Infant with respiratory distress after begin re-intubated

CXR of endotracheal tube in the right mainstem bronchus and after it is pulled back
CXR AP (above) shows an endotracheal tube with its tip projecting deep within the right mainstem bronchus. There is complete atelectasis of the left lung with no mediastinal shift. CXR AP (below) was obtained after the endotracheal tube tip had been pulled back to an appropriate position just above the carina with subsequent near-complete re-expansion of the left lung.

The diagnosis was an endotracheal tube positioned too deep in the right mainstem bronchus.
