Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Low lung volumes are noted . Lungs however clear without consolidation , effusion , or edema . The cardiomediastinal silhouette is stable . Left chest wall dual lead pacing device is again noted with leads in stable position . There is lucency below the left hemidiaphragm . While this may be within the gastric bubble , free air is not entirely excluded as the configuration on the lateral view does not help further characterize this finding either .
    OUTPUT:
    
No acute cardiopulmonary process . Lucency below the left hemidiaphragm which may be a gastric bubble , however the possibility of free intraperitoneal air given configuration on the lateral is not excluded . Clinical correlation suggested . Repeat exam including lateral decubitus films could also be considered .
