Asthma & Anaphylaxis Emergency in the Home

The factors that cause someone to have an anaphylactic or asthmatic reaction are called ‘allergens’ or ‘triggers’.

For someone with anaphylaxis or asthma, it's critical that trigger substances be removed from the immediate environment to reduce the risk of anaphylaxis or an asthma attack.

In order to ‘trigger proof’ your home, you first need to know what the triggers are.

Triggers vary from person to person. You'll need to know what would cause the individual in question to react adversely. You will need to ask the person if this is new territory for you.

Anaphylaxis Triggers

Anaphylaxis is a life-threatening allergic reaction. You are more likely to experience an anaphylactic attack if you have previously had an allergic reaction to something.

Common allergens include foods such as:

• Milk
• Eggs
• Peanuts
• Tree nuts
• Sesame
• Fish
• Shellfish
• Wheat
• Soy

Venom from Bites and Stings:

• Bee
• Wasp
• Ant bites

Medications:

• Over the counter
• Prescribed
• Herbal/alternative

Asthma Triggers

Asthma is a recurring illness of the airways, which become constricted by tightened muscles and the inside lining of the airways becomes swollen and produces thick, sticky mucus.

Common asthma triggers include:

• Cigarette smoke
• Exercise
• Inhaled allergens (e.g. pollens, moulds, animal dander, and dust mites)
• Environmental factors (e.g. dust, pollution, wood smoke, bush fires)
• Chemicals and strong smells (e.g. perfumes, cleaning products)
• Some foods and food preservatives, flavourings, and colourings (uncommon)
• Colds and flu
• Certain medications
• Emotional factors (e.g. laughter and stress)
• Changes in temperature and weather

So you can act fast in an asthma or anaphylactic emergency in the home, the next step is to know the symptoms.

Anaphylaxis symptoms include:

• Tightness of the throat from swelling
• Difficulty breathing
• Tongue and facial swelling
• Hoarse voice or difficulty speaking
• A wheeze or persistent cough
• Collapse or falling unconscious
• Becoming pale or floppy (young children)
• Abdominal pain and vomiting
• Hives, welts and body redness

The most common asthma symptoms include:

• Wheezing
• Shortness of breath
• Chest tightness
• Coughing fits
• Difficulty breathing
• Dry, irritating, persistent cough, particularly at night and early morning

In the event of a severe asthma attack, you should call 000 immediately.

Symptoms of a severe asthma attack include:

• Gasping for breath, having little or no wheeze due to lack of air movement
• Severe difficulties breathing
• Severe chest tightness
• Only able to speak a few words at a time
• Feeling distressed and anxious
• Blue discolouration on or around the lips (if skin colour also changes this can be hard to see)
• Pale and sweaty skin
• Sucking in of throat and rib muscles
• Using shoulder muscles or bracing with arms to help with breathing
• Symptoms rapidly getting worse or frequently using reliever more than every 2 hours
• Children may become restless, unable to to settle or become drowsy
• Children may also have trouble eating and drinking due to shortness of breath
• A child may have severe coughing or vomiting

No matter how well you trigger proof your home, in sensitive cases, it takes just a small amount of the allergen to set off an attack.

For that reason, make sure you know how to react to an anaphylaxis and asthma emergency in your home.

First Aid for Anaphylaxis

• Lay victim flat, do not stand or walk, or if laying down makes breathing difficult you should allow them to sit
• Prevent further exposure to the triggering agent if possible
• Administer adrenaline through auto-injector such as an Epipen or Anapen
• Call an ambulance (even if they appear to be ‘getting better’)
• Further adrenaline should be given if no response after five minutes
• If breathing stops, commence CPR immediately

First Aid for Asthma

• Without delay give 4 separate puffs of a “reliever,” best given one puff at a time via a spacer device (if a spacer is not available, simply use the puffer).
• Ask the person to take 4 breaths from the spacer after each puff of medication.
• Use the person’s own inhaler if possible. If their own is not available or they don’t have one, use a first aid kit inhaler if available, or borrow one from someone else.
• Wait 4 minutes.
• If there is little or no improvement, give another 4 puffs as above.
• If there is still no improvement after the second round of treatment, call an ambulance immediately.
• Keep giving 4 puffs every 4 minutes until the ambulance arrives.
