ABSTRACT
This study was conducted to evaluate whether forced expiratory volume in 1 second FEV[1] for the diagnosis of bronchial reactivity by means of the free-running exercise test and bronchodilator inhalation, could be appropriately replaced by simple measurements of peak expiratory flow rate [PEFR] in children. We studied 108 referred symptomatic children [due to chronic cough or wheezing] suspected to have asthma aged 5-14y. Forced breathing spirometry and the [Mini-Wright peak flow meter] tests were recorded before and fifteen minutes after the challenge with free- running exercise or bronchodilator [Salbutamol] inhalation, regarding the baseline FEV[1] value [FEV[1]> 80% considered as normal]. There was a high correlation between PEFR and FEV[1] [in absolute value and percent predicted] measured before and after bronchodilator inhalation test [r = 0.48, P = 0.05] in comparison to the values referred to free- running exercise test [r = 0.26, P = 0.01]. [forced breathing spirometry] and [Mini-Wright peak flow] cannot be used interchangeably for diagnosing asthma, and PEFR measurement should remain a procedure for monitoring and following up the patients
