Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An ET tube is present , tip in satisfactory position 4 .5 cm above the carina . Right IJ central line tip overlies the SVC / RA junction . No definite NG tube is identified . However , an NG tube may be faintly seen extending beyond the inferior edge of this film . An additional line or catheter overlies the upper abdomen in the midline , coursing from the right inferior to left superior to overlie the expected site of the gastric fundus . Thin wiring over the chest is also present --? residual lead . Again seen is moderately severe cardiomegaly , with prominence of the mediastinum . There is diffuse vascular blurring , consistent with CHF . There is increased retrocardiac density , consistent with left lower lobe collapse and / or consolidation , and patchy opacity at the right base similar to the prior film . The possibility of trace right pleural fluid can not be excluded .
    OUTPUT:
    
1 . Worsening hazy density suggests increased CHF . Otherwise , cardiomediastinal and pulmonary parenchymal findings are similar to the film from 1 day earlier . 2 . Difficult to distinguish an NG tube . Also , additional line seen over upper abdomen . Please see comment above .
