Simple spirometry was done in 319 subjects consisting of smokers and non-smoking males and females of various age groups, VC, FEV1’ FEV1%, MBC, MMFR, FEF and PEFR were determined from forced expiratory spirogram. The data was computerised and statistically analysed. Ventilatory abnormalities were noted in smokers. The moderate smokers had values between those of non-smokers and the heavy smokers. Pulmonary function norms in Indians subjects are lower than in Western subjects. Pulmonary function norms are higher in Males when compared to Females, FEV1% being equal in both sexes. There is a positive correlation between pulmonary function para-meters and physical measurements, and negative correlation with age.
