    INPUT: A portable semi-upright AP chest radiograph excludes the lung apices . All lobes remain aerated , with some left retrocardiac consolidation persisting . The tip of the intra-aortic balloon pump projects slightly higher than seen on the study from an hour and a half earlier , now approximately 4 .5 cm below the aortic arch . Swan - Ganz catheter tip extending from right internal jugular vein is directed towards the right main pulmonary outflow tract . The tip of the nasogastric tube is only just below the gastroesophageal junction and could be advanced . Chest tubes appear in unchanged position . The tip of what appears to be an endotracheal tube is just included in the view of the film and also appears unchanged compared to the earlier study .
    OUTPUT:
    
Tip of intra-aortic balloon pump position slightly higher than study from 1 .5 hours earlier , now approximately 4 .5 cm below the aortic arch .
