摘　　要：目的:探讨新生儿监护仪中脉搏灌注指数(PI)值的稳定性与血氧饱和度(SpO_(2))报警的关系,以期降低误报警率。方法:使用双血氧模块(模块1和模块2)监护仪同时监测新生儿身体的不同部位,以两个模块同时报警时认定为有效报警,而仅1个模块报警时,则认为无效报警。通过计算PI值的方差将PI值分为A类(数据无更新)、B类(数据变换更新)和C类(无数据),统计有效报警在3类情况中的分布情况。选取2023年5月11日至19日山西省儿童医院新生儿病区收治的18例新生儿进行监测,每例患儿平均监测7.3 h,对比双血氧模块监测的A类、B类和C类误报警率以及PI值与SpO_(2)报警的相关性。结果:模块1和模块2两个无创血氧模块监测到的有效警次数为41次,A类和C类误报警率均明显高于B类。模块1和模块2监测的PI值A、B、C类次数分别为6、34、1和8、30、3次,与SpO_(2)有效报警次数均呈弱相关(r=0.230、0.259,P<0.05),单因素二项逻辑回归SpO_(2)报警时PI值分类无法预测SpO_(2)报警。结论:PI值能够反映传感器采集到的数据不稳定时影响SpO_(2)的报警正确性,使用单SpO_(2)传感器采集到的PI值能够间接反映传感器采集到的数据不稳定时会影响SpO_(2)的报警正确性,而采用双血氧模块监护仪同时监测新生儿能够提高SpO_(2)报警准确性。Objective:To explore the relationship between the stability of the pulse perfusion index(PI)value and Pulse oximetry(SpO_(2))alarms in monitor for neonates,so as to reduce the false alarm rate.Methods:A monitor with dual blood oxygen module(Module 1 and Module 2)was used to simultaneously monitor different parts of neonates.If both modules alarmed simultaneously,it was considered as a valid alarm.If only one module alarmed while the others was normal,it was considered as an invalid alarm.The PI values were classified into A,B and C categories based on the calculated variance of PI values.The distribution of valid alarms in the three categories was analyzed by using statistical method.The eighteen neonates who admitted to the neonatal department of Shanxi Children's Hospital from May11,2023 to May 19,2023 were monitored,with an average monitoring time of 7.3 hours for each case.The false alarm rates of the monitor with dual blood oxygen module were compared among categories A,B and C,as well as the correlations between different PI values and SpO_(2) alarms.Results:The times of monitored valid alarm of two noninvasive blood oxygen modules(Module 1 and Module 2)were 41 times,and the false alarm rates of categories A and C were significantly higher than that of category B.The times of categories A,B and C of the monitored PI values of Module 1 and Module 2 were respectively(6,34,1)and(8,30,3),which appeared weak correlation with the times of valid alarm of SpO_(2)(r=0.230,0.259,P<0.05).The result of univariate binary logistic regression indicated PI value could not predict SpO_(2) alarms in SpO_(2) alarm.Conclusion:PI value can reflect the affected accuracy of SpO_(2) alarm when the data that are collected by prober are instability.The PI value that is collected by single SpO_(2) prober can indirectly reflect that the instable data of collection can affect the correctness of SpO_(2) alarm,while the simultaneous monitor of adopting monitor with dual oxygen module can improve the accuracy of SpO_(2) alarms in monitori
