    INPUT: Endotracheal tube in appropriate position ending approximately 4 .3 cm above the carina . Relative enlargement of the cardiomediastinal silhouette , likely accentuated related to low lung volume . Diffuse increased lung opacity left greater than right lungs , may be related to low volumes however there may be a component of fluid overload . There is no pleural effusion or pneumothorax . Visualized osseous structures are gross unremarkable .
    OUTPUT:
