    INPUT: Endotracheal tube terminates 4 .4 cm above the carina . Enteric tube courses below the diaphragm , terminating in the left upper quadrant . There has been interval placement of right internal jugular central venous catheter which terminates in the lower SVC , without evidence of pneumothorax . Cardiac and mediastinal silhouettes are stable . Mild interstitial edema persists . Patchy left base retrocardiac opacity is again seen which may be due to atelectasis although infection or aspiration are not excluded in the appropriate clinical setting . No large pleural effusion is seen although small pleural effusion , particularly on the left , difficult to exclude .
    OUTPUT:
