Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Portable frontal chest radiographs demonstrate interval placement of an endotracheal tube , which terminates in the mid to upper thoracic trachea , and an enteric tube which courses below the diaphragm and off the inferior edge of the image . A left chest wall pacer device is unchanged in position . Heart size is likely unchanged . Diffuse pulmonary opacities are increased compared to prior exam . Pleural effusions are incompletely imaged on this exam .
    OUTPUT:
    
1 . Endotracheal tube terminating in the mid to upper thoracic trachea . Enteric tube courses below the diaphragm and off the inferior edge of the image . 2 . Increased pulmonary opacity bilaterally . Given short interval since prior radiograph , this could represent either flash pulmonary edema or sequela of aspiration .
