The endotracheal tube terminates approximately 3 cm above the carina . The tip of the transesophageal tube projects over the region of the stomach . Since the prior examination , there has been progressive bibasilar opacities , which may represent atelectasis , though infiltrate is not excluded .

    OUTPUT:
    
1 . Endotracheal tube and transesophageal tube are in adequate position . 2 . Progressive basilar opacities may represent atelectasis , though infiltrate is not excluded .
