Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A portable frontal chest radiograph demonstrates an endotracheal tube with the tip terminating in the mid thoracic trachea . A left chest wall pacing device is unchanged in position , with the leads terminating over the right atrium and ventricle . An enteric tube courses below the diaphragm and off the inferior edge of the image . Lung volumes are low , resulting in increased prominence of the cardiac silhouette and bronchovascular crowding . Even allowing for this , increased opacity bilaterally is consistent with moderate pulmonary edema , although a superimposed infectious process can not be excluded . No pleural effusion or pneumothorax is identified . The visualized upper abdomen is unremarkable . Right posterior ribs , bilateral clavicular and proximal right humerus fractures are chronic .
    OUTPUT:
    
1 . Endotracheal tube terminating in the mid thoracic trachea . 2 . Bilateral opacities likely represent moderate pulmonary edema , although a superimposed infectious process can not be excluded .
