Foglia EE, et al. - Among infants born very preterm, researchers studied the impact of policy changes for pulse oximetry oxygen saturation (SpO₂) alarm limits on neonatal mortality and morbidity. The study sample consisted of infants born very preterm in the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network. In this retrospective cohort study, there were 3809 infants in 10 hospitals with an SpO₂ alarm policy change and 3685 infants in 9 hospitals without a policy change. For hospitals with a policy change, the odds of bronchopulmonary dysplasia were greater, but there was no difference for hospitals without a policy change. Findings suggested no association of changing SpO₂ alarm policies with reduced mortality or increased severe retinopathy of prematurity among infants born very preterm.
