During pediatric CPR decision criteria, a pulse rate of less than what value with signs of poor perfusion indicates CPR should be initiated?

• A. <50
• B. <70
• C. <60
• D. <80

Answer: (C)

In pediatric CPR decision criteria, the key trigger to start chest compressions is a pulse rate that is too slow to sustain adequate perfusion, specifically under 60 beats per minute, when there are signs of poor perfusion. A heart rate this low means the cardiac output isn’t enough to keep tissues and organs well perfused, so external chest compressions are needed to maintain circulation while you address breathing, airway, and any reversible causes.

Signs of poor perfusion to look for include altered mental status, cool or mottled skin, delayed capillary refill (often more than 2–3 seconds in children), and a weak or absent central pulse. When the pulse is under 60/min with these signs, initiate CPR immediately to restore perfusion.

Options with higher or lower thresholds don’t align with this guideline. A pulse under 60 is the accepted tipping point; thresholds like 50 or 70 or 80 would not match the standard decision rule, which emphasizes starting compressions promptly at or below 60 when perfusion is inadequate.
