    INPUT: The endotracheal tube is slightly high - riding , terminating in the thoracic inlet . Advancement by about 2 cm is suggested for more optimal ventilation . A right subclavian central venous catheter terminates at the superior cavoatrial junction . A nasogastric tube terminates in the stomach . There is no pneumothorax . New left perihilar airspace and interstitial opacities may be due to asymmetric pulmonary edema , aspiration or infection in the appropriate clinical setting . Increased obscuration of the medial left hemidiaphragm may also be due to atelectasis , aspiration or infection .
    OUTPUT:
    
New left perihilar airspace and interstitial opacities may be due to asymmetric pulmonary edema , aspiration or infection in the appropriate clinical context . Slightly high - riding ET tube may be advanced by 2 cm for more optimal ventilation .
