1. Age groups and why paediatric CPR differs

Many childhood arrests follow respiratory failure or shock. Compressions alone do not correct a severe oxygen deficit; trained rescuers should combine compressions with breaths.

GroupBLS scope / approach
InfantYounger than 1 year, excluding the newborn at birth. Use infant chest-depth and hand-technique guidance.
ChildFrom 1 year until signs of puberty. Use the prepubertal compression-to-breath ratios.
Signs of pubertyUse adult BLS. Advanced care still follows the appropriate service’s adolescent/paediatric protocol and patient size.
Newborn at birthUses neonatal resuscitation guidance, not this paediatric BLS algorithm.

2. Indications and immediate decisions

  • Unresponsive, not breathing normally/only gasping, and no definite pulse within 10 seconds: start CPR. Healthcare professionals use the brachial pulse in infants and carotid/femoral pulse in children.
  • A pulse is present but breathing is inadequate: support the airway and give 1 breath every 2–3 seconds (20–30/min); reassess the pulse about every 2 minutes.
  • Start CPR for heart rate below 60/min with poor perfusion despite effective oxygenation and ventilation. A pulse does not exclude the need for paediatric compressions in this situation.

3. Contraindications and limits

There is no routine blood-test contraindication to starting CPR for a recognised arrest. A valid applicable treatment-limitation plan, clear irreversible death or a seriously unsafe scene requires the local emergency/ethical process. Paediatric decisions involve senior clinicians and the relevant family/legal framework.

Do not withhold because the child is small, has a disability or may sustain a rib injury. Once circulation and adequate perfusion return, compressions stop and post-arrest care begins. Termination decisions belong to the authorised team, not one abnormal monitor value.

AHA 2025: Ethics and decisions about CPR

4. Nursing care before / at recognition

  • Prepare weight-based equipment: correctly sized mask and bag, suction, airway equipment, paediatric pads/attenuator and a dose aid. Use weight in kilograms; use a length-based estimate if weight is unknown.
  • Check responsiveness; shout for help, activate the code and send another rescuer for an AED. Assess breathing and pulse together within 10 seconds.
  • A lone rescuer with a phone can activate help on speaker while beginning care. If alone and needing to leave an unwitnessed collapse to call/get an AED, give about 2 minutes of CPR first. For a witnessed sudden collapse, retrieve/use the AED promptly according to the single-rescuer algorithm.
  • Use a firm support without delaying compressions. Assign airway, compressor, defibrillator, access/drug and recorder roles; offer supported family presence when feasible under local policy.

5. Nursing care during paediatric CPR

ComponentInfant / prepubertal child
Rate and depth100–120/min; at least one-third the chest’s front-to-back depth: about 4 cm in infants, 5 cm in children.
Infant hands: 2025 updateUse the heel of one hand or two-thumb encircling technique. If unable to encircle the chest, use heel-of-one-hand. Two-finger infant compressions are no longer recommended.
Child handsOne or two hands on the lower half of the sternum, depending on size and ability to achieve depth; allow full recoil.
Without advanced airwayOne rescuer: 30:2. Two or more rescuers for a prepubertal patient: 15:2. Give visible chest rise without excessive inflation.
With advanced airwayContinuous compressions and 1 breath every 2–3 seconds. Confirm and monitor tracheal tube placement with ETCO₂.
Team qualityKeep pauses under 10 seconds; change compressor about every 2 minutes. Record shocks/doses and assess CPR quality; do not wait for a blood result.

Give oxygen during CPR. Attach the AED promptly; use paediatric attenuation/pads when available. If unavailable, use the available AED rather than withhold defibrillation. Keep pads separate; use an anterior-posterior position if needed for space. Clear all contact for shock delivery and immediately resume CPR afterwards.

6. Rhythms, shocks and reversible causes

VF/pulseless VT: give an unsynchronised shock, then CPR for 2 minutes. The teaching algorithm uses 2 J/kg first, 4 J/kg second, then at least 4 J/kg, not exceeding 10 J/kg or the adult maximum dose. The full guideline permits an initial 2–4 J/kg; 2 J/kg simplifies teaching.

PEA/asystole: CPR, oxygenation/ventilation, access and early epinephrine; no shock unless the rhythm changes to VF/pVT. Check for hypoxia, hypovolaemia, acidosis, hypoglycaemia, potassium disturbance, hypothermia, tension pneumothorax, tamponade, toxins and thrombosis.

In shockable arrest, epinephrine follows initial shock attempts (algorithm: during CPR after the second shock); amiodarone or lidocaine follows persistent VF/pVT after the third shock. Do not delay an available shock to obtain a drug or line.

AHA/AAP 2025: Paediatric cardiac arrest algorithm · AHA/AAP 2025: Full Paediatric Advanced Life Support guideline

7. Drugs: weight, concentration and route

MedicinePaediatric IV / IO arrest doseKey check
Epinephrine (adrenaline)0.01 mg/kg using 0.1 mg/mL concentration = 0.1 mL/kg; maximum 1 mg per dose; every 3–5 minutes.Do not confuse 0.1 mg/mL with the 1 mg/mL preparation used for other indications. PEA/asystole: give as soon as possible.
AmiodaroneShock-refractory VF/pVT: 5 mg/kg bolus, first-dose maximum 300 mg. If needed, repeat to a total of 3 doses; maximum 150 mg for each subsequent dose.Not for routine asystole; check total dose and shock sequence.
Lidocaine: alternative1 mg/kg for shock-refractory VF/pVT.An alternative to amiodarone under the resuscitation protocol.
Cause-specific treatmentGlucose for documented hypoglycaemia; electrolyte correction, antidotes or other treatment when indicated.Calcium/bicarbonate are not routine for all paediatric arrests. Atropine is for selected bradycardia mechanisms, not a replacement for CPR in hypoxic collapse.
After ROSCPrescribed fluids, inotrope/vasopressor, sedation/analgesia or antiseizure therapy as required.Use patient-specific infusion calculations and reassess for overload, hypotension and neurological change.

Calculation example: a 10-kg child needs 0.01 × 10 = 0.1 mg epinephrine; with 0.1 mg/mL, volume = 1 mL. A 10-kg child’s first 2-J/kg shock is 20 J. State units aloud.

8. Investigations: no test should delay CPR

StageAssessment / investigationsNursing purpose
Before / at recognitionRapid breathing/pulse/perfusion assessment; review available weight, history, medicines and recent results.Detect respiratory failure/shock and select the correct age/weight pathway. There is no pre-CPR laboratory checklist to complete.
During CPRECG/AED rhythm; ETCO₂ with advanced airway; bedside glucose; blood gas, lactate and electrolytes if rapidly available.Identify reversible problems while the team continues CPR. Interpret trends with ventilation and perfusion.
During CPR, selected casesExisting invasive arterial pressure or expert ultrasound without extra pauses.Support quality/cause assessment. Do not insert monitoring devices at the expense of compressions.
After ROSCContinuous ECG, pulse oximetry, BP/core temperature; blood gas, glucose, electrolytes, lactate, renal function and other cause-directed tests.Guide oxygen, ventilation and perfusion treatment; identify organ dysfunction.
After ROSC, as indicated12-lead ECG/echo for a cardiac cause; chest imaging for airway/lung issues; EEG with altered consciousness or seizures; CT/MRI when clinically indicated.Clarify cause and injury. Unexpected unexplained arrest may require cardiology/genetic evaluation; not every child needs every test.

9. Nursing care after ROSC

  • Reassess airway, breathing, pulse and perfusion; secure lines and airway, arrange paediatric critical care and closely watch for re-arrest.
  • Titrate oxygen using reliable monitoring and the child’s physiology. The full 2025 PALS recommendation gives a usual 94–99% oxyhaemoglobin-saturation range; the AHA checklist uses 94–98% (or the child’s appropriate normal). Follow the team’s prescribed target; avoid hypoxaemia and excessive oxygen.
  • Use blood gas results to guide ventilation; avoid marked hypocapnia/hypercapnia. Maintain systolic and mean arterial BP above the 10th percentile for age using age-appropriate charts and prescribed therapy.
  • Trend lactate and urine output; monitor temperature, glucose, electrolytes and seizures. Follow temperature-control orders and prevent fever.
  • Document neurological observations with sedation context, communicate with family and hand over the timeline, weight, doses, shocks and likely cause. Debrief after the event.

10. Scenario-based MCQs

Choose one best answer before opening the explanation. These are original Nursing Medium practice questions, not official AHA examination items.

QUESTION 01

A 6-month-old is pulseless. Which compression technique reflects the 2025 update?

  1. Two fingers are the only recommended technique
  2. Heel of one hand or two-thumb encircling technique
  3. Abdominal compressions
  4. Fingertip taps without a depth target
Show answer & rationale

Correct answer: B. Heel of one hand or two-thumb encircling technique

Rationale: The 2025 infant recommendation replaced two-finger compressions because adequate depth was often not achieved.

AHA/AAP 2025: Paediatric Basic Life Support

QUESTION 02

A 4-year-old has HR 48/min, weak pulses and poor perfusion despite effective oxygenation and ventilation. What is needed?

  1. Observe because a pulse is present
  2. Give oral fluids
  3. Wait for complete asystole
  4. Begin CPR while the team treats the cause
Show answer & rationale

Correct answer: D. Begin CPR while the team treats the cause

Rationale: Paediatric severe bradycardia with continuing compromise can require compressions before the pulse disappears.

AHA/AAP 2025: Full Paediatric Advanced Life Support guideline

QUESTION 03

Two trained rescuers perform CPR on a prepubertal 7-year-old without an advanced airway. Which ratio is correct?

  1. 15:2
  2. 30:1
  3. 3:1
  4. 5:1
Show answer & rationale

Correct answer: A. 15:2

Rationale: Two-rescuer prepubertal CPR uses 15:2. Adult CPR and single-rescuer paediatric CPR use different rules.

AHA/AAP 2025: Paediatric BLS, two or more rescuers

QUESTION 04

A lone rescuer begins CPR on a child without an advanced airway. What ratio applies?

  1. 15:1
  2. 3:1
  3. 30:2
  4. Continuous compressions with no breaths
Show answer & rationale

Correct answer: C. 30:2

Rationale: For a single rescuer, 30:2 provides a workable balance while help is obtained.

AHA/AAP 2025: Paediatric BLS, single rescuer

QUESTION 05

An infant has a definite pulse of 110/min but inadequate breathing. Which ventilation plan is best?

  1. One breath every 10 seconds
  2. No breaths if the pulse is normal
  3. Chest compressions immediately regardless of perfusion
  4. One breath every 2–3 seconds with reassessment
Show answer & rationale

Correct answer: D. One breath every 2–3 seconds with reassessment

Rationale: A pulse does not correct respiratory failure. Paediatric rescue ventilation is about 20–30 breaths/min.

AHA/AAP 2025: Paediatric BLS, single rescuer

QUESTION 06

A nurse compresses an infant’s chest only 1 cm. Which target is more appropriate?

  1. At least one-third of chest depth, about 4 cm
  2. Exactly 8 cm in every infant
  3. Only enough to move the clothing
  4. Half of chest depth in every patient
Show answer & rationale

Correct answer: A. At least one-third of chest depth, about 4 cm

Rationale: The depth target scales with the chest. The approximate infant reference is 4 cm; inadequate depth reduces effective CPR.

AHA/AAP 2025: Paediatric Basic Life Support

QUESTION 07

A 10-kg child in VF needs the first shock using the teaching algorithm. What energy is appropriate?

  1. 2 J total
  2. 200 J routinely
  3. 20 J
  4. 100 J
Show answer & rationale

Correct answer: C. 20 J

Rationale: The initial algorithm dose is 2 J/kg: 2 × 10 = 20 J.

AHA/AAP 2025: Paediatric cardiac arrest algorithm

QUESTION 08

VF persists in a 10-kg child after the first shock. What is the second algorithm shock dose?

  1. 4 J total
  2. 40 J
  3. 400 J
  4. No second shock is permitted
Show answer & rationale

Correct answer: B. 40 J

Rationale: The second dose is 4 J/kg, so a 10-kg child receives 40 J.

AHA/AAP 2025: Paediatric cardiac arrest algorithm

QUESTION 09

A 10-kg child needs IV/IO arrest epinephrine. The syringe contains 0.1 mg/mL. Which dose and volume are correct?

  1. 0.1 mg = 1 mL
  2. 1 mg = 10 mL
  3. 0.01 mg = 0.1 mL
  4. 10 mg = 100 mL
Show answer & rationale

Correct answer: A. 0.1 mg = 1 mL

Rationale: 0.01 mg/kg × 10 kg = 0.1 mg. At 0.1 mg/mL, this is 1 mL. Verify the actual concentration.

AHA/AAP 2025: Paediatric cardiac arrest algorithm

QUESTION 10

An intubated prepubertal child is receiving continuous compressions. Which breathing plan is appropriate?

  1. One breath every 10 seconds
  2. No breaths until a pulse returns
  3. Pause compressions after every breath
  4. One breath every 2–3 seconds
Show answer & rationale

Correct answer: D. One breath every 2–3 seconds

Rationale: Paediatric advanced-airway CPR uses a higher ventilation rate than adult advanced-airway CPR.

AHA/AAP 2025: Paediatric cardiac arrest algorithm

QUESTION 11

After a child’s ROSC, systolic and mean arterial BP are below the 10th percentile for age. What is the priority?

  1. Accept this because ROSC has occurred
  2. Escalate and titrate prescribed support above the 10th percentile
  3. Use the same fixed adult BP threshold for every age
  4. Stop all monitoring
Show answer & rationale

Correct answer: B. Escalate and titrate prescribed support above the 10th percentile

Rationale: The updated paediatric post-arrest goal is age-dependent. ROSC alone does not guarantee adequate organ perfusion.

AHA/AAP 2025: Full Paediatric Advanced Life Support guideline

QUESTION 12

A lone rescuer has no phone and must leave an unwitnessed paediatric collapse to obtain help and an AED. What does the single-rescuer pathway advise?

  1. Leave immediately before any CPR in every case
  2. Wait 10 minutes before acting
  3. Give about 2 minutes of CPR first, then obtain help/AED
  4. Do not use an AED in children
Show answer & rationale

Correct answer: C. Give about 2 minutes of CPR first, then obtain help/AED

Rationale: For this unwitnessed, alone-without-ready-communication situation, initial CPR precedes leaving. Witnessed sudden collapse has a different AED priority.
