Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Supine portable view of the chest demonstrates endotracheal tube terminating 7 cm above the carina . Nasogastric tube is positioned in the stomach . Right internal jugular central venous catheter projects over proximal SVC . Swan - Ganz catheter is in unchanged position . Left internal jugular central venous catheter is at the cavoatrial junction . No appreciable pneumothorax . Low lung volumes accentuate bronchovascular markings . Left lung base consolidation persists , likely atelectasis . Trace left pleural effusion is likely . There is no right pleural effusion . Hilar and mediastinal silhouettes are unchanged . Increased opacification of the left hemithorax may reflect mild asymmetric pulmonary edema or pleural fluid .
    OUTPUT:
    
Persistent left lung base consolidation , most likely atelectasis , with associated small left pleural effusion . Asymmetric opacification of the left hemithorax likely represents mild asymmetric pulmonary edema .
