Abstract :

Early detection of chronicobstructive pulmonary disease in asymptomatic smokers by using spirometry an observational study the effect of screening spirometry in smoking cessation, delaying the onset of severe COPD, preventing morbidity and mortality, and ultimately decreasing the prevalence of COPD. In the present study it was observed that, out of a total of 370 subjects, 175 were more than 40 years of age which constitute around 47.29%, where as those who are less than or equal to 40 years age constituted a 52.70%. The mean age was 40.14 ± 5.47. Overall the mean smoking index in 370 subjects was 300.55 ± 219.48.In subjects >40 years of age mean SI was 371.88 ± 249.49 and in subjects ≤40 years it was 326.53 ± 164.59. Overall airway obstruction was seen 42 subjects i,e., 11.35%.Mild obstruction (GOLD stage 1) was seen in 31 subjects which corresponds to 73.80%.Moderate obstruction (GOLD stage 2)was seen in 11 subjects which constitutes 26.19%.Airway obstruction was noticed in 24 subjects out of a total of 121 subjects with smoking index >200, which corresponds to 19.8%.In smokers more than 40 years of age and with smoking index less than 200 (n=97), 10 had mild obstruction (GOLD 1) and 1 had moderate obstruction. In smokers less than 40 years of age and smoking index more than 200 (n=43), 4 had mild obstruction and 2 had moderate obstruction. In smokers more than 40 years of age and with smoking index more than 200 (n=78), 10 had mild obstruction (GOLD 1) and 8 had moderate obstruction. In smokers less than 40 years of age and smoking index less than 200 (n=152), 7 had mild obstruction.
