Z\u2010score values for functional residual capacity (FRC), residual volume (RV), FRC\/total lung capacity (TLC), and RV\/TLC were significantly higher in infants with CDH and PH compared to those without PH. Z\u2010score values for forced flows including forced expiratory volume in the first 0.5\u2009sec (FEV0.5) and FEV0.5\/forced vital capacity were significantly lower in infants with CDH and PH compared to those without PH. For 29 infants studied on \u22652 occasions, the slopes of FRC, RV, and TLC versus length were significantly higher in those with persistent PH compared to those without.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Infants with CDH and persistent PH demonstrate greater airspace overdistension with growth compared to those without.
