Abstract :

Early detection of chr.obstrucive 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.
