Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The endotracheal tube is in appropriate position approximately 4 cm above the carina . A nasogastric tube passes inferiorly into the stomach out of view , with the side port overlying the expected location of the stomach . A right subclavian central venous catheter terminates at the estimated location of the superior cavoatrial junction . The lung volumes are lower . Chronic collapse of the left lower lobe is again noted due to overlying moderate pleural effusion and compressive atelectasis . There is new heterogeneous opacification of the right lower lobe . The lungs are otherwise clear . There is no pneumothorax . The pulmonary vascular markings are normal .
    OUTPUT:
    
1 . New right lower lobe pneumonia . 2 . Chronic left lower lobe collapse due to left pleural effusion and probable compressive atelectasis . 3 . Endotracheal tube in appropriate and unchanged position .
