Peak expiratory flow measured with the mini wright peak flow meter in children

Abstract
We established pediatric reference values for peak expiratory flow rate (PEFR), using the Mini Wright Peak Flow Meter. The study was based on 1,566 Mediterranean white children, aged 7 to 14 years from Valencia (Spain) schools. Height was the biometric variable with the greatest correlation to PEFR in both sexes; significant differences were noted between males and females. Prediction equations and percentile tables are presented for each sex. The performance of the Mini Wright Peak Flow Meter was compared with that of a spirometer.
