A STUDY OF PEAK EXPIRATORY FLOW RATE IN HEALTHY ELDERLY PUNJABI FEMALES
Journal Title: International Journal of Basic and Applied Physiology - Year 2015, Vol 4, Issue 1
Abstract
Background: Age reduces the ventilatory capacity of lung/chest wall system and is thus expected to affect the PEFR. Peak expiratory flow rate (PEFR) is a relatively simple test to administer and is fairly repeatable. The present study was conducted to study the effect of various factors like age, height, weight, Body Surface area (BSA) and Body Mass Index (BMI) on PEFR in healthy elderly females and to determine the normal PEFR values to establish local reference standards. Method: The PEFR was measured in 50 healthy females in the age group of 65 - 94 years of rural areas of Patiala district using the mini Wright’s peak flow meter in standing position. Best out of three trials were recorded. It’s Correlation with age, anthropometric variables, BMI and BSA was calculated Results: The mean PEFR in the age group of 65-74 years for females was highest and it declined with increase in age. The correlation of PEFR with age was negative and highly significant. It has positive correlation with height and non-significant correlation with weight, Body Mass Index (BMI) and Body Surface Area (BSA). Conclusion: It was concluded that with advancing age, PEFR declines. Taller subjects have more PEFR in comparison to subjects having shorter height.
