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.
The lists below include the more common triggers that cause anaphylaxis and asthma attacks:
Anaphylaxis:
Food
Milk
Eggs
Peanuts
Tree nuts
Sesame
Fish
Shellfish
Wheat
Soy
Venom from Bites and Stings
Bee
Wasp
Ant stings
Medications
Over the counter
Prescribed
Herbal/alternative
Asthma
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)
Other triggers for asthmatics:
Colds and flu
Certain medications
Emotional factors (e.g. laughter and stress)
Changes in temperature and weather
2. Know the symptoms
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 & facial swelling
Hoarse voice or difficulty speaking
A wheeze or persistent cough
Collapse or falling unconscious
Becoming pale or floppy (young children)
Abdominal pain & vomiting
Hives, welts & 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
Asthma danger signs
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
3. Know how to react
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
If a person's symptoms and signs suggest anaphylaxis you should follow their Anaphylaxis Action Plan or take the following steps:
Lay victim flat, do not stand or walk, if breathing is difficult, allow to sit
Prevent further exposure to the triggering agent if possible
Administer adrenaline through auto-injector:
Child less than 5 years - 0.15 mg intramuscular injection.
Older than 5 years - 0.3mg intramuscular injection
Call an ambulance
Administer oxygen and / or asthma medication for respiratory symptoms.
Further adrenaline should be given if no response after five minutes.
Without delay give 4 separate puffs of a “reliever”. The medication is 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 victim’s own inhaler if possible. If not, use the first aid kit inhaler if available, or borrow one from someone else.
The first aid rescuer should provide assistance with administration of a reliever if required.
Step 3:
Wait 4 minutes. If there is little or no improvement give another 4 puffs.
Step 4:
If there is still no improvement, call an ambulance immediately. Keep giving 4 puffs every 4 minutes until the ambulance arrives.
