Figure 6.
Box plots showing the difference in heart rate over time between the various devices (NeoBeat–ECG, n = 3953; PO–ECG, n = 1214; PO–NeoBeat, n = 2290). PO tends to underestimate HR the initial five-six minutes during resuscitation, whereas NeoBeat and gel-electrode ECG correlate well. PO, Pulse Oximetry. Dots represents outliers.
