OBJECTIVE: In this study of preterm neonates of 95%. The room air group was initially resuscitated with 21% oxygen, which was increased to 100% oxygen if compressions were performed or if the heart rate was <100 beats per minute at 2 minutes of life. Oxygen was increased in 25% increments if pulse oxygen saturation was <70% at 3 minutes of life or <80% at 5 minutes of life. RESULTS: Twenty-three infants in the oxygen group (mean gestational age: 27.6 weeks; range: 24-31 weeks; mean birth weight: 1013 g; range: 495-2309 g) and 18 in the room air group (mean gestational age: 28 weeks; range: 25-31 weeks; mean birth weight: 1091 g; range: 555-1840 g) were evaluated. Every resuscitated patient in the room air group met rescue criteria and received an increase in the fraction of inspired oxygen by 3 minutes of life, 6 patients directly to 100% and 12 with incremental increases. Pulse oxygen saturation was significantly lower in the room air group from 2 to 10 minutes (pulse oxygen saturation at 3 minutes: 55% in the room air group vs 87% in the oxygen group). Heart rates did not differ between groups in the first 10 minutes of life, and there were no differences in secondary outcomes. CONCLUSIONS: Resuscitation with room air failed to achieve our target oxygen saturation by 3 minutes of life, and we recommend that it not be used for preterm neonates.
