Difference Between Infant, Child, and Adult CPR: Techniques, Ratios, Depth & Safety Guidelines

What Is CPR? (Quick Recap)

CPR (Cardiopulmonary Resuscitation) is an emergency technique that helps:

• Maintain blood circulation
• Deliver oxygen to vital organs
• Prevent brain damage
• Increase chances of survival

It combines chest compressions and rescue breaths until medical help arrives.

Why CPR Techniques Differ by Age

Infants, children, and adults differ in:

• Chest size & bone strength
• Lung capacity
• Airway structure
• Heart size

Using the wrong technique can:

• Cause rib fractures
• Damage internal organs
• Reduce CPR effectiveness

Age Categories in CPR

Adult CPR: Technique & Guidelines

When to Perform Adult CPR

• Sudden collapse
• No breathing or gasping
• No pulse

Adult CPR Technique

• Hand position: Two hands, centre of chest
• Compression depth: 5-6 cm (2 inches)
• Compression rate: 100-120/min
• Compression to breath ratio: 30:2

Key Points

•  Use full body weight
•  Allow full chest recoil
•  Use AED as soon as available

 Adult CPR Technique

Child CPR: Technique & Guidelines

When to Perform Child CPR

• Child is unresponsive
• No normal breathing

Child CPR Technique

• Hand position: One or two hands (based on size)
• Compression depth: 5 cm (2 inches)
• Compression rate: 100-120/min
• Ratio (single rescuer): 30:2
• Ratio (two rescuers): 15:2

Special Considerations

•  Be gentle yet firm
•  Do not compress too deeply
•  AED paediatric pads preferred

 Child CPR Technique

Infant CPR: Technique & Guidelines

When to Perform Infant CPR

• Infant is unresponsive
• Not breathing normally

Infant CPR Technique

• Hand position: Two fingers (single rescuer)
• Compression depth: 4 cm (1.5 inches)
• Compression rate: 100-120/min
• Ratio (single rescuer): 30:2
• Ratio (two rescuers): 15:2

Critical Infant CPR Rules

•  Never use full hand
•  Support head & neck
•  Gentle rescue breaths

Role of AED in CPR (All Ages)

An Automated External Defibrillator (AED):

• Detects abnormal heart rhythm
• Delivers shock if needed

AED Use by Age:

• Infants & children: Pediatric pads preferred
• Adults: Standard pads

AEDs significantly improve survival rates.

Common CPR Mistakes to Avoid

• Incorrect hand placement
• Too shallow compressions
• Excessive ventilation
• Stopping CPR too early
• Fear of causing injury

Correct CPR saves lives even if ribs crack.

CPR Training: Why Everyone Should Learn

CPR knowledge is vital for:

• Parents & caregivers
• Teachers & school staff
• Office employees
• Security personnel
• Home-care providers

Early CPR can double or triple survival chances.

CPR Equipment Used in Training & Care

• CPR manikins (adult/child/infant)
• AED trainers
• Bag valve masks (Ambu bags)
• Face shields

CPR equipment, basic life support tool

Latest CPR Guidelines (AHA Based)

• Focus on high-quality chest compressions
• Minimize interruptions
• Early AED use
• Compression-first approach (C-A-B)

Conclusion

The difference between infant, child, and adult CPR lies in technique, depth, force, and safety considerations. Applying the correct CPR method based on age can prevent injury and dramatically improve survival outcomes.

Every second matters during cardiac arrest and proper CPR knowledge empowers ordinary people to save extraordinary lives.
