To study the sequential changes in SpO2 values in newborns delivered in a teaching hospital in India.
Full-term infants born by normal vaginal delivery to registered mothers at KLE University Hospital, Belgaum with birth weight more than 2,500 g, no congenital anomalies and who had received only routine care at birth were included in the study. After delivery, newborn infants were placed on a resuscitation trolley under a radiant warmer; the oxygen saturation sensor was attached (Nellcor DURA-Y multisite oxygen sensor) and then connected to the monitor (Planet 55 multiparameter recorder).
The mean (SD) gestational age of infants included in the study was 38.8 (1.1) wk and birth weight was 2,800 (300) g. The median (IQR) oxygen saturation level (SpO2) at 2 min of age was 69 % (68 %-79 %). The median level of SpO2 at 90 % and 95 % saturation was attained at 6.5 min and at 11 min of life, respectively.
Infants delivered in resource poor facilities of developing countries take 11 min to reach 95 % saturations after birth but they are within the reference range values of Neonatal Resuscitation Program 2010 guidelines.
研究印度一家教学医院中新生儿血氧饱和度（SpO2）值的连续变化情况。
纳入在贝尔高姆市KLE大学医院经正常阴道分娩出生的足月婴儿，其母亲已登记，出生体重超过2500克，无先天性异常，且出生时仅接受常规护理。分娩后，将新生儿置于辐射保暖台的复苏推车上；连接氧饱和度传感器（Nellcor DURA - Y多部位氧传感器），然后与监护仪（Planet 55多参数记录仪）相连。
纳入研究的婴儿平均（标准差）胎龄为38.8（1.1）周，出生体重为2800（300）克。出生2分钟时血氧饱和度水平（SpO2）的中位数（四分位间距）为69%（68% - 79%）。分别在出生6.5分钟和11分钟时达到90%和95%饱和度的SpO2中位数水平。
在发展中国家资源匮乏的医疗机构中出生的婴儿出生后需11分钟才能达到95%的饱和度，但他们仍在2010年新生儿复苏项目指南的参考值范围内。
