Delivery room oxygen physiology and respiratory interventions for newborns with cyanotic congenital heart disease

Objective To characterize pulse oxygen saturation (SpO 2 ) trajectories and respiratory interventions after birth for newborns with cyanotic congenital heart disease (CCHD). Study design Retrospective single-site study of newborns ≥32 weeks gestation with CCHD: single ventricle with critical aortic obstruction (SV-CAO), critical pulmonic obstruction (CPO), transposition of the great arteries (TGA). Minute-to-minute SpO 2 values and respiratory interventions were summarized and compared. Results Two hundred infants were enrolled. SpO 2 at each minute differed across groups ( p
