Your health care provider may note decreased or absent breath sounds on the affected side. Signs or findings of hemothorax may be seen on the following tests:
The goal of treatment is to get the person stable, stop the bleeding, and remove the blood and air in the pleural space.
If a chest tube alone does not control the bleeding, surgery (thoracotomy) may be needed to stop the bleeding.
The cause of the hemothorax will be also treated. The underlying lung may have collapsed. This can lead to breathing difficulty. In people who have had an injury, chest tube drainage may be all that is needed. Surgery may not be necessary.
