Abstract

Heart rate (HR) and blood oxygen saturation (SaO2) were monitored before and during clinically indicated MR examinations of newborns to (a) identify any temporal relationship between MR scanning and vital sign fluctuations and (b) assess the reliability of SaO2 monitoring of dynamic changes. Fluctuations in HR (but not in SaO2) that are temporally linked to the MR image acquisition occur in most neonates during routine clinical MR examinations.

摘要

在对新生儿进行临床指征性磁共振成像（MR）检查之前及检查期间，对心率（HR）和血氧饱和度（SaO2）进行监测，目的是：（a）确定MR扫描与生命体征波动之间是否存在任何时间关系；（b）评估动态变化中SaO2监测的可靠性。在大多数新生儿的常规临床MR检查期间，与MR图像采集在时间上相关的HR波动（而非SaO2波动）会出现。
