Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . There is streaky density at the lung bases consistent with subsegmental atelectasis . There is additional hazy density at the right lung base suggestive of pleural fluid . A small focal area of consolidation at the right base can not be excluded . The heart and mediastinal structures are unchanged . The endotracheal tube and nasogastric tube remain in place .
    OUTPUT:
    
Low lung volumes . Subsegmental atelectasis . Focal opacity at the right lung base likely representing pleural fluid and volume loss . A small focal area of consolidation at the right base can not be excluded , however .
