A 30-year-old woman is involved in an automobile accident. The woman, who was not wearing a seat belt, hits her
chest against the steering wheel. When she is brought by ambulance to the emergency room, she is noted to be
cyanotic. Her blood pressure is within normal limits and her heart rate is fast but regular. Her respirations are
rapid and very shallow. She receives no medications in the ambulance. Chest x-ray demonstrates multiple broken
ribs, but no pleural effusion or obvious lung disease. Which of the following mechanisms would most likely
account for this patient's hypoxemia?
A. Decreased capacity for pulmonary diffusion
B. Decreased surface area of alveolar capillary membranes
C. Hypoventilation of central origin
D. Hypoventilation of peripheral origin
E. Inequalities of ventilation and perfusion
