Pulse oximetry is an imperative noninvasive tool to detect hypoxia. Signal extraction technology (SET)-based pulse oximeters recommended in neonates are expensive, while finger pulse oximeters are cheaper and widely available. Oxygen saturation (SpO) values and reliable saturation reading time of 30 neonates were obtained using MEDITIVE MPO-03 fingertip pulse oximeter and Masimo SET-Rad-97 pulse oximeter on the right hand and right foot. Bland-Altman technique, paired t-test and Pearson correlational analysis were used. There was a good agreement of paired SpO measurements between the two oximeters on right foot. The agreement limits and bias were -1.2% to 0.8%, -0.1% for right hand, and -0.7% to 0.7%, -0.01% for right foot, respectively with a confidence interval of 95%. The mean response time obtained for finger pulse oximeter on right hand and right foot was 66.4 ± 4.6 and 58.9 ± 5.0 and for SET-based pulse oximeter was 47.8 ± 2.9 and 48.3 ± 3.0 s, respectively. Finger pulse oximeters can be considered in low-resource settings on the foot of the neonate, with a response time of 59 s.
脉氧仪是检测缺氧的重要无创工具。推荐在新生儿中使用基于信号提取技术（SET）的脉氧仪，但价格昂贵，而手指脉搏血氧仪价格更便宜且广泛可用。使用 MEDITIVE MPO-03 指尖脉搏血氧仪和 Masimo SET-Rad-97 脉搏血氧仪，在新生儿右手和右脚分别测量了 30 例的血氧饱和度（SpO）值和可靠的 30 秒 SpO 读数时间。采用 Bland-Altman 技术、配对 t 检验和 Pearson 相关分析。右脚的两种血氧仪的 SpO 测量值具有良好的一致性。右脚的一致性限和偏差分别为-1.2%至 0.8%，-0.1%；右手分别为-0.7%至 0.7%，-0.01%；置信区间均为 95%。右手和右脚的手指脉搏血氧仪的平均响应时间分别为 66.4±4.6 和 58.9±5.0 s，SET 基础脉搏血氧仪的平均响应时间分别为 47.8±2.9 和 48.3±3.0 s。在资源有限的情况下，可以考虑将手指脉搏血氧仪用于新生儿足部，其响应时间为 59 秒。
