Asthma Action Plan Template: Green Yellow Red Zones


An asthma action plan is one of the most important documents you can have as someone living with asthma. It takes the guesswork out of what to do when your symptoms change, so you’re not trying to make decisions under pressure when you’re already struggling to breathe.

Key Takeaways

  • An asthma action plan divides your management into green, yellow, and red zones based on symptoms and peak flow readings.
  • Tracking daily symptoms and peak flow against your action plan zones helps you respond appropriately to worsening asthma.
  • Recording rescue inhaler use frequency is a key indicator of whether your controller medication is adequate.
  • A completed action plan with personal best peak flow values gives emergency responders critical information during severe attacks.

The template below is based on the green-yellow-red zone framework recommended by most respiratory health organizations. Use it as a starting point, then work through it with your pulmonologist or asthma nurse to customize it with your personal best peak flow reading, your specific medications, and your doctor’s contact information.

If you haven’t read our guides on tracking your asthma triggers and understanding your peak flow numbers, those are worth reading alongside this template. The action plan is most powerful when you’re tracking your numbers daily and know what your baseline looks like.
