What does pneumothorax refer to?

Pneumothorax refers to the presence of air in the pleural space, which is the area between the lungs and the chest wall. This condition can occur as a result of trauma, such as a penetrating injury, or spontaneously, and it can lead to lung collapse. When air enters this space, it creates pressure that can prevent the lung from fully expanding during inhalation, causing difficulty in breathing and potentially leading to serious respiratory issues.

Understanding the nature of a pneumothorax is crucial for proper assessment and treatment in wilderness medicine situations, where immediate care may be required. Identifying the signs and symptoms, such as sudden chest pain and shortness of breath, is essential for recognizing this condition and providing appropriate interventions.
