[Basal pulmonary function studies (FVC, FEV) in a selected child population].

: This is a study of the ventilatory function (FVC, FEV1) by dry spirometer Vitalograph in 1566 children of both sexes with ages ranging from 7 to 14; 1156 children (73.6 per 100) were selected as reference population. Height was the biometric parameter with the greatest correlation to the functional variables studied in both sexes. Significant differences were observed in functional variables between male and female subjects. Multiple and simple linear prediction equations and percentiles tables for each sex are presented. The results of the present study are compared with those of previously published of children.
