What belongs in an asthma action plan?
A useful action plan translates the prescribed regimen into specific daily, worsening-asthma, and emergency instructions that the patient or caregiver can recognize and follow.
GINA 2026 recommends plans tailored to age, treatment regimen, reliever type, asthma control, and health literacy. A plan may be printed, digital, or pictorial.
- The patient's usual daily controller treatment and device-specific directions
- The prescribed reliever strategy and exact instructions for worsening symptoms
- Symptoms and, when appropriate, peak-flow values that identify each zone
- When and how to contact the clinical team or obtain urgent and emergency care
- Known triggers, exposure-reduction steps, and exercise instructions
- Current clinician, emergency, and caregiver contact information
Plan architecture
Symptoms lead the plan; peak flow adds context
Current guidance recommends basing action plans on changes in symptoms. Peak flow can also be included when clinically appropriate, especially when a patient may not perceive worsening airflow limitation reliably.
Yellow zone
Worsening asthma
Identifies early symptoms and records the prescribed reliever response, temporary adjustments, reassessment, and contact threshold.
Red zone
Medical alert
Records immediate prescribed treatment and clear instructions for urgent clinician contact, emergency evaluation, or emergency services.
Danger signs override the zone: severe breathing difficulty, inability to walk or speak normally, blue or gray lips, confusion, drowsiness, a silent chest, or rapid deterioration require emergency assessment regardless of a peak-flow reading.
Before sharing the plan
- Confirm medication, strength, device, amount, timing, and maximum use with the prescriber.
- Confirm that yellow- and red-zone instructions match the current reliever strategy.
- Check clinician, caregiver, school, workplace, and emergency contacts.
- Make sure the patient or caregiver can explain when and how to use every section.

Common questions
Asthma action plan FAQ
What is an asthma action plan?
An asthma action plan is a written, digital, or pictorial set of individualized instructions for daily treatment, recognizing worsening asthma, changing treatment as prescribed, contacting the clinical team, and obtaining emergency care.
Who should have a written asthma action plan?
Current GINA and CDC guidance supports an individualized written action plan for every person with asthma. It should be appropriate for the patient's age, treatment regimen, reliever type, asthma control, and health literacy.
Can this builder recommend asthma medications or doses?
No. PulmTools only organizes information entered by the user. Medication names, strengths, devices, doses, timing, oral corticosteroid instructions, and treatment changes must be supplied and reviewed by the prescribing clinician.
Should an asthma action plan use symptoms or peak flow?
Action plans should be based on changes in symptoms. Peak expiratory flow may also be included when the clinician considers it useful, particularly for adults or people who perceive airflow limitation poorly. A peak-flow number must not override severe symptoms.
What information belongs in the green, yellow, and red zones?
The green zone documents stable symptoms and usual treatment. The yellow zone lists signs of worsening asthma and the prescribed response. The red zone identifies medical-alert symptoms, immediate prescribed treatment, and when to obtain emergency help.
Does PulmTools store the information entered into the builder?
No. The plan is assembled locally in the browser and is not uploaded or saved by PulmTools. Printing or saving a PDF may pass the information to the device's print system, browser, or chosen storage location.
How often should an asthma action plan be updated?
Review it with the clinical team whenever treatment changes, after a significant exacerbation, when the personal-best peak flow changes, or when the contacts or instructions are no longer current. It should also be revisited during routine asthma reviews.
