procedures such as needle decompression or the placement of a chest tube to remove the air and allow the lung to re-expand.
