Studies report that ECG measures newborns’ heart rate (HR) more quickly1 ,2 and accurately3 than pulse oximetry (PO) in the delivery room (DR). In these studies, separate ECG and PO monitors were applied. The Philips IntelliVue X2 monitor (Philips, Eindhoven, Netherlands) incorporates ECG and Masimo PO technology (Masimo, Irvine, California, USA) and has a portable unit that may be used in the DR. This monitor displays HR faster when the ECG leads are connected to the machine before application to the infant.4 We wished to determine whether the order of application of ECG and PO affected how quickly …
