Peak Exploratory Flow Rate (PEFR) is a simple, economical, reproducible, non-invasive test, which can be
quickly performed with ease. PEFR was assessed in 36 children with adenotonsillar enlargement with mean
age 10.75 years and equal number of age and sex matched normal children who acted as controls. PEFR
was found to be 250. 61 ± 66.92 lt/min in controls and 216.85 ± 59.76 lt/min in children with adenotonsillar
enlargement signifying impairment of PEFR in children in the second group.
