What does pneumothorax indicate?

Pneumothorax specifically refers to the presence of air in the pleural space, which is the thin fluid-filled cavity between the lung and the chest wall. This condition can occur due to various reasons, such as trauma, spontaneous rupture of air blisters on the lung, or as a complication of medical procedures. When air enters this space, it can lead to a collapse of the lung on the affected side, resulting in respiratory distress and decreased oxygenation.

Understanding this definition is crucial for EMTs, as recognizing the signs and symptoms of pneumothorax can help in promptly assessing and managing respiratory emergencies. It is essential to differentiate this condition from others, such as fluid accumulation or infection in the pleural space, as these scenarios require different treatment approaches.
