    INPUT: Rotated positioning . Because of differences in positioning , it is difficult to directly compare the position of the tracheostomy tube on the 2 examinations . The distance between the tip of the tube at the carina measures ___ .3 mm on the current exam , compared with 30 .6 mm on the exam obtained earlier today . The balloon about the tracheostomy tube appears roughly similar in position . Inspiratory volumes are low . Again seen is considerable opacification in the right lung and left lower lobe collapse and consolidation with air bronchograms as well as a right pleural effusion . The possibility of a small left effusion can not be excluded . Indwelling right subclavian central line tip lies near the SVC / RA junction , similar to prior . Left IJ central line tip overlies the mid SVC . There are also similar to prior .
    OUTPUT:
    
ET tube tip lies approximately 1 .5 cm more distal on the current examination . Extensive airspace opacity in the right lung again seen , most pronounced at the base . Left lower lobe consolidation also again seen . Small to moderate layering right effusion . Other lines and tubes as described
