CPR techniques are lifesaving, but they are not one-size-fits-all. The way CPR is performed on a child differs from adult CPR due to differences in body size, physiology, and common causes of cardiac arrest.

Understanding these differences—and learning them through proper CPR certification—helps responders provide safe and effective care in emergencies.

Why CPR Techniques Differ by Age

Children are not simply “small adults.” CPR techniques vary because:

  • Children have smaller, more delicate bodies
  • Cardiac arrest in children is often caused by breathing problems
  • Excessive force can cause injury

Age-appropriate CPR improves survival and reduces complications.

Age Definitions in CPR

CPR classifications are based on age:

  • Infant: Under 1 year
  • Child: 1 year to puberty
  • Adult: Puberty and older

This guide focuses on child vs adult CPR.

Key Differences Between Child CPR and Adult CPR

1. Cause of Cardiac Arrest

  • Child CPR: Often due to choking, drowning, or respiratory failure
  • Adult CPR: Commonly caused by heart disease or sudden cardiac arrest

Training through online CPR certification teaches responders how to recognize these differences quickly.

2. Chest Compression Depth

  • Child CPR: About 2 inches (5 cm) or one-third the depth of the chest
  • Adult CPR: At least 2 inches (5–6 cm)

Using the correct depth prevents injury while ensuring effective circulation.

3. Hand Placement and Technique

  • Child CPR: One or two hands, depending on the child’s size
  • Adult CPR: Two hands placed in the center of the chest

Courses such as basic life support certification provide hands-on guidance for correct technique.

4. Compression-to-Breath Ratio

  • Single rescuer (child or adult): 30 compressions to 2 breaths
  • Two rescuers (child): 15 compressions to 2 breaths

Breaths are especially important in child CPR due to respiratory causes.

5. Use of AEDs

  • Child CPR: Pediatric AED pads preferred (adult pads if unavailable)
  • Adult CPR: Standard AED pads

AED use is always safe and recommended when available.

Hands-Only CPR: Child vs Adult

  • Adults: Hands-only CPR is effective and encouraged for untrained bystanders
  • Children: Rescue breaths are strongly recommended when trained

This distinction is critical and emphasized in CPR and first aid certification programs.

Why Proper Training Matters

Performing CPR incorrectly can reduce its effectiveness or cause harm. Formal training ensures:

  • Correct pressure and depth
  • Proper breathing techniques
  • Confidence during emergencies

Learning through CPR online classes allows caregivers, parents, and teachers to stay prepared without scheduling barriers.

Who Should Learn Child CPR?

Child CPR training is especially important for:

  • Parents and caregivers
  • Teachers and school staff
  • Coaches and childcare providers
  • Babysitters and family members

Prepared adults save young lives.
