Overview
You can use an asthma diary to help track your peak flow readings, your symptoms, and your asthma triggers.
- Record your peak expiratory flow. 
- Measure your peak flow often—every morning and evening if possible—if your doctor recommends it. 
 - It may be helpful to record your peak flow using the same green, yellow, and red zone system used in your asthma action plan. 
 
 - Record your symptoms. 
- If you have an asthma attack, write down what you think triggered it and your symptoms. 
 - Write down what kind of medicine you used for quick relief and how well it worked. 
 - Note if you had to call your doctor or get emergency care. This can help you know your triggers and help your doctor monitor your treatment.
