    INPUT: A right IJ central line terminates in the right atrium . This could be pulled back 2 - 3 cm to be at the superior cavoatrial junction . The lungs are hyperinflated and demonstrate emphysematous changes . A new opacity in the right lung base likely reflects atelectasis , but can not exclude pneumonia or aspiration in the right clinical setting . There is possible small right pleural effusion . There is no pleural effusion . The cardiomediastinal silhouette is unremarkable .
    OUTPUT:
