Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single supine view of the chest provided . The ET tube terminates 4 .0 cm above the carina . Lung volumes are low . There is a probable large left pleural effusion and underlying atelectasis , potential and consolidation . No evidence of pneumothorax . Increased opacity at the right perihilar region and lung base , possibly due to low lung volumes .
    OUTPUT:
    
1 . ET tube terminates 4 .0 cm above the carina . 2 . Opacification of the left hemithorax likely represents a layering pleural effusion and underlying atelectasis / consolidation . 3 . Increased opacity at the right perihilar region and lung base , possibly due to low lung volumes , however attention on followup imaging is recommended .
