Abstract
Background: Pulmonary function tests (PFT’s) using complete spirometry help us quantify the state of the respiratory system and aid in the management of respiratory tract illnesses in pediatric practice. However, instrumentation is relatively expensive and only available in hospitals. In contrast, peak expiratory flow rate (PEFR) can be measured using relatively inexpensive peak flow meters and are of value in identifying and assessing the degree of airflow limitation of individuals. To detect any abnormality it is necessary to know the normal values of PEFR in particular region as PEFR depends on geographical, climatic, anthropometric, nutritional, and socioeconomic conditions. The purpose of this study is to get values of PEFR in school going children in Patiala region and its correlation if any with anthropometric parameter such as height.Subjects and Methods:A total 600 children of age group 10- 14 years from schools of Patiala district were taken and age, height,weight of children were noted and PEFR was measured.Results:The correlation of height and weight with PEFR value among rural and urban children was found to be highly significant (p value<0.001). However there was no correlation found between the PEFR values and the age.Conclusion: The correlation of height and weight with PEFR values among urban and rural children was found to be highly significant.
Highlights
Pulmonary function tests (PFTs) are the diagnostic tests that aid in diagnosing and monitoring patients suffering from respiratory diseases
There was no correlation found between the peak expiratory flow rate (PEFR) values and the age. [Table 3] shows correlation of the PEFR values with the anthropometric parameters among urban children
There was no correlation found between the PEFR values and the age .In a study by Kaur Harpreet et al,[19] in 2013, it was concluded that the PEFR increases with an increase in height and weight
Summary
Pulmonary function tests (PFTs) are the diagnostic tests that aid in diagnosing and monitoring patients suffering from respiratory diseases. While performing Peak Expiratory Flow Rate(PEFR), patients are asked to perform an inspiration to achieve maximum lung volume, and make a quick forceful exhalation so that maximum possible amount of air from the lungs is removed.[1] The clinical use of PEFR requires a comparison with normative /standard data e.g. for asthma, flow limitation is diagnosed objectively if PEFR is < 80% of the normal or reference value.[2] Spirometry is the first and most commonly done lung function test This test quantifies the state of the respiratory system and aid in the management of respiratory tract illnesses in pediatric practice. Conclusion: The correlation of height and weight with PEFR values among urban and rural children was found to be highly significant
