    INPUT: A newly placed endotracheal tube terminates at the level of the clavicles . A new OG tube coils in the larynx but enters a large hiatal hernia . A right IJ central venous catheter terminates in the low SVC . Lung volumes are low . Left basilar airspace opacities are most likely due to atelectasis adjacent to the hiatal hernia . The followup radiograph performed shortly thereafter shows further advancement of the OG tube into the intrathoracic stomach .
    OUTPUT:
    
OG tube terminates in the intrathoracic stomach . ET tube terminates at the level of the clavicles . Left basilar airspace opacities are most likely atelectasis around the large hiatal hernia .
