Asthma Exacerbation

Your child has been diagnosed with an asthma exacerbation, commonly called an asthma attack.

We know this can be a stressful time with lots of information from healthcare providers. It can be difficult to absorb everything.

We hope the following pages will be helpful in providing you with the education and resources you need to support your child from home.

What is an Asthma Exacerbation?

Asthma is a common, chronic inflammatory condition of the airways.

Asthma exacerbations are most commonly triggered by viral respiratory infections, such as the common cold, influenza, RSV, or coronavirus.

Other potential triggers include allergens, air pollution, seasonal changes, or inconsistent usage of existing steroid puffers.

Symptoms of an Asthma Exacerbation

The most common symptoms seen with an asthma exacerbation include:

  • cough (usually worse at night or with activity)
  • wheezing (high pitched sound when child breathes out)
  • chest tightness
  • difficulty breathing

Hospital Care

If you have been seen by a medical professional, they may have treated your child with medications. Click below to learn more about these medications.

A. Bronchodilators

Bronchodilators work by relaxing the muscles in the airways, thereby improving symptoms of asthma such as cough, wheeze, chest tightness and shortness of breath. Salbutamol (common brand name: Ventolin, most commonly a blue puffer) is most often used but may be given with another medication called ipratropium bromide (common brand name: Atrovent).

During an asthma exacerbation, bronchodilators are usually given using an MDI (puffer) with a spacer or using a nebulizer with the goal of quickly improving symptoms.

B. Steroids

Steroids act to reduce inflammation. In asthma, steroids reduce inflammation in the airways to help improve symptoms. They typically take a few hours to start to work but last over 24 hours. Therefore, it helps provide longer-lasting relief. Commonly prescribed steroids used for an asthma exacerbation include prednisone and dexamethasone.

Not every child requires steroids to treat an asthma exacerbation. If your child was prescribed this medication, please follow the instructions of the doctor and if you have any questions, speak to your doctor or pharmacist.

C. Oxygen

If your child is having difficulty breathing or low oxygen levels, your medical team may give them supplemental oxygen. Oxygen is usually delivered by face mask or nasal prongs. Generally, if a child requires oxygen, then they may need to be admitted to hospital for further care.

Avoid triggers

Common triggers for asthma include:

  • Environmental irritants such as smoke, pollution, and strong odours
  • Airborne allergens such as pollen, mold, dust mites, and pet dander
  • Respiratory infections such as the common cold and flu
  • Physical activity or exercise
  • Very cold and dry air
  • Emotional stress or anxiety

Getting vaccines for the flu and COVID will reduce illness severity and the severity of asthma attacks.

Quick-relief puffer

Also called "rescue" or "reliever" puffers, they act fast to help open the airways. Generally, it is advised to use for symptoms of cough, wheeze, or shortness of breath.

The most common puffer prescribed is a blue puffer called Ventolin (salbutamol). Please use as directed by your physician.

Controller medications

These are daily medications used to reduce airway inflammation. For example, inhaled corticosteroids such as fluticasone or beclomethasone, or non-steroidal medications like montelukast.

Please use as directed by your physician. Not using these types of medications as directed can lead to more frequent asthma attacks.

Spacer and mask

This device increases the amount of medication that gets to your child's lungs, making the inhalers more effective. Here is a 1-minute clip on how to use the spacer with the inhaler: Steps to Using an Inhaler with a Spacer and Mask

When to seek medical attention

Here are some signs that, if present, should lead you to seek immediate medical attention:

  • fast or laboured breathing (skin or muscles around your child's ribs are pulling in with each breath)
  • cyanosis (blue lips or tongue)
  • lethargic or non-responding child
  • quick-relief medication does not seem to be relieving symptoms

Follow Up

Please follow up with your primary care provider unless instructed otherwise. Of course, if you feel your child needs immediate medical attention, please do not hesitate to call 911 or bring them to your closest emergency department.
