ABSTRACT

Pulmonary function test are difficult to perform standardize and evaluate and there are several reference values. The objective of this study was to analyze the values of the forced vital capacity (FVC) and the forced espiratory flow in the first second (FEF1) in 100 normal men with a mean age of 24.3 years.
The coefficient of determination (R²) for the FVC and height was 0.34 (p ‹ 0.001) and for FEF1 and height 0.31 (p ‹ 0.0001). Multiple regression analysis with height, weight, age and cardiothoracic index, showed an increase of R² to 0.38 for FVC and 0.33 for FEF1. The values estimated with the regression equations are lower in this study than those reported in the literature for FVC and similar for FEF1. For our country, it is necessary to reconsider the use of the reference tables and equations that come with the modern computers currently used for the pulmonary function tests.
