Infant CPR and Choking First Aid: What Every Parent Needs to Know

Cardiac arrest in infants is almost always preceded by a breathing emergency — not a sudden heart problem. That distinction matters enormously, because it means that breathing emergencies are what most parents will face, and that acting quickly to restore breathing is the single most important thing you can do before emergency services arrive.

The NHS, the American Academy of Pediatrics (AAP), and the Resuscitation Council UK all recommend that parents and caregivers learn infant first aid before their baby arrives. This article explains the techniques clearly and accurately, but reading is not the same as practising. In-person training is covered at the end — please do not skip it.

This article is educational information only. It is NOT a substitute for professional medical advice, diagnosis, or treatment.

In case of emergency, call 911 or your local emergency number.

Why Infants Are Different From Adults

Infant first aid differs from adult first aid in important ways. Babies have smaller airways that block more easily. Their chests are more pliable. The proportions of everything — breath volume, compression depth, the position of the head — are scaled to a newborn's body, not an adult's.

The most critical difference is in the sequence. For adults, the priority is chest compressions (because cardiac arrest is usually the primary event). For infants, the priority is rescue breaths first — because breathing failure typically causes the cardiac arrest, not the other way around. Restarting breathing can save a baby's life even before compressions are needed.

Recognising a Choking Infant

An infant who is choking may cough and splutter — and if they are coughing forcefully, encourage them to keep coughing. A strong cough is the body's most effective mechanism for clearing a blockage, and you should not intervene unless it fails.

The warning signs of a severe blockage requiring intervention are:

• The baby cannot cry or make any sound
• The baby cannot cough effectively — only a weak, silent effort
• The face is turning red, then bluish-purple
• The chest is not rising normally

If any of these are present, act immediately.

The 5-Back-Blow and 5-Chest-Thrust Sequence for Infants Under 1 Year

The Resuscitation Council UK and the NHS specify this technique for babies under 12 months. Do not use abdominal thrusts (the Heimlich manoeuvre) on a baby under one year — their abdominal organs are too vulnerable.

Step 1 — Call for help. If there is another adult present, one person should call 999 immediately while the other begins first aid. If you are alone, begin first aid first, then call 999 as soon as possible.

Step 2 — Position the baby face down on your thigh. Hold the baby face-down along your forearm, supporting the head, which should be lower than the chest. Your thigh provides a firm surface.

Step 3 — Give 5 back blows. Use the heel of your free hand to deliver 5 firm blows between the baby's shoulder blades. Each blow should be separate and deliberate — the aim is to dislodge the object with the force of the impact and the change in air pressure.

Step 4 — Check the mouth. Turn the baby face-up, supporting the head. Look in the mouth. If you can see the object clearly, remove it with a finger. Do not perform a blind finger sweep — you may push the object further in.

Step 5 — Give 5 chest thrusts if the blockage remains. Using two fingers on the centre of the chest, just below the nipple line, give 5 sharp downward pushes. These are firmer and slower than CPR compressions.

Step 6 — Repeat. Alternate 5 back blows with 5 chest thrusts, checking the mouth each time. Continue until the object is dislodged, the baby begins breathing, or emergency services arrive and take over.

Infant CPR: The Full Sequence

CPR is needed when a baby is unresponsive and not breathing normally. Follow these steps, in order.

Check responsiveness. Tap the bottom of the baby's foot gently and call their name. Do not shake a baby.

Call 999. If you are alone, give one minute of CPR before stopping to call. If someone else is present, they call while you begin.

Open the airway. Lay the baby on a firm, flat surface. Place one hand on the forehead and gently tilt the head back to a neutral position — not as far back as you would tilt an adult's head. Use one finger under the chin to lift it slightly. This opens the airway without overstretching the neck.

Look, listen and feel for breathing. For no more than 10 seconds: look for chest movement, listen for breath sounds, feel for air on your cheek. Occasional gasps are not normal breathing.

Give 5 initial rescue breaths. Cover both the baby's mouth and nose with your mouth, creating a seal. Give 5 gentle puffs — gentle enough that you see only the chest rise, nothing more. Each breath should last about one second. Too much air risks damaging the lungs.

Begin chest compressions. Place two fingers on the centre of the baby's chest, one finger-width below the nipple line. Press down to approximately one-third of the chest depth — roughly 4 cm. Aim for a rate of 100 to 120 compressions per minute. A useful way to pace this is the rhythm of the song "Stayin' Alive."

Alternate compressions and breaths. Give 30 compressions followed by 2 rescue breaths. Repeat this cycle without stopping.

Continue until: the baby starts breathing normally, emergency services arrive and take over, or a defibrillator (AED) is available and ready to use — though defibrillation is rarely indicated in infants.

CPR and Choking in Toddlers Over 1 Year

From 12 months, the technique shifts slightly. Abdominal thrusts can now be added: after 5 back blows (performed with the child leaning forward rather than face-down on your arm), give 5 abdominal thrusts — standing behind the child, making a fist just above the navel and pulling sharply inward and upward.

The CPR ratio remains 30 compressions to 2 rescue breaths. The compression depth is still approximately one-third of the chest. From age 1, one hand can be used for compressions rather than two fingers, though this depends on the size of the child.

For children, a slightly greater head tilt is used to open the airway than for infants.

Using a Defibrillator (AED)

Automated external defibrillators (AEDs) are found in many public places — shopping centres, sports halls, transport hubs. In cardiac arrest caused by a shockable rhythm, an AED can be life-saving.

Modern AEDs give clear voice instructions and will tell you not to deliver a shock if one is not indicated. Paediatric pads or a paediatric mode are preferred for children under 8, but if only adult pads are available, use them — the benefit outweighs any risk.

If CPR is already in progress, do not stop for more than 10 seconds to apply the AED.

When to Stop CPR

Continue CPR until:

• The baby or child shows clear signs of life (normal breathing, movement, eye opening)
• Emergency services arrive and take over
• A medical professional tells you to stop
• You are physically unable to continue

Do not stop because you are tired or frightened. Emergency dispatchers can guide you through every step by phone — do not hang up once you have called 999.

The Importance of In-Person Training

Reading a description of CPR is useful background knowledge. It is not a substitute for practice. The physical sensation of the correct compression depth, the rate of back blows, and the feel of rescue breaths are things that need to be experienced on a training manikin.

Where to train in the UK:

• St John Ambulance offers regular baby and child first aid courses across the UK, as well as a free first aid app.
• British Red Cross runs in-person and blended baby first aid courses.
• Many NHS trust antenatal departments offer first aid sessions — ask your midwife.

Where to train in the US:

• The American Red Cross and the American Heart Association both offer infant and child CPR/first aid courses, including online-plus-skills-session formats.

The AAP recommends that both parents and any regular caregivers — including grandparents and childminders — are trained before a baby arrives. A two- to four-hour course can be completed before 36 weeks of pregnancy with time to spare.

Frequently Asked Questions

Can I hurt my baby by doing CPR incorrectly?

Broken ribs are possible with chest compressions, but in a baby who is not breathing, that risk is far outweighed by the certainty of brain damage or death from oxygen deprivation. Do not let the fear of doing it wrong stop you from acting. The Resuscitation Council UK is explicit on this point: attempting CPR is always better than doing nothing.

What if I cannot get a seal over the baby's mouth and nose together?

Some parents find it easier to cover only the baby's mouth and pinch the nose, as with adult CPR. Either technique is acceptable as long as the chest rises visibly with each breath.

Is it safe to give back blows if the baby is not definitely choking?

Back blows are only indicated when a baby is displaying signs of severe airway obstruction (cannot cry, cannot cough effectively, face turning blue). If the baby is coughing, crying, or making sound, encourage continued coughing and do not intervene physically.

Should I practise CPR on my baby to stay current?

No. CPR and first aid should be practised on training manikins only, at accredited first aid courses. Compressing a healthy baby's chest can cause serious injury.

Does CPR always work?

No. Infant survival rates depend on many factors including how quickly CPR begins, the underlying cause, and how quickly emergency services arrive. CPR significantly improves survival odds — studies show that bystander CPR roughly doubles or triples survival from out-of-hospital cardiac arrest. Starting immediately matters more than doing it perfectly.

How often should I refresh my training?

The Resuscitation Council UK and the AAP recommend refreshing first aid skills every 1 to 2 years. Confidence and accuracy drop significantly after this period without practice.

Original Insight: Reading About CPR Is Not Enough

This article provides accurate, detailed instructions. But here's the hard truth: you cannot reliably learn CPR from text or even videos. When a baby is unresponsive and not breathing, panic overrides memory, and muscle memory matters. Studies show that people who read CPR instructions but never practice perform significantly worse in actual emergencies than those who have hands-on training—even months later. You need to practice compressions on a manikin so your hands know the correct depth and speed. You need to feel the airway position so that rescuing breathing becomes automatic, not something you have to consciously puzzle through while adrenaline floods your system. In-person training with the British Red Cross, St John Ambulance, or through your NHS antenatal classes is not optional if you want to be genuinely prepared. Additionally, most parents never use CPR on their baby—which is fortunate. But if you do, the first thing you'll do is call 999 and follow the dispatcher's instructions. The dispatcher will guide you through it. You don't need to remember everything perfectly; you need to know the general sequence and be willing to act. Reading this article makes you more confident, which is good. In-person training makes you competent.

Key Takeaways

• Most cardiac arrests in infants are caused by breathing failure, not a primary heart event — which is why rescue breaths come first in infant CPR.
• For choking infants under 1 year: 5 back blows followed by 5 chest thrusts, never abdominal thrusts; repeat until the airway clears or help arrives.
• Infant CPR sequence: unresponsive baby, open airway, 5 initial rescue breaths, then 30 chest compressions (4 cm depth, 100–120/min) followed by 2 breaths — repeat continuously.
• For toddlers over 1 year, abdominal thrusts are added after back blows; the CPR ratio remains 30 compressions to 2 breaths.
• In-person training with a manikin — through St John Ambulance, British Red Cross, or NHS antenatal classes — is essential and should be completed before 36 weeks of pregnancy.
• Never stop CPR because you are unsure — call 999 and follow dispatcher instructions until professional help arrives.
