How should heart rate be assessed in a newborn during resuscitation?

• A. Auscultate heart rate only
• B. Evaluate heart rate via auscultation or at umbilical cord
• C. Measure heart rate with ECG monitor
• D. Estimate heart rate by perfusion index

Answer: (B)

In newborn resuscitation, you need a fast, reliable way to know the heart rate to decide whether to ventilate or start compressions. The quickest and most practical approach is to assess the heart rate by auscultation of the chest or by palpating the umbilical cord. Both methods can be done immediately at the bedside and provide an immediate estimate of how fast the heart is beating, which is essential for guiding the next steps in resuscitation. Using auscultation with a stethoscope on the chest is a direct read of the heart’s activity and is widely taught as the primary bedside method because it gives a real-time rate. If the chest sounds are hard to hear or a clearer read is needed, evaluating the heart rate at the umbilical cord serves as an alternative quick check, especially when access to the chest is limited or rapid assessment is required. While an ECG monitor can offer precise heart-rate data, it may not be immediately available or fast enough to guide the initial actions, and waiting for full monitor setup can cause delays. Estimating heart rate by perfusion index, on the other hand, is not a direct, reliable measure of heart rate and should not be used as the primary method during resuscitation. So, the best practice is to evaluate heart rate via auscultation or at the umbilical cord for the fastest, most reliable immediate assessment, with ECG as a helpful adjunct when available and feasible.
