Learn How to Perform CPR for Adults, Kids, and Infants

Understanding CPR: What You Need to Know {#understanding-cpr}

Cardiopulmonary Resuscitation (CPR) is a life-saving emergency procedure performed when someone’s heart stops beating or they stop breathing normally. According to the American Heart Association (AHA) 2020 Guidelines, proper CPR technique can double or triple a person’s chance of survival during cardiac arrest.

The Science Behind CPR

CPR works by manually pumping blood through the body when the heart cannot do so on its own. Chest compressions create artificial circulation, while rescue breaths provide oxygen to the lungs. This combination keeps vital organs, especially the brain, supplied with oxygenated blood until professional medical help arrives.

Key CPR Statistics You Should Know

Brain damage begins within 4-6 minutes without oxygen
Effective CPR can maintain 25-30% of normal blood flow
Early defibrillation combined with CPR increases survival rates by 50-70%
Every minute counts – survival rates decrease by 7-10% for each minute without CPR

When to Use AED During CPR: Critical Integration Points {#aed-cpr-integration}

The Golden Rule: AED First When Available

One of the most crucial decisions in emergency response is when to integrate an Automated External Defibrillator (AED) into ongoing CPR. The AHA guidelines are clear: when an AED arrives during CPR, use it immediately.

Step-by-Step AED Integration Protocol

Turn on the AED immediately (open lid or press power button)
Expose the chest and apply pads while CPR continues if another rescuer is available
Follow AED prompts – it will tell you when to stop compressions for analysis
If shock advised: ensure no one touches the victim, deliver shock, resume CPR immediately
If no shock advised: resume CPR without delay

Single Rescuer AED Scenario

When you’re alone and an AED becomes available:

Stop compressions only long enough to turn on the AED
Attach pads to bare chest as quickly as possible
Follow prompts (stop compressions only when instructed)
Always restart compression count at “1” after any interruption

Critical Point: Compression Count Reset

Every time compressions are interrupted (for AED analysis, rescue breaths, or switching rescuers), always restart the chest compression count back at 1. This isn’t about tracking total compressions – it’s about maintaining proper rhythm and form for each compression cycle.

Single Rescuer vs Team CPR Scenarios {#rescuer-scenarios}

Single Rescuer Protocol

When you’re the only person available:

Check responsiveness: Tap shoulders, shout “Are you okay?”
Assess breathing: Look for normal breathing (not gasping)
Check pulse: Maximum 10 seconds for adults/children
Call for help: Activate EMS (911) and request AED
Begin CPR: 30 compressions, 2 rescue breaths
Continue cycles: Until EMS arrives or signs of life return

Two-Rescuer Team Protocol

With two rescuers, efficiency improves dramatically:

Rescuer 1: Performs chest compressions
Rescuer 2: Manages airway and rescue breaths
Switch roles every 2 minutes to prevent fatigue
Different compression-to-breath ratios for pediatric patients

Adult CPR Techniques: Proper Form and Execution {#adult-cpr}

Hand Placement and Compression Technique

Proper hand position:

Lower half of breastbone (sternum)
Heel of one hand, second hand interlaced on top
Fingers lifted off chest wall
Arms straight, shoulders directly over hands

Compression specifications:

Depth: At least 2 inches (5 cm), no more than 2.4 inches (6 cm)
Rate: 100-120 compressions per minute
Ratio: 30 compressions to 2 rescue breaths
Recoil: Allow complete chest recoil between compressions

Adult Rescue Breathing Technique

Head tilt-chin lift: Tilt head back, lift chin
Pinch nose: Close nostrils completely
Seal mouth: Cover victim’s mouth with your mouth
Deliver breath: 1 second duration, visible chest rise
Allow exhalation: Let chest fall before second breath

Pediatric CPR: Children and Infants {#pediatric-cpr}

Age Classifications in Pediatric CPR

Infant: Less than 1 year old
Child: 1 year to onset of puberty
Adult: Puberty and older

Child CPR Technique (1 Year to Puberty)

Compression method:

Smaller child: One hand on lower sternum
Larger child: Two hands (same as adult technique)
Depth: Approximately 2 inches (5 cm) or 1/3 of chest depth
Rate: 100-120 compressions per minute

Compression ratios:

Single rescuer: 30:2 (compressions to breaths)
Two rescuers: 15:2 (compressions to breaths)

Infant CPR Technique (Under 1 Year)

Single rescuer technique:

Hand placement: Two fingers (middle and ring) on lower sternum
Depth: Approximately 1.5 inches (4 cm) or 1/3 of chest depth
Allows freedom for airway management and rescue breaths

Two rescuer technique:

2-thumb encircling method: Both thumbs on sternum, fingers wrapped around chest
More effective: Provides stronger, more consistent compressions
Less fatigue: Sustainable for longer periods

Why Different Techniques for Single vs Two Rescuers?

The choice of compression technique depends on rescue dynamics:

Single rescuer needs flexibility to manage both compressions and airway
Two rescuers allow specialization – one focuses entirely on compressions while the other manages airway and breathing
2-thumb encircling provides superior compression quality but requires dedicated compression rescuer

Rescue Breathing: When and How {#rescue-breathing}

Understanding Rescue Breathing Applications

Rescue breathing serves different purposes depending on the victim’s condition:

During CPR (No Pulse Present)

Combined with compressions to maintain circulation and oxygenation
Brief interruptions only – 2 quick breaths then immediately back to compressions
Focus on efficiency – don’t delay compressions for perfect breaths

Rescue Breathing Only (Pulse Present, Not Breathing)

When the heart is beating but breathing has stopped:

Adults:

1 breath every 5-6 seconds
Approximately 10-12 breaths per minute
Check pulse every 2 minutes

Children and Infants:

1 breath every 3-5 seconds
Approximately 12-20 breaths per minute
Check pulse every 2 minutes

Infant Rescue Breathing: Special Considerations

Critical technique points:

Head position: Neutral, avoid over-extension
Mouth seal: Cover both mouth and nose simultaneously
Gentle delivery: Use air from cheeks, not forceful lung capacity
Watch for chest rise: Visible but gentle elevation

Preventing Gastric Inflation

Why big breaths are dangerous:

Air goes into stomach instead of lungs
Causes stomach distension
Risk of vomiting and aspiration
Reduces CPR effectiveness

Prevention techniques:

Give gentle puffs (~1 second each)
Watch for chest rise, not stomach expansion
Let some air escape from cheeks if resistance felt
Reposition airway if chest doesn’t rise – don’t force air

Choking Emergency Response {#choking-response}

When Choking Becomes Cardiac Arrest

A critical distinction exists between conscious choking treatment and choking-related cardiac arrest:

Conscious Choking Victim Becomes Unresponsive

AHA 2020 Guidelines specify:

Start CPR immediately with chest compressions
Do NOT check pulse first – treat as unresponsive choking victim
Each time you open airway for breaths, look for visible object
Remove object only if clearly visible – no blind finger sweeps

Why Attempt Rescue Breaths with Blocked Airway?

Students often ask this logical question. Here’s the rationale:

Airway may be partially blocked – not completely obstructed
Compressions can dislodge objects – changing position or size of obstruction
Some air may pass around object – better than no ventilation attempt
Visual inspection opportunity – check for visible objects to remove
Combined approach most effective – compressions + attempted ventilation

Where Objects Go When They Move Down

Understanding airway anatomy helps explain treatment urgency:

Larynx (Voice Box):

Complete airflow blockage possible
Usually fatal unless quickly cleared
May cause additional swelling

Trachea (Windpipe):

Main airway to both lungs
Total obstruction means no air movement
Victim remains unresponsive

Bronchi (Lung Branches):

Right bronchus more common (straighter, wider)
Blocks one lung, other may function
Severe breathing difficulty but not immediately fatal

Smaller Airways:

Rarely reached by large objects
Can cause lung section collapse
Risk of later infection or pneumonia

Common CPR Mistakes to Avoid {#common-mistakes}

Compression-Related Errors

Inadequate depth:

Compressions too shallow fail to generate blood flow
Use proper hand technique to achieve correct depth naturally
1/3 chest depth rule works across all ages

Incomplete recoil:

Leaning on chest prevents heart refilling
Allow complete chest return between compressions
Maintain compression rate without rushing

Wrong hand placement:

Too high: ineffective compressions, possible injury
Too low: liver damage risk
Proper landmark: lower half of breastbone

Ventilation Mistakes

Over-ventilation:

Reduces CPR effectiveness
Causes gastric inflation
Increases aspiration risk

Prolonged interruptions:

Brain damage accelerates during compression pauses
Keep rescue breath delivery to 1 second each
Resume compressions immediately

AED Integration Errors

Delaying AED use:

Every second counts for defibrillation
Turn on immediately when available
Don’t continue CPR “for a while” before using AED

Forgetting to restart count:

Always begin at “1” after any interruption
Maintains proper rhythm and technique
Prevents confusion during long resuscitation efforts

Emergency Medical Services Integration {#ems-integration}

How EMS Removes Airway Obstructions

When basic CPR and first aid fail to clear airway obstructions, emergency medical services have advanced tools:

Basic Advanced Techniques

Laryngoscope with Magill forceps: Direct visualization and object removal
Suction devices: Clear fluids and small fragments
Advanced airway insertion: Endotracheal tube may push object aside

Last Resort Procedures

Cricothyrotomy: Surgical airway below obstruction
Only when standard methods fail – rare but life-saving
Requires advanced training – paramedics or physicians

Your Role in EMS Preparation

Effective bystander CPR:

Maintains brain viability until advanced care arrives
Provides circulation EMS can build upon
Buys crucial time for equipment setup and assessment

Information gathering:

Note time CPR started
Observe any response to interventions
Document any visible objects or circumstances
Provide clear, factual report to arriving EMS

Pediatric CPR Special Considerations for Healthcare Providers {#healthcare-considerations}

Key Teaching Points for Medical Professionals

Healthcare providers often need refreshers on pediatric-specific techniques that differ from their adult patient experience:

Assessment Differences

Pulse check locations: Brachial artery for infants vs carotid for children
10-second maximum for pulse assessment across all ages
Responsiveness checks same across age groups

AED Considerations

Pediatric pads or dose attenuator for children under 8 years
Standard adult pads acceptable if pediatric unavailable
Immediate use protocol same as adults

Compression Ratio Variations

Single rescuer: 30:2 for all ages
Two rescuer pediatric: 15:2 for children and infants
Two rescuer adult: Continuous compressions with asynchronous ventilation

Real-World Application Tips

Size assessment shortcuts:

Use hand technique to determine compression approach
Smaller child = one hand naturally gives correct depth
Larger child = two hands prevent inadequate compressions

Efficiency focus:

Minimize analysis paralysis about exact measurements
Focus on technique quality over mathematical precision
Good form with appropriate force trumps precise measurements

Frequently Asked Questions {#faq}

Can I hurt someone by doing CPR wrong?

While technique matters, the risk of harm from CPR is minimal compared to the certain harm from doing nothing during cardiac arrest. Rib fractures may occur but heal – brain death from oxygen deprivation is permanent. The key is to start CPR immediately and do your best.

How do I know if CPR is working?

Signs that CPR may be effective include:

Pulse return (check briefly every 2 minutes)
Spontaneous breathing
Color improvement in skin
Eye movement or other responses Continue CPR until EMS arrives unless clear signs of life return.

What if I get tired during CPR?

CPR is physically demanding. If alone, continue as long as possible – even imperfect CPR is better than none. If others are present, switch rescuers every 2 minutes to maintain compression quality. Call for additional help if available.

Should I do mouth-to-mouth during COVID or other infectious disease concerns?

Hands-Only CPR (compressions without rescue breaths) is acceptable for lay rescuers, especially during infectious disease outbreaks. Professional rescuers should use appropriate personal protective equipment. Some oxygenation occurs through passive air exchange during compressions.

How long should I continue CPR?

Continue CPR until:

EMS arrives and takes over
The victim shows obvious signs of life
You become too exhausted to continue
The scene becomes unsafe

Don’t make assumptions about “how long is too long” – continue until professional help determines next steps.

Can I use an adult AED on a child?

Pediatric pads or dose attenuators are preferred for children under 8 years old, but adult AED pads are acceptable if pediatric options aren’t available. The AED will still analyze rhythm and provide appropriate instructions. Never delay AED use waiting for “perfect” equipment.

Conclusion: Every Second Counts in Emergency Response

CPR skills represent one of the most valuable capabilities any person can possess. The techniques outlined in this comprehensive guide reflect current American Heart Association guidelines and best practices developed through decades of research and real-world application.

Key Takeaways for Effective CPR
