Quick answer
Asthma first aid follows a simple 4-step plan: sit the person upright and stay calm; give 4 puffs of a blue or grey reliever puffer, one puff at a time with 4 breaths after each puff, using a spacer if there is one; wait 4 minutes; if there is no improvement, give 4 more puffs. If they are still not improving, call Triple Zero (000), say it is an asthma emergency, and keep giving 4 puffs every 4 minutes until the ambulance arrives.
Emergency: if breathing is severe, the person cannot speak in full sentences, the lips turn blue, or the reliever is not helping, call Triple Zero (000) immediately and keep giving the reliever.

An asthma attack is when the airways narrow and breathing becomes hard, often with wheezing, a tight chest and a persistent cough. Asthma first aid is easy to remember and works even if you are not sure the person has asthma — giving a reliever puffer will not harm them. This guide explains the 4-step asthma first aid plan, how to use a reliever puffer and spacer, the signs of a severe attack, when to call Triple Zero (000), and how a medical ID helps responders.
What is the 4-step asthma first aid plan?
The 4-step asthma first aid plan (the 4x4 plan) is:
- Sit the person upright and stay calm.
- Give 4 puffs of a blue or grey reliever puffer – one puff at a time, with 4 breaths after each puff, using a spacer if available.
- Wait 4 minutes. If there is no improvement, give 4 more puffs.
- If there is still no improvement, call Triple Zero (000) and say it is an asthma emergency. Keep giving 4 puffs every 4 minutes until the ambulance arrives.
This is the standard asthma first aid plan used across Australia, set by the National Asthma Council and Asthma Australia. It is easy to remember as "4 puffs, wait 4 minutes, 4 puffs" — the 4x4 plan.
Asthma first aid steps: sit upright, 4 puffs, wait 4 minutes
Follow these asthma first aid steps in order. Do not lie the person down.
| Step | What you do |
|---|---|
| 1 | Sit the person upright and stay calm. Reassure them and stay with them. |
| 2 | Give 4 puffs of a blue or grey reliever puffer, one puff at a time. Use a spacer if there is one, and take 4 breaths after each puff. |
| 3 | Wait 4 minutes. If there is no improvement, give 4 more puffs. |
| 4 | If still no improvement, call Triple Zero (000), say "asthma emergency", and keep giving 4 puffs every 4 minutes until the ambulance arrives. |
Keep the person sitting upright and calm while you give 4 puffs of their reliever, one puff at a time.
How to use a reliever puffer and spacer
A reliever puffer (such as a blue or grey inhaler containing salbutamol) opens the airways quickly. A spacer is a plastic chamber that helps more of the medicine reach the lungs. If you are helping someone use an inhaler in an emergency, follow these steps for each puff.
| Step | What you do |
|---|---|
| 1 | Shake the puffer and, if using a spacer, fit the puffer into the open end of the spacer. |
| 2 | Put the mouthpiece in the person's mouth and press once to fire a single puff. |
| 3 | Have them take 4 slow breaths in and out through the spacer. |
| 4 | Repeat for a total of 4 puffs, shaking the puffer and giving one puff at a time. |
You will not harm someone by giving a reliever puffer. If you are not sure whether it is asthma, giving a blue or grey reliever is safe. Do not delay first aid while you look for a diagnosis.
Signs of an asthma attack — and a severe attack
An asthma attack can build up over hours or come on quickly. Any of the severe signs below means you should call Triple Zero (000) while you keep giving the reliever.
| Asthma attack | Severe or life-threatening |
|---|---|
| Wheezing or a persistent cough | Gasping for breath, or unable to speak in full sentences |
| Tight chest | Lips turning blue |
| Shortness of breath | Reliever having little or no effect |
| Difficulty with normal activity | Sudden or rapidly worsening symptoms; drowsiness or collapse |
When to call 000 for asthma
- The person is not improving after the first 4 puffs and the 4-minute wait.
- They are struggling to breathe, cannot speak in full sentences, or their lips are blue.
- The attack is severe or comes on suddenly, or you think it may be their first attack.
- You have no reliever puffer available. Call 000 and keep the person upright and calm.
Asthma or anaphylaxis — when you are not sure
Some people have both asthma and severe allergies, and the early signs can look similar. If a person is known to have both and you cannot tell which is happening — especially after a known allergen — give their adrenaline autoinjector (such as an EpiPen) first, then the asthma reliever, and call Triple Zero (000). See our guide to anaphylaxis first aid for the full steps.
Asthma action plans and longer-term management
Beyond first aid, most people with asthma have a written Asthma Action Plan prepared with their doctor. It sets out their usual reliever and preventer medicines, their triggers, and what to do as symptoms change. An action plan is not first aid for a sudden attack — the 4-step plan above is — but it helps prevent attacks and guides day-to-day management. Asthma Australia and the National Asthma Council provide action plan templates, and a GP or pharmacist can help set one up.
Asthma and medical IDs
During a severe attack a person may be unable to speak or explain their condition. A medical ID tells a first responder that the person has asthma and may carry a reliever — information that matters most when they cannot speak. A medical ID can also carry a membership number for an online medical records service such as MedibandPlus.
A medical ID lets a responder know about asthma when the person is too breathless to speak.
With MedibandPlus, that membership number lets first responders access a secure profile that stores the wearer's condition, medications and next-of-kin contact. It does not assess or diagnose anything — it simply makes the wearer's own information available when they cannot speak, so the right care reaches them sooner.
