Two indicators of effective newborn resuscitation that would prompt continuing advanced interventions, and what is the typical next step if heart rate remains <60 bpm after initial ventilation?

• A. Improvement in oxygen saturation alone.
• B. Heart rate improving to 70 bpm but color remains pale.
• C. Improvement in color, tone, or heart rate >60 bpm with ongoing ventilation; if HR remains <60 bpm after 30 seconds of effective ventilation, start chest compressions with a 3:1 compression-to-ventilation ratio and give epinephrine per protocol.
• D. Delay in action until after 2 minutes.

Answer: (C)

In newborn resuscitation, perfusion is monitored mainly through heart rate and signs of circulation such as color and tone. If ventilation is effective and you see improvement—heart rate rising above 60 bpm or the baby showing better color and tone—this means ventilation is successfully supporting circulation, so you continue with ongoing ventilation and monitoring rather than escalating interventions.

If, after 30 seconds of effective ventilation, the heart rate remains below 60 bpm, that's a sign perfusion is not adequate yet. The next step is to begin chest compressions using a 3:1 compression-to-ventilation ratio and administer epinephrine per protocol. This combination increases blood flow to the heart and brain when ventilation alone isn’t restoring adequate perfusion.

Why other scenarios aren’t as appropriate: improvement in oxygen saturation alone or color/tone changes without a heart rate above 60 don’t guarantee adequate perfusion, and delaying action until later steps risks worse outcomes.
