    INPUT: Portable frontal chest radiographs demonstrate an endotracheal tube terminating 3 .4 cm above the level of the carina in appropriate position . A left subclavian line terminates in the low SVC . An enteric tube descends in an uncomplicated course , its terminal end outside the field of view . Mild cardiomegaly is unchanged . Improved pulmonary edema is demonstrated by narrower vascular pedicle and dramatically improved transient pulmonary artery dilatation seen previously . Bibasilar consolidations are apparent , left worse than right , likely atelectasis but infection can not be excluded .
    OUTPUT:
    
Improved pulmonary edema . Bibasilar consolidations , left worse than right , likely atelectasis although infection can not be excluded .
