An asthma action plan is a form that you fill out with a clinician that details asthma medications, triggers, symptoms, and plans for asthma flares.
An asthma action plan is a clinician-approved guide that covers medications, triggers, symptoms, and ER guidelines for people with asthma. You fill out the form with your clinician and it’s an important way to learn about and manage asthma. Asthma education generally helps reduce hospitalization and emergency department visits. An Asthma action plan can help people manage asthma and decrease missed time from work and school. Parents of children with asthma should share the plan with a kiddo’s school and anyone else who might look after their child.
Ultimately, the goal of an asthma action plan is to help control asthma and prevent flare-ups so that asthma doesn’t interfere with sleep or daily activities.
What is asthma?
First, we’ll start with lung anatomy. Imagine the lungs as upside down trees. The trunk of the tree is the trachea, aka the windpipe, which is the tube that helps guide the air you breathe in. The air goes from your nose into your pharynx then into your larynx then the trachea into the bronchi. The bronchi are the larger branches that go off the tree trunk. Those separate into smaller branches called bronchioles. Eventually, those branches end in little sacs, which you can think of as leaves on this upside down tree, called alveoli that fill up with air and then help the oxygen get to your blood. Lungs also produce mucus to help trap any dust or dirt that you breathe in. Ultimately, you cough up or swallow mucus to get rid of the trapped mucus.
Allergic asthma is the most common type of asthma, that includes inflammation in the airways. The inflammation is caused by immune cells, which are also involved in allergies and hives (which is why clinicians might talk about the triad of asthma, eczema, and allergies, which often occur together). These cells release molecules when someone encounters a specific trigger, such as dust or pollen. These molecules cause the bronchioles (the small branches of the tree) to tighten too much, which can make someone with asthma feel short of breath, experience chest tightness and wheezing. People with asthma also produce increased amounts of mucus in the lungs, which can also make it hard to breathe. All these symptoms can be distressing and interfere with work, school, and sleep. That’s why early diagnosis and an asthma action plan is so important for people living with asthma.
What are asthma triggers?
Knowing your asthma triggers can also help reduce asthma exacerbations. Common triggers include dust mites, cockroaches and rodents, animal fur, mold, pollen, tobacco smoke, cold air, and certain medications, but you should work with your clinician to try to identify what your triggers are.
How is asthma managed?
Since asthma treatment plans often involve multiple medications that are each used differently and may change over time, it can feel pretty complicated to keep straight. This is why asthma action plans can be so helpful. These plans can look a bit different depending on your age, but they usually include a fast-acting inhaler for quick symptom relief and a maintenance (or “controller”) one for prevention — sometimes the same inhaler can be used for both. Some plans may also include allergy medications to prevent asthma triggers.
For many years, a short-acting beta-2 agonist, or SABA, has been used alone as a “rescue” inhaler when asthma symptoms flare. This type of medication is a bronchodilator, which means it helps open up the airways. Today, it’s more common for clinicians to recommend a combination inhaler. These may contain a bronchodilator such as a SABA or a long-acting beta-2 agonist (LABA), along with an inhaled corticosteroid (ICS), which lowers inflammation in the lungs. Only some types can be used for quick relief while others are only used as maintenance treatments. Your asthma plan explains exactly which inhaler is for daily use and which is for quick relief.
There are also newer therapies that may be added if maintenance inhalers alone aren’t enough to control symptoms. These are called biologics and are usually given as shots.
Overall, when determining what medicine to use, clinicians use a step-wise approach to adjust your medicines to your changing symptoms and severity to show it can go up or down. But there is no one plan for everyone and it’s common for plans to change over time.
It’s also essential that you or your child know how to use your inhaler properly. Not all inhalers have the same instructions, so make sure to ask your clinician or pharmacist for guidance on how to use your specific type.
What does an asthma action plan include?
Most asthma action plans are color coded. Here are some examples:
(Source:Allergy and Asthma Network)
(Source: American Lung Association)
(Source:American Academy of Pediatrics)
🟩 The green section discusses how to manage asthma when the person with asthma is doing well.
🟨 The yellow section walks through signs of worsening asthma and how to treat it.
🟥 The red section helps folks make plans for a severe asthma flare up.
Each section will list which medications to take, how much, and how often they should be taken.
What do green/yellow/red symptoms look like?
🟩 The green zone:
The person isn’t coughing or wheezing, they can do all their normal activities, and they aren’t waking up coughing or feeling short of breath.
🟨 The yellow zone:
They can feel short of breath, cough or wheeze more frequently, have trouble doing their normal activities and they might wake up at night coughing or wheezing.
🟥 The red zone includes:
Severe breathing problems, difficulty with activities like walking and talking, and their regular medications aren’t helping.
If someone is in the red, this is serious and a medical emergency, and they should be taken to the hospital.
Some asthma action plans also include a section for your primary care clinician’s contact information in case of emergencies.
⚖️ Health Equity Alert
Children who live in cities have increased rates of asthma symptoms and hospitalizations. Studies have shown that increased pollution also worsens asthma. There are also racial disparities in asthma hospitalizations and visits to the emergency room in Medicaid-enrolled children with asthma. Though asthma action plans are an important start, addressing racial health disparities and pollution will go a long way to keeping kids with asthma healthy.
Everyone with asthma should see their clinician regularly to update their plan. Knowing your asthma triggers and how to handle each zone can help improve asthma control and reduce asthma attacks.
