Bilateral chest drains are present. There are lateral fractures of the right sixth, seventh, and eighth ribs with associated subcutaneous emphysema. The right lung is lucent, suggesting a supine pneumothorax, and there is a mild mediastinal shift to the left. There is also left lower lobe atelectasis, which may be related to the positioning of the endotracheal tube.
