Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is intubated . The endotracheal tube terminates near the thoracic inlet , approximately 6 cm above the carina . The balloon is not well seen . The lung volumes are low . Allowing for technique , the cardiac , mediastinal , and hilar contours are probably within normal range . The lungs appear clear . The extreme left costophrenic sulcus is partly excluded , but there is no evidence for pleural effusion . There is no pneumothorax .
    OUTPUT:
    
Somewhat high - lying endotracheal tube , about 6 cm above the carina . If clinically indicated , advancing the tube slightly could be considered for more optimal positioning ; the balloon is also not well seen and could accordingly be deflated potentially .
