What is the primary indication for delivering chest compressions in infants during CPR?

The primary indication for delivering chest compressions in infants during CPR is a heart rate below 60 beats per minute with poor perfusion. This threshold is critical because a heart rate below 60 bpm in an infant indicates severe bradycardia, which can compromise blood flow and oxygen delivery to vital organs. When an infant exhibits poor perfusion—evidenced by signs such as mottled skin, weak pulses, or altered consciousness—immediate chest compressions are necessary to restore circulation and improve oxygenation.

In infants, their physiological response to hypoxia or inadequate circulation can deteriorate rapidly, so recognizing the need for chest compressions at this heart rate is vital for effective resuscitation. The guidelines emphasize that addressing bradycardia effectively corresponds with the delivery of appropriate CPR interventions to improve the infant's chance of survival and mitigate potential neurological damage from lack of oxygen.
