Comparative Study of Circadian Rhythm of Peak Expiratory Flow Rate in South Indian Healthy Females and Asthmatic Females

Abstract

AIM AND OBJECTIVESCross-sectional study to compare the peak expiratory flow rate with the help of "Mini-Wright" peak flow meter among females, normal healthy subjects and subjects who are asthmatics of age group 20-40 years. METHOD60 adult females of age group 20-40 years (30-Healthy and 30-Asthmatics) for whom baseline pulmonary function testing was done to differentiate normal and asthmatic. All cases were clinically examined to rule-out any obvious cardiopulmonary diseases. Subjects were provided one mini Wright's peak expiratory flow meter, were individually trained for measuring their own PEFR in L/min and were instructed to record the readings with Wright's portable peak
