Ms. Jonus, an 82-year-old female presents to the Emergency Department (ED) after being involved in a motor vehicle collision (MVC). Ms. Jonus was stopped at a stop sign when she was rear-ended by a vehicle at a high speed. The MVC occurred across the street from the hospital, and the elderly woman was able to extricate herself from the vehicle and stumble into the ED with the assistance of the paramedic. She appears pale, diaphoretic, and disoriented. She has an abnormal breathing pattern, which is rapid and shallow, and her level of consciousness is decreased. The paramedic reports that the car was totaled, the windshield and driver's side windows were smashed, and the driver's side seat belt had been torn off, and the steering wheel has been pushed into the dashboard. The paramedic suspects the patient might have sustained significant internal injuries due to the force of the collision. Exhibits Based on the patient's presentation and the information provided, what is the most likely cause of her abnormal breathing pattern?
