    INPUT: A single AP radiograph of the chest was acquired . The endotracheal tube is low lying , ending 1 .2 cm above the level of the carina . An enteric catheter courses below the level of the diaphragm and out of the field of view inferiorly . Lung volumes are low , causing exaggeration of the heart size and accentuation of the pulmonary vasculature . There is mild - to - moderate left retrocardiac atelectasis and minimal right lower lung atelectasis . Aspiration pneumonitis at the left lung base is not excluded . The lungs are otherwise clear . There are no pleural effusions . No pneumothorax is seen . The heart size is normal . The mediastinal contours are normal allowing for supine technique .
    OUTPUT:
    
1 . Low lung volumes with mild - to - moderate left lower lung atelectasis and minimal right lower lung atelectasis . Left lower lung aspiration pneumonitis in the setting of recent intubation is not excluded . 2 . Low - lying endotracheal tube terminating 1 .3 cm above the level of the carina . Recommend retraction by 2 - 3 cm .
