To determine growth patterns of the lung and airways in adolescents, we analyzed maximal expiratory flow-volume curves, closing capacity, and residual volume.
They were obtained every 6 mo for up to 7 yr in 430 boys and 125 girls (11-19 yr), of whom 143 boys and 36 girls were classified as symptomatic; symptoms were most often minor and limited to childhood.
Development of flows vs. volumes was used to investigate growth of the airways relative to lung size.
A model of isotropic growth of the airways and air spaces (J. Appl.
Physiol. 65: 822-828, 1988) was modified for increasing elastic recoil pressure with growth.
