The Difference Between Adult, Child & Infant CPR

CPR Training Guide: Essential Techniques for Adults, Children, and Infants

Why CPR Knowledge Saves Lives

Cardiopulmonary resuscitation (CPR) is a life-saving emergency skill everyone should know. When someone experiences cardiac arrest—becoming unconscious, unresponsive, with no breathing or circulation—immediate CPR can mean the difference between life and death.

 

Critical Insight: Each age group requires specific CPR techniques due to differences in anatomy and physiology. Understanding these distinctions is essential for effective life-saving intervention.

⚠️ Before You Begin

Adult CPR should be used for individuals over the age of 8. Always ensure scene safety before approaching the victim.

1

Check Responsiveness

  • Tap the person’s shoulder firmly
  • Shout loudly: “Are you okay?”
  • Call Emergency Medical Services (EMS) immediately if no response (dial 911 or local emergency number)
  • If others are present, direct someone specific to call EMS while you begin CPR
2

Assess Breathing

  • Look for chest movement (rise and fall)
  • Listen carefully for breath sounds
  • Feel for air from nose or mouth
  • Take no more than 10 seconds to check
  • If absent or gasping, begin CPR immediately
3

Position the Victim

  • Place person on their back on a firm, flat surface
  • Ideal surfaces: floor, ground, or sturdy table
  • Remove any pillows from under the head
  • Ensure adequate space to work around the victim
  • Move victim only if necessary for safety
4

Perform Chest Compressions

Hand Placement:

  • Kneel beside the person at chest level
  • Place the heel of one hand on the center of the chest (on the breastbone)
  • Interlock your fingers
  • Place the heel of your second hand on top of the first
  • Keep your arms straight, shoulders directly over hands

Compression Technique:

  • Push hard and fast on the center of the chest
  • Compress at least 2 inches (5 centimeters) deep
  • Deliver 100-120 compressions per minute
  • Allow chest to fully recoil between compressions
  • Minimize interruptions in compressions
  • Count out loud to maintain rhythm
5

Give Rescue Breaths

After 30 compressions:

  • Tilt the head back gently (head-tilt, chin-lift method)
  • Pinch the nose shut with your fingers
  • Create a complete seal over the person’s mouth with yours
  • Give 2 rescue breaths
  • Each breath should last about 1 second
  • Watch for the chest to rise with each breath
  • If chest doesn’t rise, reposition the airway and try again
6

Continue the CPR Cycle

Maintain the rhythm:

  • Alternate 30 chest compressions with 2 rescue breaths
  • Continue without stopping until one of the following occurs:

When to Stop CPR

  • The person begins to breathe independently and shows signs of life
  • An AED (Automated External Defibrillator) arrives and is ready to use
  • Emergency Medical Services (EMS) arrive and take over
  • You are physically unable to continue
  • The scene becomes unsafe

⚠️ Critical Reminders

Quality CPR saves lives: Focus on delivering high-quality chest compressions with minimal interruptions. Push hard, push fast, and allow complete chest recoil. Every second of effective CPR increases the chance of survival.

💡 Pro Tips for Effective Adult CPR

  • Use your body weight rather than just arm strength for compressions
  • Switch rescuers every 2 minutes if possible to maintain compression quality
  • Place an AED as soon as one becomes available
  • Don’t check for a pulse unless you’re a healthcare professional
  • Hands-only CPR (compressions without breaths) is acceptable if you’re untrained or uncomfortable giving breaths

⚠️ Before You Begin

Child CPR should be used for individuals between the ages of 1 and 8 years. Use one or two hands depending on the child’s size. Always ensure scene safety before approaching the child.

1

Check for Responsiveness

  • Tap the child’s shoulder gently but firmly
  • Shout: “Are you okay?”
  • Call Emergency Medical Services (EMS) immediately if the child is not responding (dial 911 or local emergency number)
  • If others are present, direct someone specific to call EMS while you begin CPR
2

Check for Breathing

  • Look for chest movement (rise and fall)
  • Listen carefully for breath sounds
  • Feel for air from nose or mouth
  • Take no more than 10 seconds to check
  • If absent or gasping, CPR needs to be performed immediately
3

Position the Child

  • Place the child on their back on a firm, flat surface
  • Ideal surfaces: floor, ground, or sturdy table
  • Remove any pillows from under the head
  • Ensure adequate space to work around the child
  • Move child only if necessary for safety
4

Begin Chest Compressions

Hand Placement:

  • Kneel beside the child at chest level
  • Use one or two hands depending on the child’s size
  • Place the heel of your hand(s) on the center of the child’s chest (on the breastbone)
  • If using two hands, interlock fingers and place the heel of the second hand on top of the first
  • Keep your arms straight, shoulders directly over hands

Compression Technique:

  • Press down firmly on the center of the chest
  • Compress about 1.5 inches (4 centimeters) deep
  • Deliver 100-120 compressions per minute
  • Use gentler force than adult CPR, but still firm and effective
  • Allow chest to fully recoil between compressions
  • Minimize interruptions in compressions
  • Deliver 30 compressions followed by 2 rescue breaths
5

Give Rescue Breaths

After 30 compressions:

  • Tilt the child’s head back gently (head-tilt, chin-lift method)
  • Pinch the child’s nose shut with your fingers
  • Create a complete seal over the child’s mouth with yours
  • Give 2 gentle rescue breaths (gentler puffs than adult CPR)
  • Each breath should last about 1 second
  • Watch for the chest to rise with each breath
  • Use proper airway management to ensure effective breaths
  • If chest doesn’t rise, reposition the airway and try again
6

Continue CPR

Maintain the rhythm:

  • Alternate 30 chest compressions with 2 rescue breaths
  • Continue without stopping until one of the following occurs:

When to Stop CPR

  • The child begins to breathe independently and shows signs of life
  • An AED (Automated External Defibrillator) arrives and is ready to use
  • Emergency Medical Services (EMS) arrive and take over
  • You are physically unable to continue
  • The scene becomes unsafe

⚠️ Critical Reminders for Child CPR

Gentler but effective: Child CPR requires less force than adult CPR due to smaller body size and more fragile bones. Focus on proper compression depth (1.5 inches), maintain the correct rate (100-120/min), and ensure complete chest recoil. Gentle rescue breaths with proper airway management are essential for effective ventilation.

💡 Pro Tips for Effective Child CPR

  • Adjust hand technique based on child’s size—use one hand for smaller children, two hands for larger children
  • Be mindful of force—compressions should be firm enough to be effective but gentle enough to avoid injury
  • Use pediatric AED pads if available; if not, adult pads can be used
  • Maintain proper airway with gentle head-tilt, chin-lift—avoid hyperextending the neck
  • Give gentler breaths than for adults—just enough to make the chest rise visibly
  • Switch rescuers every 2 minutes if possible to maintain compression quality

⚠️ Before You Begin

Infant CPR should be used for babies under 1 year of age. Use extreme gentleness due to the fragility of infant anatomy. Always ensure scene safety before approaching the infant.

1

Check Responsiveness

  • Tap the infant’s foot gently and watch for a reaction
  • Speak loudly to check for response
  • Call Emergency Medical Services (EMS) immediately if the infant does not respond (dial 911 or local emergency number)
  • Never shake an infant to check responsiveness
  • If others are present, direct someone specific to call EMS while you begin CPR
2

Assess Breathing

  • Look for chest movement (rise and fall)
  • Listen carefully for breath sounds
  • Feel for air from the infant’s nose or mouth
  • Take no more than 10 seconds to check
  • If absent or gasping, start CPR immediately
3

Position the Infant

  • Place infant on their back on a firm, flat surface
  • Ideal surfaces: floor, table, or firm mattress
  • Support the infant’s head and neck carefully
  • Ensure adequate space to work around the infant
  • Remove any blankets or clothing from the chest area
4

Perform Chest Compressions

Finger Placement:

  • Position yourself beside or at the infant’s feet
  • Place two fingers (index and middle) on the center of the infant’s chest
  • Position fingers just below the nipple line on the breastbone
  • Avoid pressing on the bottom tip of the breastbone (xiphoid process)
  • Use only two fingers – never use your whole hand

Compression Technique:

  • Press down firmly but gently on the center of the chest
  • Compress approximately 0.5 inches (1.25 centimeters) deep
  • Deliver 100-120 compressions per minute
  • Allow the chest to fully recoil between compressions
  • Keep your fingers in contact with the chest at all times
  • Minimize interruptions in compressions
  • Count out loud to maintain rhythm
5

Give Rescue Breaths

After 30 compressions:

  • Gently tilt the infant’s head back slightly (neutral position – not too far back)
  • Lift the chin gently with one finger
  • Cover both the infant’s nose and mouth with your mouth, creating a seal
  • Give 2 gentle puffs of air (not full breaths)
  • Each breath should last about 1 second
  • Watch for the chest to rise slightly with each breath
  • Use only enough air to make the chest rise visibly
  • If chest doesn’t rise, reposition the airway and try again
6

Continue the CPR Cycle

Maintain the rhythm:

  • Alternate 30 chest compressions with 2 rescue breaths
  • Continue without stopping until one of the following occurs:

When to Stop CPR

  • The infant begins to breathe independently and shows signs of life
  • An AED (Automated External Defibrillator) arrives and is ready to use (use pediatric pads if available)
  • Emergency Medical Services (EMS) arrive and take over
  • You are physically unable to continue
  • The scene becomes unsafe

⚠️ Critical Reminders for Infant CPR

Gentleness is crucial: Infants are extremely fragile. Use only two fingers for compressions and gentle puffs for breaths. The compression depth is much shallower than for adults or children.

Airway positioning: Do not tilt an infant’s head back too far – this can actually block the airway. Keep the head in a neutral “sniffing” position.

💡 Pro Tips for Effective Infant CPR

  • Use only two fingers – never your whole hand, as this can cause serious injury
  • Give gentle puffs – not full breaths. An infant’s lungs are very small
  • Cover both nose and mouth when giving rescue breaths to create a proper seal
  • Watch for chest rise – this confirms you’re giving effective breaths
  • Avoid excessive force – infant bones are soft and can be easily damaged
  • Keep compressions smooth – use a steady, rhythmic motion

Frequently Asked Questions About CPR

Everything You Need to Know About CPR Techniques for Adults, Children, and Infants

Q What are the main differences in CPR techniques for adults, children, and infants?

CPR techniques vary by age group due to differences in body size, bone structure, and fragility:

  • Adults (8+ years): Use two hands interlocked, compress 2 inches (5 cm) deep
  • Children (1-8 years): Use one or two hands, compress 2 inches deep
  • Infants (under 1 year): Use two fingers only, compress 1.5 inches deep

All age groups use the same 30:2 compression-to-breath ratio and 100-120 compressions per minute rate.

Q How do I know when to start CPR?

Start CPR immediately when a person shows these signs of cardiac arrest:

  • Unconscious and unresponsive to tapping or shouting
  • Not breathing or only gasping
  • No signs of circulation or normal movement

Important: Call Emergency Medical Services (EMS) immediately before starting CPR, or have someone else call while you begin compressions.

Q How do I determine which CPR technique to use based on age?

Use this simple age-based guide to determine the appropriate CPR technique:

Age Group CPR Technique Key Identifier
Under 1 year Infant CPR One handed technique
1-8 years Child CPR One or two hands
8+ years Adult CPR Two hands interlocked

Consider the victim’s body size and physical build as well—a large 7-year-old may require adult CPR technique.

Q Are the CPR compression-to-breath ratios different for adults, children, and infants?

No, the ratio is the same for all age groups.

30:2 30 chest compressions followed by 2 rescue breaths

This universal ratio applies to:

  • Adult CPR (single rescuer)
  • Child CPR (single rescuer)
  • Infant CPR (single rescuer)

Note: Healthcare providers may use a 15:2 ratio for two-rescuer infant and child CPR.

Q Can I perform CPR on an adult the same way I would on a child?

No, you should not use the same technique. While the ratio remains the same, the technique differs significantly:

❌ Adult on Child

Using adult compression depth on a child can cause serious internal injuries, broken ribs, or organ damage.

❌ Child on Adult

Using child compression depth on an adult won’t provide adequate circulation to vital organs.

Always match the CPR technique to the victim’s age and size for maximum effectiveness and safety.

Q How long should I continue performing CPR?

Continue CPR without stopping until one of these situations occurs:

  • 1 Signs of Life: The person begins breathing independently, moving, or showing other signs of consciousness
  • 2 AED Available: An Automated External Defibrillator (AED) arrives and is ready to use
  • 3 EMS Takeover: Emergency Medical Services arrive and take over care
  • 4 Physical Exhaustion: You are too physically exhausted to continue effectively
  • 5 Scene Unsafe: The environment becomes dangerous for you or the victim

Remember: Every minute of CPR increases survival chances. Don’t stop unless absolutely necessary.

Q What should I do if I’m afraid of performing CPR incorrectly?

Any CPR is better than no CPR. Here’s what you need to know:

✓ You Can’t Make It Worse

If someone is in cardiac arrest, they are clinically dead. CPR can only help—even imperfect CPR is better than doing nothing.

Options if you’re uncomfortable:

  • Hands-Only CPR: Perform continuous chest compressions without rescue breaths (still highly effective)
  • 911 Guidance: Emergency dispatchers can guide you through CPR step-by-step over the phone
  • Get Certified: Take a CPR certification course to build confidence and proper technique

Q What is the correct chest compression rate for CPR?

The compression rate is the same for all age groups:

100-120
Compressions Per Minute

Tips to maintain the correct rate:

  • Compress to the beat of “Stayin’ Alive” by the Bee Gees (103 BPM)
  • Or “Baby Shark” for children (110 BPM)
  • Count out loud: “One, two, three…” up to 30
  • Use a metronome app if available

Q Do I need CPR certification to perform CPR in an emergency?

No certification is required to perform CPR in an emergency. Good Samaritan laws protect bystanders who provide emergency assistance.

However, CPR certification is highly recommended because it provides:

📚 Proper Training

Learn correct hand placement, compression depth, and rescue breathing techniques

💪 Confidence

Hands-on practice builds confidence to act quickly in emergencies

🏥 AED Training

Learn how to use an Automated External Defibrillator effectively

✅ Job Requirements

Required for healthcare workers, teachers, coaches, and many other professions

Certification typically lasts 2 years and should be renewed regularly to stay current with guidelines.

Q What is hands-only CPR and when should I use it?

Hands-only CPR involves continuous chest compressions without rescue breaths. It’s a simplified, highly effective technique.

When to use hands-only CPR:

  • You’re untrained or uncomfortable giving rescue breaths
  • The victim is an adult in sudden cardiac arrest
  • You don’t have a barrier device for rescue breaths
  • You want to minimize interruptions in chest compressions
