The patient’s findings are consistent with a ruptured diaphragm, which is a tear in the muscle that separates the chest and abdominal cavities. A blunt chest trauma can cause a sudden increase in intra-abdominal pressure, which can rupture the diaphragm and allow abdominal organs to herniate into the thorax. This can cause dyspnea, hypotension, shoulder pain, and bowel sounds over the lower thorax. A ruptured abdominal viscus would cause peritonitis, which would present with abdominal pain, distension, fever, and signs of sepsis. A flail chest would cause paradoxical chest movement, respiratory distress, and cyanosis. A mediastinal shift would cause tracheal deviation, decreased breath sounds, and jugular venous distension.
