    INPUT: An ET tube is present , tip lying approximately 4 .8 cm above the carina . An NG tube is present , tip extending beneath diaphragm , off film . A right - sided chest tube is present . Compared with 1 day earlier , hazy opacity at the right base is unchanged and likely represents a combination of pleural fluid and collapse / consolidation . Patchy opacity at the left base is slightly improved . The cardiomediastinal silhouette is grossly unchanged . No pneumothorax is detected . Known rib fractures are not not well depicted radiographically , may correspond to slight irregularity of the right posterior ninth rib Left glenohumeral joint osteoarthritis again noted , incompletely evaluated .
    OUTPUT:
    
Compared 1 day earlier , slight improvement in patchy consolidation at left base . Otherwise , I doubt significant interval change .
