Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heavy pleural thickening and calcifications overlying both sides of the chest make it difficult to assess the lungs . There has been no change in the widespread interstitial abnormality , present on the earliest post trauma imaging studies from ___ , suggesting the these may be chronic findings . The endotracheal tube terminates 6 .8 cm above the carina , with pooling secretions above the ET tube cuff . The NG tube passes into the stomach and out of view . No change in the right pacemaker defibrillator , with leads in the right atrium and right ventricle . Again , the Swan - Ganz catheter passes as far as the descending right pulmonary artery and is obscured by the pacemaker . No pneumothorax .
    OUTPUT:
    
1 . Unchanged widespread interstitial abnormality , present on the earliest post trauma imaging studies from ___ may be chronic interstitial lung disease , rather than pulmonary edema . However , if uncertain of hemodynamic status , Chest CT might be able to distinguish between them . 2 . Endotracheal tube terminates 6 .8 cm above the carina and should be advanced at least 1 cm ; pooling secretions above the ET tube cuff .
