Summary
Hydrogen peroxide (H2O2)
production in exhaled air was measured in ventilated preterm newborns at
5, 24 and 48 hours after delivery, using originally designed method of
exhaled breath condensate (EBC) collection. H2O2
production in expired gas was 812±34 pmol/20 min during the first
measurement and then declined to 389±21 at 24 hours and 259±26 pmol/20 min
at 48 hours.
