In this prospective study, chest radiographs were obtained in 23 children during 33 acute asthmatic episodes. The degree of hyperinflation was assessed radiologically by three methods and compared to the clinical findings. There was no correlation between the radiologic impression of hyperinflation and the clinical severity of the asthmatic episode.
