Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: ET tube present , tip 1 .8 cm above the carina . An NG NG tube is present , tip extending beneath diaphragm , off film . Left central line tip overlies proximal / mid SVC . Lordotic positioning . In addition , inspiratory volumes are low . Allowing for this , the cardiomediastinal silhouette is probably unchanged . Patchy opacity at the left lung base with air bronchograms is similar to the prior study . Hazy opacity in the right lung , likely a combination of pleural fluid and atelectasis is also similar to prior study . The possibility of an underlying pneumonic infiltrate at the right base would be difficult to exclude . Again seen is CHF with probable interstitial edema .
    OUTPUT:
    
Left lower lobe collapse and / or consolidation , right - sided effusion with underlying atelectasis and mild CHF are similar to ___ . Given right base opacity , an underlying right base infiltrate would be difficult to exclude .
