Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A portable frontal chest radiograph demonstrates a normal cardiomediastinal silhouette and well - aerated lungs which are clear . There is no focal consolidation , pleural effusion , or pneumothorax . There is no obvious intraperitoneal free air , although this does not appear to be an entirely upright radiograph , which limits evaluation . Gaseous distention of bowel is noted in the visualized upper abdomen . Lucency in the subcutaneous soft tissues is likely subcutaneous emphysema related to recent surgery .
    OUTPUT:
    
1 . This does not appear to be in entirely upright radiograph , which limits evaluation of intraperitoneal free air . Within these limitations , there is no obvious large amount of intraperitoneal free air . If clinically indicated , a repeat radiograph in a true upright position or left lateral decubitus view can be obtained . 2 . Subcutaneous emphysema in the abdominal and lower chest walls is likely related to recent surgery .
