Assessment of exhaled gases in ventilated preterm infants

Physiol Res. 2004;53(5):561-4.

Abstract

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.
