Final answer:
Hemothorax is the term used when blood gets into the pleural space, which is a common complication of a traumatic pneumothorax.
Step-by-step explanation:
A common complication of a traumatic pneumothorax is when blood gets into the pleural space, which is called hemothorax. Hemothorax occurs when blood collects in the pleural cavity, the space between the lung and the chest wall. This can be caused by injury to blood vessels or organs in the chest, leading to bleeding into the pleural space.
