A patient with a prior history of diabetes, and a recent knee injury that has severely limited his ability to walk now presents with acute onset of dyspnea and severe hypoxemia. Upon arrival in the ED, he becomes unresponsive and his blood pressure drops to 70/30. You expect that CT angiography will show:
A. Acute respiratory distress syndrome (ARDS)
B. Pulmonary edema
C. Pulmonary embolism
D. Pneumonia
