    INPUT: Assessment is limited due to positioning . The endotracheal tube ends 3 .6 cm above the carina . An NG tube is in place with the tip out of view . Lung volumes are low . There is bilateral hilar engorgement and pulmonary edema . Apparent mediastinal widening may be due to positioning . Patchy opacities in the retrocardiac region in both the right and the left aspects of the heart may represent atelectasis although infiltrative process can not be excluded . There may be a small layering left - sided pleural effusion . No right - sided pleural effusion is seen . There is no pneumothorax .
    OUTPUT:
    
1 . Endotracheal and NG tubes in appropriate position . 2 . Pulmonary edema . 3 . Patchy opacities in both lung bases may represent atelectasis although infiltrative process can not be excluded .
