Why if there is suspicion for aspiration, send for expiratory film (chest x-ray)?

If you: are referring to foreign body aspiration, an expiratory film may provide additional information, because if the aspirated object has occluded a bronchus, that lung or part of the lung will not "deflate" normally upon expiration. An inspiratory film will mask this potential finding.
