Subsequent radiographs: Interval intubation with endotracheal tube tip initially overlying the right mainstem bronchus, later retracted to 3 cm above the carina, and finally 5 cm above the carina on the most recent film. Marked increase in airspace opacity in the left lung with volume loss and associated mediastinal shift to the left, followed by re-expansion of the left lung with persistent coarse reticular opacities.
