Key Takeaways
- Choking is a life-threatening emergency that demands fast, confident action from whomever is closest.
- The 5 steps for choking first aid for adults and children over 1 year are: encourage coughing, call 000, deliver up to 5 back blows, deliver up to 5 chest thrusts, and alternate until help arrives or CPR is required.
- Australia does not use the Heimlich manoeuvre — back blows and chest thrusts are the evidence-based national standard endorsed by the Australian Resuscitation Council (ARC).
- If the person becomes blue, limp, or loses consciousness, begin CPR immediately starting with chest compressions.
- Reading about first aid is not a substitute for hands-on training — a nationally accredited course through First Aid Pro gives Melbourne residents the skills and confidence to act decisively when it counts.
When Seconds Count — Why Choking First Aid Knowledge Saves Lives
First aid is the immediate care provided to someone who is injured or suddenly unwell, bridging the gap until professional medical help arrives. Choking first aid is a core skill in the HLTAID011 curriculum because quick recognition and a structured response can be the difference between life and death in an airway emergency.
Choking is a recognised cause of preventable death in Australia, and it can happen anywhere — at home, in a Melbourne café, at a school, or in a workplace. When an airway becomes blocked, the person nearest to the casualty is often their only real chance of survival. That is the fundamental power of first aid: it puts life-saving capability in the hands of prepared, everyday people.
What Actually Happens When Someone is Choking?
The human airway is a precisely engineered passage. When we swallow normally, a small cartilage flap called the epiglottis closes over the trachea, directing food and liquid into the oesophagus. When a foreign object — a piece of food, a small toy, a coin — enters the airway instead, it can lodge in the trachea and partially or completely block airflow to the lungs.
A partial blockage may still allow some air through, which is why a strong cough can sometimes resolve the situation without further intervention. A complete blockage cuts off all airflow entirely. Without oxygen reaching the brain, irreversible damage can begin within four to six minutes. Prompt, structured action is not optional — it is essential.
Who Is Most at Risk of Choking?
Choking can affect anyone, at any age, in any setting. Common causes include:
Food that is too large, too dense, or not chewed adequately — particularly common in older adults Small objects such as coins, buttons, beads, or toy components — a serious hazard for young children Eating too quickly, talking while eating, or being distracted at mealtimes Laughing or sudden movement with food in the mouth Certain medical conditions that affect swallowing
Children under three years are at particularly high risk because their airways can be blocked by anything smaller than a 20-cent coin. For Melbourne parents and carers, first aid training is strongly recommended.
How to Recognise Choking — Signs to Watch For
Sign or Symptom | What It Indicates |
Clutching the throat with one or both hands | Universal choking distress signal |
Inability to speak or very weak voice | Significant airway obstruction |
High-pitched noise or silence when breathing | Partial or complete blockage |
Difficulty breathing or laboured breathing | Reduced airflow to the lungs |
Red face progressing to bluish colour (cyanosis) | Lack of oxygen — act immediately |
Weak, ineffective, or silent cough | Person cannot clear the obstruction alone |
Pale, limp, or unconscious | Critical — begin CPR immediately |
The 5 Steps for Choking First Aid — Australian Guidelines
The following five steps represent the correct choking first aid response for adults and children over 1 year of age. This sequence is consistent with the recommendations of the Australian Resuscitation Council (ARC) and applies equally to adults and children over 1 year.
Encourage coughing
Ask them to cough forcefully to expel the obstruction
Call triple zero (000)
Call immediately if coughing fails or the airway stays blocked
Give up to 5 back blows
Heel of hand between the shoulder blades, head lower than body
Give up to 5 chest thrusts
Heel of hand on the lower half of the breastbone, thrust inward
Alternate and start CPR if needed
Continue until cleared, help arrives, or person loses consciousness
Step 1 — Encourage the Person to Cough as Hard as Possible
If the choking person is conscious and able to cough, encourage them to do so with as much force as they can manage. A strong, forceful cough generates significant pressure within the airway and may be enough to dislodge the obstruction on its own. Keep the person as calm as possible — panic reduces the effectiveness of a cough and makes the situation harder to manage.
Do not interfere with an effective cough. If the person is coughing powerfully, their airway is not completely blocked and they may resolve it themselves. If the cough is weak, silent, or produces no result after a short time, move immediately to Step 2.
Step 2 — Call Triple Zero (000) Without Delay
If coughing does not clear the blockage, or the person cannot cough effectively, call triple zero (000) immediately and request an ambulance. Describe the situation clearly and calmly. If other people are nearby, direct someone else to make the call while you continue delivering first aid — do not stop your efforts to make the call yourself if this can be avoided.
Do not wait to see if the situation improves before calling. First Aid Pro Australia and other emergency health authorities consistently advise that calling 000 early is one of the most critical actions a bystander can take. Even if your first aid is effective, the person will still need medical assessment.
Step 3 — Deliver Up to 5 Firm Back Blows Between the Shoulder Blades
Back blows are a central component of the 5 steps for choking first aid in Australia. Position yourself to one side and slightly behind the choking person. Support their chest with one hand and encourage them to lean well forward so their head is lower than their body — this positioning uses gravity to help direct the object toward the mouth rather than further into the airway.
Using the heel of your hand — the firm, fleshy base of the palm — deliver up to 5 sharp, firm blows between the shoulder blades. Check after each blow to see whether the obstruction has cleared. If it dislodges after 2 blows, stop immediately. The aim is to give up to 5 blows and reassess — not to complete all 5 regardless of outcome.
💡 Technique note: Lean the person well forward before delivering back blows. Use the heel of your hand for firm, targeted force. Check after every blow and stop the moment the obstruction clears.
Step 4 — Deliver Up to 5 Chest Thrusts to the Lower Breastbone
If the airway remains blocked after 5 back blows, move immediately to chest thrusts. Stand behind the choking person and place one hand flat on their upper back for support. Place the heel of your other hand on the lower half of the breastbone — the centre of the chest, just above where the ribs meet at the base of the sternum.
Deliver up to 5 sharp, firm inward thrusts, checking after each one to see whether the blockage has cleared. As with back blows, stop as soon as the obstruction is dislodged.
It is worth noting that Australian first aid guidelines specify chest thrusts directed inward to the lower breastbone. This differs from the abdominal thrusts used in the Heimlich manoeuvre, which is not a recommended technique in Australia. For pregnant women or anyone for whom abdominal techniques would be inappropriate, chest thrusts are always the correct approach.
Step 5 — Alternate Back Blows and Chest Thrusts, Then Begin CPR If Needed
If neither the back blows nor the chest thrusts have cleared the blockage, continue alternating: 5 back blows — check — 5 chest thrusts — check — repeat. Maintain this cycle until the obstruction clears, the person is breathing normally, or emergency services arrive.
If at any point the person becomes blue, limp, or loses consciousness, stop back blows and chest thrusts immediately. Lower them carefully to the ground, call 000 if not already done, and begin CPR. Start with chest compressions — place the heel of one hand on the centre of the chest, place your other hand on top, interlock your fingers, and compress firmly at a rate of 100 to 120 compressions per minute. Continue until the person recovers or paramedics take over.

STEP 4
Give up to 5 chest thrusts — heel of hand on lower half of breastbone, thrust inward
STEP 5
Alternate 5 back blows and 5 chest thrusts — begin CPR if the person loses consciousness
Why Australia Uses Back Blows and Chest Thrusts — Not the Heimlich Manoeuvre
If you have encountered the Heimlich manoeuvre through American films or television, you may be wondering why it is not used here. In Australia, abdominal thrusts are not part of the standard choking first aid response, and for good reason.
Technique | Used In | Method | Australian Guideline |
Heimlich manoeuvre (abdominal thrusts) | USA (historically) | Inward and upward thrust to the abdomen | Not recommended |
Chest thrusts | Australia, UK and others | Inward thrust to the lower half of the breastbone | Recommended |
Back blows | Australia, UK and others | Up to 5 sharp blows between the shoulder blades | Recommended — used in combination with chest thrusts |
The Australian Resuscitation Council (ARC), First Aid Pro and the Royal Life Saving Society of Australia all endorse the combined use of back blows and chest thrusts as the appropriate, evidence-based response to choking in adults and children over 1 year. This approach is also consistent with guidelines from the International Liaison Committee on Resuscitation (ILCOR) and the UK Resuscitation Council.
Back blows create vibration and pressure along the airway to help dislodge a foreign object. Chest thrusts replicate the mechanics of a cough from outside the body, compressing the chest cavity and generating airflow that can expel an obstruction. Together, in alternating cycles, they form a safe, well-evidenced intervention sequence — without the risk of internal injury that can be associated with abdominal thrusts.
Recognising When a Choking Emergency Becomes a CPR Emergency
What to Watch For as the Situation Escalates
If your first aid efforts do not clear the airway, watch closely for signs that the situation is becoming critical: the person going limp, their face or lips turning blue from oxygen deprivation, or them losing consciousness and collapsing. When any of these occur, back blows and chest thrusts must stop. The emergency has progressed to one requiring CPR.
If the person is still conscious but visibly weakening — becoming less responsive, struggling to stay upright, or their cough becoming increasingly faint — continue alternating back blows and chest thrusts while waiting for the ambulance. Do not leave them unattended unless calling 000 makes it absolutely necessary.
How to Deliver CPR After a Choking Emergency
Once the person is unconscious and on the ground, begin CPR without delay. Before attempting rescue breaths, look inside the mouth for any visible object. If you can see it, carefully remove it. Do not perform blind finger sweeps — this risks pushing the obstruction further into the airway.
For CPR in an adult after choking: place the heel of one hand on the centre of the chest at the lower half of the breastbone, place your other hand on top, interlock your fingers, and deliver 30 chest compressions at 100 to 120 per minute. After 30 compressions, gently tilt the head back, lift the chin, and attempt 2 rescue breaths. If the airway is still blocked and the breaths do not go in, return immediately to compressions and check the mouth before each rescue breath attempt. Continue this cycle until the obstruction clears, the person recovers, or paramedics take over.
Why Melbourne Residents Need More Than Just First Aid Information
The Gap Between Understanding First Aid and Being Able to Deliver It
There is a meaningful difference between understanding first aid conceptually and being capable of delivering it under real pressure. In a genuine choking emergency — whether it unfolds in a Melbourne home, a Southbank restaurant, or a CBD workplace — the responding person may be frightened, the only adult present, and required to act within seconds. Without hands-on practice, that gap in capability can be fatal.
Research in emergency health education consistently shows that practical, skills-based training — including manikin practice and realistic scenario rehearsal — significantly improves both performance and confidence when a real emergency occurs.
What Melbourne Residents Learn in a Nationally Accredited First Aid Course
A nationally accredited first aid course delivered through a registered training organisation (RTO) such as First Aid Pro covers:
Recognition of medical emergencies including choking, cardiac arrest, anaphylaxis, and stroke Correct techniques for back blows and chest thrusts for adults, children, and infants Comprehensive CPR training including chest compressions, rescue breathing, and AED use, calling triple zero (000), and communicating with emergency services First aid – reference materials and fact sheets for ongoing use after the course
First Aid Pro delivers in-person and online courses at Melbourne training locations and is registered under the Australian Skills Quality Authority (ASQA) framework. All certifications are nationally recognised, valid wherever you live or work across Australia.
How Hands-On Training Builds the Confidence to Act
Confidence in a first aid emergency is built through practice — not through reading alone. When you train with First Aid Pro in Melbourne, you practise these techniques on real manikins, receive direct feedback from qualified instructors, and work through realistic emergency scenarios designed to prepare you for the unpredictability of a real crisis. That hands-on experience is what closes the gap between knowing what to do and actually doing it — quickly, calmly, and correctly — when a life is on the line.
Test Your Knowledge — Choking First Aid Quick Check
Click each question to reveal its answer.
Q1. What is the first action to take if an adult is choking but still able to cough?
Encourage them to cough as forcefully as possible. A strong, effective cough may be enough to dislodge the obstruction without any further intervention.
Q2. When should you call triple zero (000) in a choking emergency?
As soon as coughing has failed to clear the blockage, or the person is unable to cough effectively. If others are present, direct someone else to call 000 while you continue first aid.
Q3. Where do you deliver back blows, and how?
Between the shoulder blades, using the heel of your hand, with the person leaning well forward so their head is lower than their body. Give up to 5 blows and check after each one.
Q4. Where do you place your hand for chest thrusts?
On the lower half of the breastbone — the centre of the chest — using the heel of one hand, thrusting sharply inward. Give up to 5 chest thrusts and check after each one.
Q5. What do you do if the choking person loses consciousness?
Lower them to the ground, call 000 if not already done, and begin CPR immediately starting with 30 chest compressions. Check the mouth for visible objects before each attempt at rescue breathing.
Q6. Why is the Heimlich manoeuvre not used in Australia?
Australian guidelines from the ARC specify back blows and chest thrusts as the evidence-based standard. Abdominal thrusts are not part of current national first aid protocols.
Q7. How many back blows and chest thrusts do you give before reassessing?
Up to 5 of each — give up to 5 back blows, check, then up to 5 chest thrusts, check, and continue alternating. Stop as soon as the obstruction clears.

Frequently Asked Questions
Should I use the Heimlich manoeuvre in Australia?
No. Abdominal thrusts are not recommended under Australian first aid guidelines. The current national standard, endorsed by the ARC, is a combination of back blows and chest thrusts. If you have previously trained in the Heimlich manoeuvre, updating your skills through an accredited Australian first aid course is strongly recommended.
Are the 5 steps for choking first aid the same for adults and children over 1 year?
The 5-step sequence applies equally to adults and children over 1 year of age. First aid for a baby under 1 year requires different techniques — including the use of 2 fingers rather than the heel of the hand for chest compressions — and is also covered in accredited first aid training.
What should I do if a choking person loses consciousness?
Lower them to the ground and begin CPR immediately. Deliver 30 chest compressions, then check the mouth for any visible obstruction before attempting 2 rescue breaths. Continue alternating compressions and breaths until the person recovers or paramedics take over.
Is choking first aid different for pregnant women?
Chest thrusts remain appropriate and safe for pregnant women. Abdominal thrusts should never be used during pregnancy. A comprehensive first aid course will cover pregnancy-specific variations in technique.
Does a first aid course in Melbourne cover choking emergencies?
Yes. Choking first aid — including back blows, chest thrusts, and post-choking CPR — is a core component of all nationally accredited first aid courses. First Aid Pro’s Melbourne courses include hands-on practice of these techniques so every participant leaves genuinely prepared to respond in a real emergency.
