    INPUT: There is a suboptimal inspiratory effort , and the low lung volumes . Allowing for changes due to this , there is stable at least moderate global cardiomegaly . The bilateral hila are difficult to assess , but appear within normal limits . There are diffuse , centrally predominant interstitial opacities with suggestion of interlobular septal thickening , consistent with pulmonary vascular congestion and worsening now moderate pulmonary edema . Bibasilar opacities likely reflect relaxation atelectasis . There is no focal lung consolidation otherwise . There is no pneumothorax . There bilateral layering small pleural effusions . effusions
    OUTPUT:
    
1 . Pulmonary vascular congestion and worsening moderate pulmonary edema . 2 . Bilateral small layering pleural effusions . 3 . Low lung volumes . Stable at least moderate global cardiomegaly .
