The aim of the present study was to correlate the pulmonary function test (PEFR, FEV1) with pack years in smokers. Descriptive and Co relational design was selected for the study. Samples of 30 patients who smokes and regular to the therapeutic clinic for check-up were selected by Purposive sampling technique. Computerized Spirometer was used to assess the pulmonary lung function test (FEV1 and PEFR). All patients falling under the inclusion criteria were given orientation regarding spirometric lung function test. Consent was obtained from each subject after giving assurance of confidentiality. FEV1 and PEFR values were obtained by using spirometer with pack years. The obtained data was analyzed using descriptive and inferential statistics and interpreted in terms of objectives and hypothesis of the study. The level of significance was set at 0.05 levels.


For FEV1 value mean was 35.26 (SD=11.305) and pack year mean was 37.06 (SD=6.363) with an ‘r’ value of -0.760 and it is in negative fairly high degree of correlation. The obtained P value is 0.000 and thus the correlation is highly significant at 0.05 level of significance. The mean value for PEFR was 30.86 (SD=7.31) and the mean of pack year was 37.06 (SD=6.363) with an ‘r’ value of -0.792 and it is negative fairly high degree of correlation. The P value obtained is 0.000 and thus the correlation obtained is highly significant at 0.05 level of significance. Hence the study concludes that as the pack year increases there is decline in the PEFR, FEV1 values.


The study findings indicate that there was a marked difference in the FEV1 and PEFR values as the pack year increases. Hence early cessation of smoking is very essential in preventing complication.
