(WA Seasonal Guide Aligned with Australian Resuscitation Council Guidelines)
Western Australia’s outdoor lifestyle, food culture, school environments and workplace diversity mean allergic reactions are more common than many people realise. While mild allergic reactions are uncomfortable, anaphylaxis is different — it is rapid, severe and potentially fatal.
Every school, childcare centre, workplace, sporting club and community venue in Perth should have people trained to respond confidently to anaphylaxis. When a severe allergic reaction occurs, seconds matter.
This guide explains how to recognise anaphylaxis, how to administer adrenaline correctly, and what to do while waiting for emergency services — using principles consistent with Australian emergency response guidelines.
If you live or work in WA, this knowledge could save a life.
What Is Anaphylaxis?
Anaphylaxis is a severe, life-threatening allergic reaction that affects multiple body systems.
It can cause:
- Airway swelling
- Severe breathing difficulty
- Sudden drop in blood pressure
- Collapse
- Cardiac arrest
Without immediate treatment, anaphylaxis can become fatal within minutes.
Common Causes of Anaphylaxis in WA
Triggers vary, but in Western Australia the most common causes include:
Food Allergies
- Peanuts
- Tree nuts
- Eggs
- Dairy
- Shellfish
- Sesame
- Wheat
School settings are high-risk environments for food-triggered reactions.
Insect Stings
- Bees
- Wasps
- Ants (including jumper ants in regional areas)
Outdoor events and bush settings increase risk.
Medications
- Antibiotics
- Pain medications
- Anaesthetic agents
Other Triggers
- Latex
- Exercise-induced reactions (rare but possible)
Anyone can develop anaphylaxis — even if previous reactions were mild.
Signs and Symptoms of Anaphylaxis
Anaphylaxis often develops rapidly, usually within minutes of exposure.
Mild to Moderate Allergic Reaction
- Hives or rash
- Swelling of lips, face, eyes
- Tingling in mouth
- Abdominal pain
- Vomiting
Signs of Anaphylaxis (Medical Emergency)
- Difficulty breathing
- Swelling of tongue
- Swelling or tightness in throat
- Difficulty talking or hoarse voice
- Wheeze or persistent cough
- Dizziness or collapse
- Pale and floppy (especially in children)
Any breathing difficulty combined with allergy symptoms should be treated as anaphylaxis.
Call 000 immediately.
Anaphylaxis First Aid: Step-by-Step Response
Step 1: Lay the Person Flat
- Do NOT allow them to stand or walk.
- Lay flat.
- If breathing is difficult, allow them to sit with legs extended.
- If unconscious, place in recovery position.
Sudden standing can cause cardiac arrest in severe anaphylaxis.
Step 2: Administer Adrenaline Immediately
Use an adrenaline auto-injector (e.g., EpiPen).
How to Use an EpiPen (General Steps)
- Remove safety cap.
- Place against outer mid-thigh (through clothing if needed).
- Push firmly until click is heard.
- Hold in place for several seconds.
- Remove and massage injection site.
Adrenaline is the first-line treatment for anaphylaxis.
Do NOT delay administration.
Step 3: Call 000
Even if symptoms improve after adrenaline, ambulance attendance is required.
Tell the operator:
“Anaphylaxis. Adrenaline given.”
Step 4: Monitor and Reassure
- Stay with the person.
- Monitor airway and breathing.
- Be prepared to administer a second dose if symptoms worsen after 5 minutes.
A second auto-injector may be required.
What If There Is No Adrenaline Available?
If an auto-injector is not available:
- Call 000 immediately.
- Lay the person flat.
- Monitor breathing closely.
- Follow DRSABCD if condition deteriorates.
However, many schools and workplaces in WA now carry general-use adrenaline devices for emergencies.
DRSABCD and Anaphylaxis
If the person becomes unresponsive:
D – Danger: Ensure area is safe
R – Response: Check for response
S – Send for help: Confirm 000 called
A – Airway: Open airway
B – Breathing: Check breathing
C – CPR: Start CPR if not breathing normally
D – Defibrillation: Use AED as soon as available
Severe anaphylaxis can lead to cardiac arrest due to lack of oxygen.
Completing a CPR Course Perth ensures you can respond without hesitation.
Anaphylaxis in Children
Children are at particularly high risk in:
- Schools
- Childcare centres
- Birthday parties
- Sporting events
Signs in children may include:
- Sudden quietness
- Pale appearance
- Vomiting
- Floppiness
- Persistent coughing
Every school staff member should have up-to-date first aid training.
Why Laying Flat Is Critical
One of the most dangerous mistakes in anaphylaxis management is allowing the person to stand or walk.
Sudden standing can cause:
- Rapid drop in blood pressure
- Collapse
- Cardiac arrest
Keep the person flat until ambulance arrives.
Common Mistakes During Anaphylaxis
Avoid:
- Waiting to see if symptoms worsen
- Giving antihistamines instead of adrenaline
- Allowing the person to stand
- Delaying calling 000
- Not monitoring after injection
- Leaving the person alone
Antihistamines do NOT treat life-threatening airway swelling.
Adrenaline is always first-line.
Workplace Anaphylaxis Risks in Perth
Work environments where anaphylaxis may occur:
- Schools and childcare
- Aged care facilities
- Hospitality venues
- Outdoor worksites (insect stings)
- Healthcare settings
- Event venues
Employers have a duty of care to ensure staff are trained and prepared.
Completing First Aid Training Perth reduces liability and increases safety.
Outdoor WA Lifestyle and Allergy Risk
WA residents spend significant time outdoors:
- Beach days
- Bushwalking
- Camping
- Sporting events
- Festivals
Insect stings are a major trigger in regional WA.
Always carry prescribed adrenaline if diagnosed with severe allergies.
What Happens at Hospital?
After adrenaline administration:
- Patients are monitored
- Oxygen may be given
- Additional medication may be administered
- Observation continues for several hours
Some reactions can recur (biphasic reaction), which is why hospital assessment is essential.
Preventing Anaphylaxis
While not all reactions can be prevented, risk can be reduced by:
- Avoiding known allergens
- Reading food labels carefully
- Informing schools and workplaces of allergies
- Carrying adrenaline auto-injectors at all times
- Having an up-to-date Allergy Action Plan
Preparation saves lives.
Why First Aid Courses in Perth Are Essential
Anaphylaxis can escalate within minutes.
Completing First Aid Courses in Perth ensures you:
- Recognise severe allergic reactions early
- Administer adrenaline confidently
- Understand correct positioning
- Follow DRSABCD without hesitation
- Perform CPR if required
- Stay calm in high-pressure emergencies
Training transforms panic into structured response.
CPR and AED Readiness in Severe Allergic Reactions
If oxygen deprivation leads to cardiac arrest, CPR must begin immediately.
Immediate compressions maintain blood flow to the brain.
Access to AEDs in workplaces, schools and public venues significantly improves survival outcomes.
Regular CPR refreshers are critical.
