The lungs then shrink down and collapse.Įxamples of a trauma or injury that could cause hemopneumothorax include: The lungs aren’t able to expand to let in air. As a result, the functioning of the lungs is disrupted. When the chest wall is injured, blood, air, or both can enter the thin fluid-filled space surrounding the lungs, which is called the pleural space.
Hemopneumothorax is most frequently caused by a trauma or blunt or penetrating injury to the chest.
