[Pulmonary function in normal Japanese children 6 to 16 years of age].
We measured pulmonary function on 182 healthy Japanese children 6 to 16 years of age living in the Tokyo area. Static lung volumes, RV/TLC (%), FRC/TLC (%), FVC, FEV1, FEV1/FVC (%), MMFR, MVV, f, VE and VO2 were measured. Multiple regression equations were obtained and the results were compared with those derived from the other equations (Kanagami (1958), Ishida (1955]. The predicted values were about 10 approximately 25% higher with our equations than those obtained from the other equations which were made more than 30 years ago. These differences were attributed to the recent improvement in growth of the Japanese children. For this reason we think it is better now to adopt new equations for the prediction of normal values in Japanese children.
