Lung function tests in Rajasthani subjects.

Various lung volumes and ventilatory tests (TV, ERV, IC, MV, MVV, VC, FEV1, MMFER and PEFR) were determined and BR, DI and AVI (Air velocity Index) calculated in 241 Rajasthani subjects of either sex ranging from 17 to 40 years of age. Most of the values (Mean +/- SEM) are higher in males than in females, and also higher in the younger age groups (17 to 27 years) than in the older age groups (28 to 40 years) for the same sex.
