    INPUT: Single portable frontal chest radiograph demonstrates endotracheal tube in appropriate position 4 cm above the level of the carina , enteric feeding tube coursing midline with tip in stomach and side ports below the level of the diaphragm . Left subclavian CVL tip is at the cavoatrial junction . Hypo inflated lungs with a new linear platelike left lower lobe atelectasis . Interval improvement in appearance of right lower lobe with decreased rightwards mediastinal shift . Improved but persistent right lower lobe heterogeneous opacity is most likely a combination of hyper expansion pulmonary edema and residual atelectasis . No pleural effusion . No pneumothorax . Heart size , mediastinal contour , and hila are otherwise unremarkable . Limited assessment of the upper abdomen is within normal limits .
    OUTPUT:
    
1 . Decrease in right lower lobe collapse with decreased heterogeneous opacity representing a combination of hyper expansion pulmonary edema and residual atelectasis . 2 . New left lower lobe plate - like atelectasis . 3 . Support lines and tubes as described above .
