Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An endotracheal tube is in unchanged position 5 .1 cm from the carina . Since the prior exam , the catheter in the right main stem bronchus has been removed . There is a new valve overlying the right hilum . It s exact positioning is difficult to determine on this single AP view . A right chest tube is in unchanged position . Since prior exam , the right apical pneumothorax is unchanged . There is increased linear consolidation in the right mid lung zone , likely due to increased atelectasis . The opacity at the right base is unchanged . There is likely a tiny right pleural effusion . The left lung is clear without an opacity . A small left pleural effusion is unchanged . There is no left pneumothorax . The cardiomediastinal silhouette is normal .
    OUTPUT:
    
1 . New valve overlies the right hilum . It s exact location is difficult to determine on this single AP radiograph . 2 . Increased atelectasis in the right mid lung zone . 3 . Otherwise , unchanged radiograph , including a small right apical pneumothorax .
