Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Since the prior radiograph performed approximately 30 minutes earlier , the endotracheal tube has been retracted and now terminates approximately 3 .2 cm above the carina . However , the neck is flexed during this study , and the tip of the tube will likely be too low when the head position changes . There is otherwise no significant interval change . Right internal jugular catheter and enteric tube are unchanged . Lung volumes remain low , particularly on the left where there is a moderately - sized pleural effusion . The right lung is essentially clear . No pneumothorax . Heart size is mildly enlarged .
    OUTPUT:
    
1 . Endotracheal tube terminates approximately 3 .2 cm above the carina with the neck in flexion . Please note that the tube will likely be too low with changes in neck positioning . 2 . Otherwise no change from 30 minutes prior .
