    INPUT: There is moderately severe pulmonary edema . In comparison to the prior study performed 1 hour earlier , there is increasing opacification of the left hemithorax which may be due to a combination of layering pleural effusion and pulmonary edema . A moderate / large left pleural effusion also appears to be slightly increased . No pneumothorax . Heart size is moderately enlarged . There has been interval placement of a left subclavian line which terminates in the brachiocephalic vein . Endotracheal tube is again noted to terminate approximately 7 .3 cm above the carina . Inferior tip of the enteric tube is not visualized .
    OUTPUT:
