A Study of Peak Expiratory Flow Rate in Children
Journal Title: INTERNATIONAL JOURNAL OF RECENT TRENDS IN SCIENCE AND TECHNOLOGY - Year 2014, Vol 10, Issue 2
Abstract
Background: A lot of age-specific variations in Peak Expiratory Flow Rate (PEFR) are expected in paediatrics age group compared to adults. Therefore availability of normal values for different age group is absolutely essential for logical interpretation of PEFR. Only few studies are available on ventilator functions for children of South Indians 7–12 years of Age. Method: One hundred and eighty apparently healthy school children (93 Male, 87 Female) from age group 7–12 years were included in the study. PEFR was measured in L/min with computarised spirometer, winspiroPRO. Result: Positive correlation was seen between age, height, weight, Body surface area, and PEFR. The regression equations for PEFR were determined for boys and girls separately. The prediction equation for PEFR based on Weight, height, age and BSA was PEFR for boys = 1.25(height) + 19.86(age) + 1.03(weight) – 164.55; PEFR for girls = 4.56(height) + 1.671(age) + 1.22(weight) – 451.09 In both male and female children, PEFR significantly increases (p<0.001) with height, weight, age, and Body Surface Area (BSA). Conclusion: PEFR is a reliable measurement, which can be used in South Indians for assessment of airway obstruction. Prediction formula is derived for use in this population.
