Age-based comparison
Select an age group to compare rate, depth, compression-to-ventilation ratio, and current hand-technique guidance.
Lay rescuers recognize arrest by unresponsiveness and absent or abnormal breathing such as gasping. Healthcare professionals may check a pulse for no more than 10 seconds.
Conventional CPR with breaths is preferred for pediatric cardiac arrest because respiratory causes are common. If a lay rescuer cannot or will not give breaths, compression-only CPR is reasonable.
The 2025 pediatric BLS guideline eliminated the two-finger infant compression technique because it was ineffective at consistently achieving proper depth.
Major 2025 updates
The 2025 AHA Guidelines were released October 22, 2025. These are selected high-yield BLS changes, not a substitute for the complete guideline.
Use repeated cycles of 5 back blows followed by 5 abdominal thrusts, starting with back blows, until the object is expelled or the person becomes unresponsive.
Use repeated cycles of 5 back blows followed by 5 chest thrusts. Do not use abdominal thrusts on an infant.
Use the heel of one hand or the two-thumb encircling-hands technique. The two-finger technique was removed.
A universal Chain of Survival now spans pediatric and adult arrest, and opioid antagonists such as naloxone are incorporated into BLS pathways for suspected opioid emergencies.
