Abstract:
Objective To establish the reference ranges of preductal oxygen saturation (SpO2) and heart rate (HR) for healthy neonates in 10 minutes after birth. Methods SpO2 and HR recordings of 203 term neonates (vaginal group:n=97 and ce-sarean group:n=106) with regular respiratory pattern were evaluated. 10th-95th percentile charts of SpO2 and HR from 1 minute to 10 minutes after birth were drawn. Results The SpO2 of P10, P50 and P95 at 1 minute after birth was 62%, 71%and 85%respec-tively. The heart rate of P10, P50 and P95 at 1 minute after birth was 66 bpm, 98 bpm and 126 bpm respectively. The median time for SpO2 to reach 90%was 5 minutes. The rising trend of HR was evident during 1-5 minutes after birth, and then the HR leveled off. Conclusions The status of newborn can be assessed using the charts of SpO2 and HR combined with clinical manifestations. The oxygen intervention should be used with care to avoid damage caused by hyperoxemia and hypoxemia.
