Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The endotracheal tube terminates 5 .5 cm above the carina , positioned above the level of the clavicular heads . Nasogastric tube passes into the stomach , tip not well seen due to underpenetration . There is a left subclavian central line , which extends to the upper SVC . Lung volumes are low . There is resultant basal atelectasis and bronchovascular crowding . Heart size is stable . There is a left pleural effusion layering posteriorly and causing diffuse increased opacity of the left hemithorax . There is engorgement of the pulmonary vasculature , with perihilar haziness compatible with pulmonary edema . There is no focal consolidation to suggest pneumonia . There is no pneumothorax .
    OUTPUT:
    
1 . Persistent low lung volumes , vascular congestion and mild pulmonary edema little changed compared to one day prior . 2 . Left pleural effusion , now latering dependently . 3 . Slightly high positioning of the endotracheal tube , which could be slightly advanced for optimal positioning .
