Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube terminates 2 .6 cm above the carina . Particularly as the head is extended , any further movement centrally could result in unilateral intubation . New orogastric tube terminates just beyond the GE junction and could be advanced 7 to 10 cm . Bilateral chest tubes are redemonstrated , without evidence of pneumothorax . Left subclavian central venous catheter appears to be located in the distal subclavian or proximal left brachiocephalic vein . Left sided arterial line terminates in the axilla . The lungs are low in volume with developing opacity in the left upper lobe . Tortuous and unfolded aorta is noted with calcification . The heart is normal in size . Normal cardiomediastinal silhouette .
    OUTPUT:
    
1 . Endotracheal tube 2 .6 cm above the carina should not be advanced any further to avoid unilateral intubation . Orogastric tube could be advanced 7 to 10 cm as tip is just beyond the GE junction . 2 . Left subclavian catheter terminates in the distal subclavian or proximal left brachiocephalic vein and may no longer be central . Left axillary arterial line terminates in the axilla . 3 . New left upper lobe opacity could reflect developing pneumonia or an aspiration event . Preliminary findings were discussed with Dr . ___ by Dr . ___ at ___ on ___ by phone . Additional findings were conveyed to Dr . ___ by Dr . ___ by phone at ___ on ___ .
