Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An AP upright chest radiograph shows lower position of endotracheal tube on the current study with the tip just over 2 cm above the carina . This is low in location , but at the time of dictation , a followup film has been obtained which shows better positioning . Nasogastric tube is seen with the tip and side hole both off the view of the film . Left - sided IJ central venous catheter tip is at the level of the proximal superior vena cava and the tip may abut the right lateral wall of the SVC . Marked cardiomegaly is again noted . Lung parenchyma remains diffusely hazy without focal consolidation or volume loss .
    OUTPUT:
    
1 . Low positioning of endotracheal tube has already been corrected at the time of dictation . 2 . Unchanged positioning of left central venous catheter may abut right lateral wall of the SVC . 3 . Unchanged cardiomegaly and presumed edema .
