Abstract: Objective The aim of this cross sectional study was to study Pulmonary Function Test (PFT) parameters in Indian adults between age group 20 to 40 years, and to compare with the prediction equations issued by European Community for steel and Coal (ECSC). Method PFT parameters Forced Vital capacity (FVC), Residual volume (RV), Total Lung Capacity (TLC), Maximal Expiratory Pressure (MEP), Maximal Inspiratory Pressure (MIP), and Airway Resistance (Raw) were determined in 381 healthy non smokers of either sex between the age group 20 to 40 years residing in Marathwada region. The parameters were recorded using Medgraphics Body Plethysmograph, Elite DX Model No - 830001-005. Results For males, the differences in means of our and predicted values in liters for FVC, RV, TLC, MEP, MIP and Raw are 4.52 and 4.54, 2.00 and 1.69, 6.09 and 6.53, 157.09 and 196.22, -108.68 and –124.77, 1.19 and 2.24 respectively. For Females, the differences in means of our and predicted values in liters for FVC, RV, TLC, MEP, MIP and Raw are 2.59 and 3.49, 2.16 and 1.34, 4.68 and 4.86, 45.69 and 160.29, -65.16 and –91.76, 1.03 and 1.79 respectively. Conclusion Healthy Indians had consistently lower values of FVC, TLC, MEP, MIP and Raw, but higher values of RV than the ECSC recommendations in either sex. The ECSC recommended prediction equations may not be used for the Indian population. Population specific prediction equation should be derived for the Indian population after a large scale study.
