    INPUT: The ET tube terminates approximately 2 .9 cm from the carina . There is an OG tube which traverses below the diaphragm with the tip out of view from this radiograph . The Swan - Ganz catheter appears to be in appropriate position . Again seen is moderate enlargement of the heart , overall stable compared to the prior exam . There appears to be slight interval increase in focal consolidation at the left lung base compared to the prior exam . The left upper and mid lung zones appear to be overall well aerated , unchanged compared to the prior exam . There has been slight interval improvement in the right lung field which is obscured by a moderate - to - large right pleural effusion . No evidence of pneumothorax .
    OUTPUT:
    
Slight interval increase in focal consolidation at the left lung base compared to the prior exam , likely secondary to worsening small left pleural effusion . No evidence of pneumothorax .
