Set camera to cine (high frame-rate) mode. In AP and lateral projections, fluoroscope and observe the patient's airway and thorax during inspiration and expiration. Look for abnormal narrowing (croup) or collapse of the airway (tracheomalacia). Check for symmetrical aeration of the lungs during inspiration and expiration. On expiration the trachea buckles to the side opposite the arch.
Views to Take:
In AP and lateral projections, obtain spot films of the airway and chest during inspiration and expiration.
