Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A single portable AP semi-erect view of the chest was obtained . Endotracheal tube terminates approximately 2 cm above the carina . NG tube is within the stomach . Lung volumes are low . Band - like opacity at the left base likely represents atelectasis . There is no focal consolidation , large effusion , or pneumothorax . Enlargement of the cardiac silhouette is likely accentuated by the portable technique , patient positioning , and low lung volumes . Mediastinal contours are unremarkable .
    OUTPUT:
    
1 . Endotracheal tube terminates 2 cm above the carina , consider pulling back by 1 - 2 cm for optimal positioning . 2 . Low lung volumes and basilar atelectasis .
