    INPUT: A portable semi-erect frontal chest radiograph demonstrates an endotracheal tube which terminates approximately 2 .7 cm above the carina , in the mid to low thoracic trachea . The heart is mildly enlarged . There is mild to moderate pulmonary edema , as well as a possible right pleural effusion with associated atelectasis . It is difficult to evaluate for focal consolidation in the right lower lung , given overlying opacities . Allowing for this , no definite focal consolidation is identified .
    OUTPUT:
    
1 . Endotracheal tube terminating in the mid to low thoracic trachea . 2 . Mild to moderate pulmonary edema . 3 . Small to moderate right pleural effusion .
