    INPUT: Portable semi-upright frontal chest radiograph demonstrates an endotracheal tube tip located at least 2 .3 cm from the level of the carina . A left subclavian central venous catheter tip is at the confluence of the SVC and brachiocephalic vein , with its tip projecting laterally against the wall of the SVC . An NG tube is in place , superimposed on the stomach , though the tip is not seen off the inferior margin of the film . Low lung volumes are slightly decreased with bibasilar opacities and bilateral pleural effusions , right greater than left . Mild edema is unchanged . Calcified mitral valve annulus is again noted .
    OUTPUT:
    
1 . Unchanged mild edema , bibasilar atelectasis and bilateral pleural effusion . 2 . Left subclavian central venous catheter tip projects against the wall of the SVC , and repositioning is suggested to prevent erosion of the catheter tip through the wall .
