Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP single view of the chest has been obtained with patient in semi-upright position . Analysis is performed in direct comparison with the next preceding similar study obtained four hours earlier during the same day . During the interval , the patient has been extubated . Previously described right - sided internal jugular approach central venous line remains . Again noted is a feeding tube traversing the entire esophagus terminating in the abdomen . The present image covers the line only about 5 inches below the hiatal area . The more distal portion of the line could be followed further on the previous chest examination , still the tip of the Dobbhoff line was never included in the image . Precise location of the line is essential for patient 's management . It is recommended to perform the study under fluoroscopic control . Comparison of the chest examinations does not reveal any new acute infiltrate . However , the pulmonary vascular pattern appears to be crowded , probably related to the high positioned diaphragms .
    OUTPUT:
    
Termination point of Dobbhoff line not identified on this film .
