CPR for Adults, Children and Infants
The purpose of CPR is consistent across ages: support circulation and oxygen delivery when a person is unresponsive and not breathing normally. The physical technique changes because an infant’s body is not a smaller adult body, and children vary widely in size.
Age-specific training teaches hand or finger position, compression depth, ventilation seal, response when alone and AED pad considerations. Learners should practice each population on the correct manikin rather than relying on a verbal comparison.
A child’s size falls between examples
A learner asks whether to use one or two hands on a larger child. The instructor focuses on achieving the trained depth with control rather than treating age as the only clue.
Body size and effective technique both matter within the age-based framework.
Keep the decision simple and adapt the technique
Recognize unresponsiveness and abnormal breathing, activate 911 according to the trained sequence, begin age-appropriate CPR and use an AED as soon as available. Follow dispatcher and device prompts.
Do not practice full compressions on a person, use adult force on an infant, delay action while debating exact age or place AED pads so they touch.
Adult technique
Two-hand compressions are generally used at the center of the chest. In a stressful scene, this is where a small decision can either preserve momentum or create a distracting delay.
Stack shoulders and allow full recoil. State the action aloud, assign it to one person and confirm that it happened. A useful response is controlled and visible rather than dramatic.
Child technique
One or two hands may be appropriate depending on size and rescuer control. This principle becomes easier to remember when it is connected to a specific cue.
Use the method that achieves trained quality. Describe what you can see, hear or verify without guessing at the cause. Then use current training and live instructions to decide what comes next.
Infant technique
Finger or encircling-thumb methods use different landmarks and force. The safest boundary is the point at which basic first aid stops and professional assessment begins.
Practice on an infant manikin. Do not let a familiar-looking symptom create false reassurance. When the pattern is severe, changing or uncertain, early escalation is the practical choice.
A practical age-specific cpr checklist
Use this list for preparation and review. During a real emergency, follow 911 instructions and current training.
- Stack shoulders and allow full recoil.
- Use the method that achieves trained quality.
- Practice on an infant manikin.
- Use appropriate equipment and prevent pad contact.
- Use appropriate training devices and objective feedback within a structured course.
- Schedule short reviews and scenario practice instead of waiting for an emergency.
- Confirm that contact information, supplies and roles are current.
- Record one gap and assign the correction before the next practice session.
Breaths and AEDs
Seal and pad placement must fit the body. Preparation reduces the number of decisions that must be invented during the emergency.
Use appropriate equipment and prevent pad contact. Equipment, roles and communication should support the skill rather than compete with it. Afterward, document any gap that should be corrected before the next event.
Connect knowledge to physical practice
Reading can explain a sequence but cannot verify timing, positioning or equipment use. The distinction matters because a responder works from observable facts, not a private diagnosis.
Use appropriate training devices and objective feedback within a structured course. Keep the next step plain enough that another bystander can repeat it back. That protects the urgent priority while professional help is being activated.
Refresh the skill deliberately
Memory and confidence can fade when a skill is never retrieved under realistic conditions. In a stressful scene, this is where a small decision can either preserve momentum or create a distracting delay.
Schedule short reviews and scenario practice instead of waiting for an emergency. State the action aloud, assign it to one person and confirm that it happened. A useful response is controlled and visible rather than dramatic.

Use this comparison to connect an observable cue with a safe next step and a clear boundary.
| Decision point | Risk to avoid | Prepared response |
|---|---|---|
| Adult technique | Two-hand compressions are generally used at the center of the chest. | Stack shoulders and allow full recoil. |
| Child technique | One or two hands may be appropriate depending on size and rescuer control. | Use the method that achieves trained quality. |
| Infant technique | Finger or encircling-thumb methods use different landmarks and force. | Practice on an infant manikin. |
| Breaths and AEDs | Seal and pad placement must fit the body. | Use appropriate equipment and prevent pad contact. |
| Connect knowledge to physical practice | Reading can explain a sequence but cannot verify timing, positioning or equipment use. | Use appropriate training devices and objective feedback within a structured course. |
Build a response people can actually use
A short tabletop exercise can expose confusion without asking anyone to act out an injury. Use a manikin or training device when physical skill practice is appropriate. Never rehearse an emergency maneuver on an unsuspecting person, and stop any exercise that becomes unsafe.
- Adult technique: Remove one helper from the scenario and decide which priority must still be protected.
- Child technique: Add noise or limited space, then practice giving one clear instruction at a time.
- Infant technique: Identify the exact moment when first aid reaches its limit and professional guidance is needed.
- Breaths and AEDs: Finish with the location, the person’s condition, actions taken and any meaningful change.
- Connect knowledge to physical practice: Name the observable cue, the first action and the person responsible for calling 911.
Run the scene once with the supplies and people normally available. On the second pass, change one condition: the phone cannot connect immediately, the usual kit is missing, the space is crowded or the person cannot answer questions. The purpose is not to invent advanced treatment. It is to preserve scene safety, emergency activation, the highest-priority first-aid action and a clear handoff.
Debrief with evidence instead of impressions. Ask what was noticed first, how long it took to assign the emergency call, which words caused confusion and whether anyone crossed a training boundary. Record one correction, give it an owner and repeat the drill after the correction is made. That is how a reading exercise becomes a practical readiness improvement.
Where a reasonable response can go off track
Fast care is not the same as rushed care. A useful response protects the first life-saving priority while avoiding actions that add injury, delay or confusion. Review these traps during practice so the correction is available before stress narrows attention.
Breaths and AEDs
Another trap is allowing the search for equipment or certainty to replace the priority already in front of the responder. Seal and pad placement must fit the body. The safer correction is specific: Use appropriate equipment and prevent pad contact. Confirm the action aloud and keep watching for a change that requires 911, CPR or another trained response.
Connect knowledge to physical practice
Teams also lose time when several people start the same task while no one owns the emergency call or handoff. Reading can explain a sequence but cannot verify timing, positioning or equipment use. The safer correction is specific: Use appropriate training devices and objective feedback within a structured course. Confirm the action aloud and keep watching for a change that requires 911, CPR or another trained response.
Refresh the skill deliberately
The appearance of improvement can create false reassurance when no one keeps monitoring the original warning signs. Memory and confidence can fade when a skill is never retrieved under realistic conditions. The safer correction is specific: Schedule short reviews and scenario practice instead of waiting for an emergency. Confirm the action aloud and keep watching for a change that requires 911, CPR or another trained response.
Practical questions
What if I do not know the person’s exact age?
Use body size, dispatcher guidance and your current training rather than delaying CPR.
Is compression-only CPR the same for every emergency?
No. Rescue breaths are especially important for infants, children and oxygen-related causes; follow training and dispatcher guidance.
Does one training session complete the program?
No. Readiness also depends on accessible supplies, current procedures, practice, maintenance and follow-through after incidents and drills.
Who should own the corrective action?
Assign a named role or position, a deadline and a verification step. A general reminder is easy to lose.
