In the case of pediatric bradycardia, when should CPR be initiated?

In pediatric patients, the threshold for initiating CPR in cases of bradycardia is critical to ensure timely intervention. The correct threshold for starting CPR is when the heart rate falls below 60 beats per minute (bpm). At this rate, there is a significant risk of decreased cardiac output and compromised perfusion, leading to potential cardiac arrest if not addressed promptly.

When the heart rate drops to this level, the effectiveness of the heart's ability to pump blood is reduced, which can lead to life-threatening situations. The pediatric population is particularly sensitive to bradycardic events, and maintaining an adequate heart rate is vital for sustaining organ function. Hence, recognizing the need for CPR in these circumstances is crucial for providing the appropriate level of care.

Lower heart rate thresholds, such as those stated in the other choices, do not align with the current guidelines for pediatric resuscitation and may delay critical intervention when the patient is in distress. Therefore, understanding that the initiation of CPR should occur when the heart rate is below 60 bpm helps ensure timely lifesaving measures for pediatric patients.
