    Infants <26 weeks’ gestation managed with HFJV showed lower peak PaCO2 and less fluctuation associated with survival without severe IVH.

  • 2

    Higher peak PaCO2, greater fluctuations, and deviation from target levels were linked to lower odds of survival and absence of severe IVH.

  • 3

    Proposed cut points for PaCO2 control include peak <65 mm Hg, fluctuation <25 mm Hg, and deviation <15 mm Hg.

  • 4

    The study emphasizes PaCO2 stability as crucial for extremely preterm infants, rather than solely targeting permissive hypercapnia.

  • 5

    The cohort studied had a mean gestational age of 24.3 weeks and birthweight of 656 g, reflecting contemporary neonatal care practices.
