FIGURE 1.

HeRO (Heart Rate Observation) monitor screen shot from an infant with sepsis. The top tracing shows the trend in the HeRO score over the last 5 days. The bottom tracing shows the last 30 minutes of heart rate. Clinicians can see the current HeRO score displayed at the top right, compare it with the previous 5-day trend, and scroll through to see 30-min heart rate (HR) tracings. In this case, the HeRO score had risen from a baseline of 1 to 2 for several days, eventually reaching a peak of >5. At the time indicated by the vertical line, the HeRO score was 3.34 and rising, and the 30-min HR tracing shows an abnormal pattern of few accelerations and numerous decelerations. The infant was diagnosed with Klebsiella septicemia (positive blood and urine cultures).
