Received: November 07, 2016; Accepted: November 24, 2016 ABSTRACT Background: Peak expiratory flow rate (PEFR) assesses the overall functional status of the respiratory system. Correlation coefficient was also calculated between the height and PEFR, measured with pocket flow meter in all the five groups; 0.64, 0.68, 0.25, 0.47, and 0.69 from Groups I to V. Conclusion: PEFR is increased with the increasing in height of the subjects. Peak Expiratory Flow Rate; School Children; Mini Wright Flow Meter; Pulmonary Functions INTRODUCTION Way back in 1942 Hadorn suggested the use of maximum forced expiratory flow rate, i.e., peak expiratory flow rate (PEFR) as a physiological index for the functional status of the respiratory system as a whole. After thorough explanation about this study, subjects were included after obtaining the written informed consent from their school authorities. 119 school going healthy boys were selected randomly, aged between 5 and 16 years. Exclusion Criteria Smoker's, subjects with H/O recurrent respiratory tract infections, H/O bronchial asthma, H/O congenital respiratory problems, deformities of the spine, recent H/O surgeries, and H/O continuous exposure to the industrial dust (cotton mills, etc.) are all excluded from the study. In general, pulmonary function tests values are more in male subjects than their female counter partners because of the greater strength of the respiratory muscles. More protein buildup means more anabolic processes and more anabolic processes means more oxygen demand and more oxygen demand can be maintained by increased intake of oxygen, which will result in greater PEFR values in males...
