Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube tip terminates approximately 5 .9 cm from the carina . An orogastric tube tip is within the stomach . Heart size is mildly enlarged . Aortic knob is calcified . Perihilar opacities with vascular indistinctness is compatible with mild to moderate pulmonary edema . Focal opacities in the lung bases may suggest superimposed infection or aspiration . Small left pleural effusion is likely present . No large pneumothorax is identified . A catheter is seen coursing from the left axilla , crossing the midline of the chest , with its tip appearing to project over the right apex of the lung .
    OUTPUT:
    
1 . Catheter seen coursing from the left axillary region , crossing the midline chest , with tip projecting over the right lung apex . Given the non-anatomic course of this catheter , it could be external to the patient , but clinical correlation is advised . 2 . Standard positioning of the endotracheal tube and orogastric tube . 3 . Mild to moderate pulmonary edema and small left pleural effusion . Bibasilar airspace opacities could reflect superimposed aspiration or infection .
