Have you ever wondered how CPR differs for adults, children, and infants? I still remember the first time I saw CPR demonstrated at a community health workshop. It struck me how critical it is to know the right technique for different ages. Cardiac emergencies can happen to anyone, whether infants, children, or adults, and knowing how to respond quickly and correctly can save a life.
CPR differs depending on age. Adults need firm chest compressions about two inches deep. Children require gentler pressure, and infants need just two fingers. Compression-to-breath ratios also vary. Following AHA guidelines ensures safe and effective resuscitation tailored to each age group.
Learning age-specific CPR techniques and practicing regularly can make a real difference in emergencies. Certification and preparation increase your ability to save lives.
Why Does CPR Differ for Adults, Children, and Infants?
CPR differs for adults, children, and infants because their bodies and medical needs are very different. Adults have larger, fully developed bodies that can handle strong compressions, while children and infants need gentler, controlled pressure to avoid injury. Knowing the right technique helps you respond safely and effectively in an emergency, giving the best chance to keep blood and oxygen flowing.
The causes of cardiac arrest also vary by age. Adults often experience heart-related issues, while children and infants usually stop breathing first due to choking, drowning, or illness. This means you must adjust hand placement, compression depth, and breathing technique based on age. Using age-appropriate CPR ensures safe, effective resuscitation without causing harm.

How Can You Perform Adult CPR Effectively in an Emergency?
Adult CPR is performed on anyone aged 12 and older who is unresponsive and not breathing normally. Most adult cardiac arrests are heart-related, so you follow AHA-recommended steps, focusing on strong, effective chest compressions to keep blood flowing to the brain and vital organs. Performing CPR correctly until help arrives can greatly improve survival chances.
According to the AHA guidelines, Adult CPR Steps are as follows:
1. Ensure Scene Safety
Before you approach, quickly check the surroundings to make sure it’s safe for both you and the victim. Remove hazards so you can help without putting yourself at risk.
2. Check Responsiveness
Gently tap the person’s shoulder and shout to see if they respond. Look for movement, sounds, or signs of awareness to decide whether you need to call for help or start CPR immediately.
3. Call for Emergency Help
If the person is unresponsive, call 911 immediately. If someone is nearby, instruct them to call and bring an AED. Quick action from you and others improves the victim’s survival chances.
4. Open Airway and Check Breathing
Tilt the head back and lift the chin using the head-tilt, chin-lift method. Look for normal breathing and check the pulse for no more than 10 seconds before deciding whether you need to begin CPR.
5. Begin Chest Compressions
Kneel beside the victim, place one hand on the lower half of the sternum and the other on top, interlocking your fingers. Position your shoulders above your hands and push hard and fast at the correct depth.
6. Give Rescue Breaths (If Trained)
After 30 compressions, open the airway and give 2 slow breaths, about one second each. Watch the chest rise. If it doesn’t, re-tilt the head and try again before continuing the CPR cycle.
7. Continue CPR Cycles
Repeat cycles of 30 compressions and 2 breaths if trained. If not, continue hands-only compressions. Keep performing these cycles until help or an AED arrives, maintaining a steady rhythm and firm compressions throughout.
How Is CPR Different for Children Compared to Adults?
Child CPR is performed on children ages 1 to 12 who are unresponsive and have no pulse. Because their bodies are smaller and more delicate than adults, you follow AHA-recommended steps using moderate chest compressions and rescue breaths. Performing CPR correctly helps address breathing-related cardiac arrests and greatly increases a child’s chance of survival.
Steps to Perform Child CPR:
1. Ensure Safety First
Before you help, quickly make sure the area is safe so neither you nor the child is at risk. Check for hazards like traffic, fire, or electrical wires before approaching the child.
2. See If the Child is Awake
Gently tap the child’s shoulder and call their name to see if they respond. This lets you know if CPR is necessary or if the child may just be asleep or dazed.
3. Check Breathing and Airway
Tilt the child’s head slightly and lift the chin to open the airway. Look, listen, and feel for normal breathing for no more than 10 seconds.
4. Get Help Immediately
If the child is unresponsive and not breathing, call 911 right away or have someone else do it. Ask them to bring an AED while you start CPR.
5. Begin Compressions on the Chest
Place one or both hands on the center of the child’s chest and push about 2 inches deep. Maintain a steady rhythm to keep blood flowing to vital organs.
6. Give Gentle Rescue Breaths
After compressions, open the airway and give 2 slow breaths, watching for the chest to rise. If you are untrained or uncomfortable giving breaths, continue compressions only.
7. Keep the CPR Going
Continue cycles of compressions and breaths until professional help arrives. Stop only if the child shows signs of life, an AED is ready, or trained responders take over.
What Are the Life-Saving Steps of Infant CPR?
Infant CPR is performed on babies under 1 year who are unresponsive and not breathing normally. Because their chests and airways are delicate, you follow AHA-recommended steps using gentle compressions with two fingers and careful rescue breaths. Performing infant CPR correctly during emergencies like choking or sudden collapse can greatly increase survival and reduce long-term complications.
Steps to Perform Infant CPR:
1. Make Sure the Area is Safe
Before you start, check that the area around the infant is safe for both you and the baby. Remove anything that could cause harm while you help.
2. Check If the Infant Responds
Gently tap the infant’s foot or shoulder and call their name to see if they react. Watching for any movement helps you decide if CPR is needed.
3. Open the Airway and Look for Breathing
Place the infant on their back, tilt the head slightly, and lift the chin. Look and listen for normal breathing or movement for no more than 10 seconds before acting.
4. Call for Help Immediately
If the infant is unresponsive and not breathing normally, call 911 right away. If you need to leave, first perform 5 cycles of CPR, or ask someone nearby to call and bring an AED while you continue helping.
5. Start Chest Compressions
Place the infant on a firm surface and use your index and middle fingers to press on the center of the chest, just below the nipple line. Push about 1.5 inches down at a steady rate of 100-120 compressions per minute, letting the chest fully rise each time.
6. Give Rescue Breaths (If Trained)
After compressions, tilt the infant’s head slightly, lift the chin, and give 2 gentle breaths lasting about 1 second each. Watch for the chest to rise, and if it doesn’t, reposition the head and try again.
7. Keep Repeating CPR Cycles
Continue cycles of compressions and breaths without long pauses. Stop only when professional help or an AED is available, or the infant starts moving, coughing, or breathing normally, while staying calm and focused.
What Are Common CPR Mistakes to Avoid for All Ages?
Avoiding common CPR mistakes is crucial for saving lives across all ages. Proper compression depth, correct hand placement, timely rescue breaths, uninterrupted cycles, calling 911 promptly, and using an AED effectively all improve CPR success and safety.
Here is the detailed explanation of the common CPR mistakes during an emergency:
1. Applying Wrong Pressure
Pressing too hard on infants or too lightly on adults can cause injury or reduce blood circulation. You should always use the correct compression depth for the person’s age.
2. Incorrect Hand Placement
Incorrect hand placement or finger positioning and not letting the chest fully rise can decrease CPR effectiveness. You need to place your hands properly to ensure each compression works.
3. Frequent Interruptions
Stopping compressions too often lowers oxygen flow to the brain and vital organs. You should maintain steady compressions until professional help or an AED is available.
4. Improper Rescue Breaths
Breathing too forcefully or using the wrong ratio can harm the lungs or stomach. You must give gentle, controlled breaths to safely provide oxygen.
5. Hesitating to Call 911
Delaying or forgetting to contact emergency services prevents timely care. You should call 911 immediately to get professional help and access an AED.
6. Ignoring AED or Old Techniques
Not using an AED promptly or relying on outdated CPR methods reduces survival chances. You need to follow current guidelines and use available equipment quickly.
