Lung function in childhood. 2. Thoracic gas volumes and helium functional residual capacity measurements in healthy children

Br J Dis Chest. 1975 Apr;69(2):118-24.


The helium dilution functional residual capacity (FRC) and the total gas volume by plethysmograph (TGV) were measured on 236 healthy London schoolchildren. There was no difference between the results obtained by the boys and girls. The results of the TGV were higher than the FRC values. From the results, normal data charts have been devised for clincial use.
