Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: In comparison with chest radiograph from a few hours earlier , there is no significant change . Lung volumes remain low . Endotracheal tube terminates approximately 3 .6 cm above the carina , unchanged . An enteric feeding tube terminates in the proximal duodenum . Mild - to - moderate pulmonary edema persists . Focal opacities within the right mid lung and left lung base are unchanged and likely reflect atelectasis , though can not exclude infection . No pleural effusion . No pneumothorax . Multiple calcified mediastinal and bilateral hilar lymph nodes suggest prior granulomatous disease . Moderate cardiomegaly is unchanged .
    OUTPUT:
    
1 . Cardiopulmonary support devices are in standard position . Enteric feeding tube terminates in the proximal duodenum . 2 . Focal right mid lung and left basilar opacities likely reflect atelectasis , though infection is also possible . 3 . Mild - to - moderate pulmonary edema is unchanged . 4 . Stable moderate cardiomegaly .
