The 2025 AHA updated the Chain of Survival to apply to this group — no longer split by age or setting.
What is ALL cardiac arrests (adults, pediatric, and neonatal, in-hospital and out-of-hospital)?
The compression-to-breath ratio for a single rescuer performing CPR on a child or infant.
What is 30:2?
You should attach the AED as soon as this happens.
What is when it becomes available?

What is 1 second?
This is the first link in the Chain of Survival.
What is recognition of cardiac arrest and activation of emergency response?
When two rescuers perform CPR on a child or infant, the compression-to-breath ratio changes to this.
What is 15:2?
Before the AED analyzes the heart rhythm, you must make sure no one is doing this to the victim.
What is touching the victim?
After each compression, you must allow this to happen before the next compression.
What is full chest recoil?
This barrier device covers the victim's face and allows you to give rescue breaths safely.
What is a pocket mask?
If any of these is broken in the Chain of Survival, the victim's chance of a good outcome decreases.
What is a link?
For infant compressions, the 2025 AHA recommends this technique instead of the 2-finger technique.
What is the 2-thumb encircling hands technique (or heel of one hand)?
For children under 8 years old, this type of AED pads is preferred when available.
What are pediatric pads?
You should keep pauses in chest compressions to fewer than this many seconds.
What is 10 seconds?
For an INFANT, you cover both the mouth and this with your mouth to give a rescue breath.
What is the nose? (Yes, you cover their mouth and nose with your mouth if you don't have a pocket mask. Don't pinch their nose)
This link in the Chain of Survival refers to using an AED quickly.
What is rapid defibrillation?
Compress an infant's chest to approximately this depth.
What is 1.5 inches (4 cm), or one-third the chest depth?
After delivering an AED shock, you should immediately do this.
What is resume CPR (starting with chest compressions)?
When performing adult CPR, place the heel of your hand on this part of the chest.
What is the center of the chest (lower half of the sternum)?
This problem can occur when you give too many or too forceful breaths during CPR.
What is gastric inflation (over-ventilation)?
Care given after a successful resuscitation is called this, and it is the last link in the Chain of Survival.
What is post-cardiac arrest care?
For an unwitnessed pediatric arrest when you are alone, you should do this for about 2 minutes before leaving to call for help.
What is perform CPR?
This is what an AED analyzes to determine if a shock is needed.
What is the heart's electrical rhythm?
