[Spirometric studies in clinically healthy metallurgy workers. II. Reference values of basic respiratory indicators].

In a group of 520 clinically healthy men employed in metallurgy, predicted values in the function of age, height and body weight were set up by multiple regression for VC, FEV1 RV, ERV, FRC, RV%TLC and for FEV1%VC in the function of age and for TLC in the function of height. In the tables are given predicted values for VC, FEV1, RV%TLC (based on equations of regression) for 9 intervals of age, height and body weight.
