    INPUT: Endotracheal tube terminates 4 .2 cm cranial to the carina in standard position . An upper enteric tube terminates in the mid-to - distal gastric body . Lung volumes are extremely low , exaggerating the cardiac silhouette and pulmonary vasculature though compared to the earlier examination there appears to be mild volume overload . Heart size is likely normal . Lungs are clear taking into account low lung volumes . Pleural surfaces are clear without effusion or pneumothorax .
    OUTPUT:
    
Mild volume overload in the background of low lung volumes . Endotracheal tube and upper enteric tube in standard position .
