    INPUT: A nasogastric tube terminates in the stomach . Cardiomediastinal and hilar contours are unchanged . Bilateral , multifocal areas of consolidation appear relatively unchanged . Stable , small left pleural effusion . No pneumothorax . Previously seen free intra-abdominal air is not identified on the current study , but given that this is not a true upright radiograph , pneumoperitoneum can not be excluded . Recommend repeat upright PA and lateral radiographs or CT for definitive evaluation of intra-abdominal free air .
    OUTPUT:
