Final answer:
Stop neonatal chest compressions when the heart rate is over 100 bpm or if the infant displays signs of effective circulation such as a strong cry.
Step-by-step explanation:
When performing cardiopulmonary resuscitation (CPR) on a neonate, you should stop chest compressions when the infant's heart rate is greater than 100 beats per minute (bpm). This guidance aligns with the principles of neonatal resuscitation and the Apgar score, which evaluates a newborn's transition from the womb, including heart rate and respiration as two of the most critical criteria. If an infant exhibits signs of effective circulation and adequate respiration, such as a robust cry, this may also indicate the possibility of discontinuing CPR.
