    Dr. Elizabeth Hartnett reviews the latest clinical studies on oxygen management in retinopathy of prematurity (ROP) and concludes that we do not know the best oxygen levels for reducing ROP and pulmonary morbidity, as well as increasing survival and cognitive development for extremely preterm infants. Because many nurseries do not obtain routine blood gas measurements, assessments are made based on SaO2 and not on PaO2. A recent meeting among neonatologists at the Pediatric Academic Societies meeting, suggest agreement in avoiding high oxygen at birth (resuscitation with 30% FiO2), and many targeted higher oxygen saturation (88%-95% SaO2 for the first few weeks of life, trying to avoid swings in oxygen) until more is known on morbidity and mortality with low SaO2 targets.
