Abstract
Objective: To obtain the normal reference values of peak expiratory flow rates (PEFRs) among healthy school-going children between 8 and 12 years and thereby construct a nomogram. Materials And Methods: A cross-sectional study was conducted among healthy children attending schools in Ernakulam district over a period of 1 year. PEFR values were recorded using a Mini-Wright peak flow meter, and the best of three readings was documented. Results: Nine hundred and fifty-four students were studied. PEFR increases as the age increases. A similar trend was observed across various heights. Nomograms based on age and height were constructed separately for boys and girls. Conclusion: Established baseline values of PEFR in this study can be useful in diagnosing and following asthmatic children in Ernakulam district.
