Background and purpose: Spirometry is a powerful method in assessment and management of many respiratory disorders. Technological improvement has made it a reliable, relatively simple and available method in clinical settings. Native spirometric standard values are necessary for the interpretation of pulmonary function test. In this study, important spirometric values (FVC,FEV1, FEV1/ FVC ,FEF25-75 ) of healthy adults > 18 years old in Sari city were compared with those of predicted standard equations to determine the nearest values.
Materials and Methods: Five hundred and seven healthy adults (245 males, 262 females) selected by random sampling, with no previous history of smoking and without chronic or acute respiratory problems were subjected to spirometry with calibrated Fukudo Sangyo spirometer. The methodological guidelines of the American Thorasic Society were observed to perform spirometry. The results were analyzed by SPSS, paired t- test and Pearson correlation.
Results: The results indicated that the mean values of males are more than those of females .The highest values are from the 20-30 years age group.The correlation coefficient of height with the measured values is very high (99% confidence interval) but for the weight is low. The nearest standard predicted values to the measured values were from Eccs.
Conclusion: According to the results and correlation coefficient test, measured values have the highest correlation with Eccs predicted values with 99% confidence interval and the Eccs standard seems to be the most proper standard for Sari community, more researches are recommended though.
