Emergency First Aid
First Aid for an Asthma Attack
Quick takeaway: sit the person upright, stay with them, give reliever medication through a spacer if available, call 000 if symptoms are severe or not improving, and keep giving asthma first aid until help arrives.
Asthma attacks can look different from person to person. One person may wheeze loudly. Another may barely make a sound but be working hard to breathe. In first aid, the safest approach is to recognise the signs early, follow the person’s asthma action plan if they have one, and call for emergency help when breathing is not improving.
This guide is written for parents, carers, workplace first aiders, educators, and bystanders who may need to help before paramedics arrive. It is general first aid information and does not replace medical advice or a personal asthma action plan.
Quick Summary
- Asthma first aid is needed when someone has wheeze, cough, chest tightness, shortness of breath, or trouble speaking because of breathing.
- A spacer is preferred where available because it helps deliver reliever medicine more effectively.
- Call 000 immediately for severe symptoms, blue lips, exhaustion, collapse, or if the person is not improving.
- Asthma is common in Australia, so this is a useful first aid skill for homes, schools, sport, and workplaces.

Emergency First Aid for an Asthma Attack
The National Asthma Council Australia asthma first aid guidance is the key Australian reference for what to do when someone is having an asthma attack. The core idea is simple: help the person breathe, get reliever medication in, and call 000 early if the attack is severe or not improving.
Asthma first aid steps
- Sit the person upright and stay calm. Do not leave them alone.
- Give 4 separate puffs of a blue/grey reliever puffer, preferably through a spacer. Shake the puffer, give 1 puff, then ask the person to take 4 breaths through the spacer. Repeat until 4 puffs have been given.
- Wait 4 minutes. If breathing has not returned to normal, give another 4 separate puffs.
- If there is still no improvement, call 000 and say it is an asthma emergency. Keep giving 4 puffs every 4 minutes until emergency help arrives.
When Is Asthma First Aid Needed?
Start asthma first aid when someone with asthma, or suspected asthma, is having breathing difficulty. Do not wait for every symptom to appear. Some attacks are noisy, but a severe attack can also be frighteningly quiet.
- Wheezing or whistling when breathing
- Persistent coughing
- Chest tightness
- Shortness of breath or fast breathing
- Difficulty speaking in full sentences
- Pale, sweaty, anxious, exhausted, or blue around the lips
What Can Trigger an Asthma Attack?
Asthma happens when sensitive airways become inflamed and narrow. Triggers vary, which is why a personal asthma action plan is useful. Common triggers include viral illness, exercise, cold air, smoke, dust, pollen, mould, animals, stress, and workplace irritants.
Some household and environmental triggers are easy to underestimate. The National Asthma Council has a patient fact sheet on gas stoves and asthma in children, and bushfire smoke can also worsen breathing symptoms for people with asthma. During smoky days, people with asthma should follow their action plan and reduce smoke exposure where possible.
Asthma remains common in Australia. The Australian Institute of Health and Welfare’s national asthma indicators report current prevalence at about 11% of the Australian population in 2022, and tracks emergency presentations, hospitalisations, medication use, and asthma action plan uptake.
Using a Reliever Puffer and Spacer
A spacer is a holding chamber that connects to a puffer. It makes it easier for the person to breathe medicine in properly, especially for children or anyone struggling with the timing of “press and breathe”.
If the person has their own asthma action plan, follow it. If they do not, use standard asthma first aid. A blue/grey reliever puffer is commonly used in asthma first aid, and asthma reliever medicine is unlikely to harm someone even if the breathing problem turns out not to be asthma.
When to Call 000
Call 000 immediately if the person is severely short of breath, cannot speak normally, is getting worse quickly, is blue around the lips, becomes drowsy or exhausted, collapses, or you are seriously worried.
If symptoms are mild to moderate, give asthma first aid and reassess after 4 minutes. If breathing has not returned to normal after reliever medication, call 000 and continue asthma first aid until paramedics arrive.
If they become unresponsive
Follow DRSABCD. Check response and breathing, call 000, start CPR if they are not breathing normally, and use an AED if one is available.
Why Asthma First Aid Training Matters
Asthma first aid is easy to read but harder to do calmly the first time someone is frightened and struggling to breathe. Training gives you a chance to practise positioning, spacer technique, reliever dosing steps, calling 000, and handing over to emergency services.
- Parents and carers can practise helping a child with a spacer.
- Educators can prepare for asthma emergencies in childcare, school, and sport settings.
- Workplace first aiders can respond faster when a coworker has sudden breathing difficulty.
- Everyone can learn when to stop waiting and call 000.
Our HLTAID011 Provide First Aid course includes asthma first aid as part of broader emergency response training. For educators and people caring for children, HLTAID012 Provide First Aid in an Education and Care Setting is usually the better fit because it focuses more closely on child and care-setting emergencies.
If you are comparing options, this guide to different types of first aid courses in Australia can help you choose the right level. For a child-specific overview, see our article on asthma in children.
Common Questions
Can I help if the person does not have their own puffer?
Yes. If someone appears to be having an asthma attack and their reliever is not available, asthma first aid guidance allows use of another blue/grey reliever puffer if available. Call 000 if symptoms are severe, not improving, or you are unsure.
Should someone lie down during an asthma attack?
No. Sit them upright in a comfortable position. Lying down can make breathing feel harder.
Is a spacer really necessary?
A spacer is preferred where available because it helps the person take the medicine in more effectively. If there is no spacer, use the puffer according to asthma first aid guidance and call 000 if the person is not improving.
Can asthma first aid be used if it might not be asthma?
Yes. National Asthma Council guidance notes that asthma reliever medicine is unlikely to harm someone even if the main problem is not asthma. If the person is struggling to breathe, call 000.
Final Thoughts
An asthma attack can shift from worrying to life-threatening quickly. The best first aider is not the person with the fanciest equipment. It is the person who recognises breathing trouble, sits the person upright, gives reliever medication correctly, calls 000 at the right time, and keeps going until help arrives.
