An enteric tube descends the thorax along the expected course of the esophagus , termination in the stomach in unchanged position when compared to prior radiograph . There has been interval placement of a right sided central line whose tip appears to terminate at the level of the cavoatrial junction . There is no evidence of pneumothorax . The heart appears stably enlarged . The left hemithorax appears better aerated . There is no large pleural effusion . No focal opacity is identified concerning for pneumonia . Persistent mild vascular congestion is present without overt edema . A partially visualized aortic graft is noted .
    OUTPUT:
    
1 . Improved position of the endotracheal tube , now 4 cm above the level of the carina . 2 . Interval placement of right sided central line , its tip terminating at the level of the cavoatrial junction . No pneumothorax is identified on this supine portable radiograph . 3 . Unchanged enteric tube with sideport close to the gastroesophageal junction . Recommend advancing 2 to 3 cm for better placement within the gastric lumen .
