    INPUT: A semi upright portable frontal chest radiograph demonstrates a endotracheal tube terminating in the mid thoracic trachea and an enteric tube which terminates just distal to the GE junction . There are low lung volumes , as before . The heart is likely normal in size , allowing for exaggeration due to low lung volumes . Bilateral pulmonary opacities are increased compared to the most recent chest radiograph . The visualized upper abdomen is unremarkable .
    OUTPUT:
    
1 . Increased bilateral pulmonary opacities , possibly flash pulmonary edema . However , in the right clinical setting , ARDS or multifocal pneumonia can also be a consideration . 2 . Endotracheal tube in appropriate position . Enteric tube terminating just distal to the GE junction . On subsequent chest radiograph , this tube is advanced .
