[Standard values of lung function diagnostics in children (author's transl)].

A joint study of 7 laboratories was initiated for the determination of standard function values in childhood. The sample included 3500 children. The vital capacity, forced expiratory volume, residual capacity, total capacity and work of breathing were determined and normal values calculated. These parameters were correlated with body height, body surface area, body weight and age. For an easy estimation of the predicted values regression formulas of the measured function are elaborated.
