The respiratory system changes with age and understanding these changes helps detect and prevent respiratory dysfunctions in the elderly. Pulmonary function, as measured by spirometry is an important predictor of morbidity and mortality of elderly persons. The aim of present study was to see the effect of aging on pulmonary functions in different age groups of healthy people in western Rajasthan. The study included 150 subjects of different age from 20 years and above. Subjects were divided in six groups depending on their age. The results showed that values of FVC, FEV 1 , FEF 2 5 - 7 5 % , PEFR and MVV were observed to be higher in the age group of 20 -30 years. Data for FEV 1 /FVC ratio shows that up to 50 years of age this ratio is not much different, but later on in 60 -80 years age group D, group E, group F. Differences in the respiratory patterns of healthy adults and the elderly, suggesting that age impacts on lung function.
