    INPUT: Endotracheal tube tip terminates approximately 3 .8 cm from the carina . An enteric tube is within the stomach . Heart size is normal . Mediastinal and hilar contours are unremarkable . The pulmonary vasculature is not engorged . Patchy opacities are seen in the lung bases which may reflect areas of atelectasis in the setting of low lung volumes . No focal consolidation , pleural effusion or pneumothorax is present . No acute osseous abnormality is demonstrated .
    OUTPUT:
    
1 . Standard positioning of the endotracheal and enteric tubes . 2 . Low lung volumes with patchy bibasilar airspace opacities , likely atelectasis .
