Peak flow monitoring lets you know how well you're controlling your asthma. It does this by telling you which asthma zone you're in. If needed, you'll be given an action plan that tells you what to do if your asthma gets out of control. Your health care team will explain how your symptoms or peak flow #s can help you know which zone you're in.
GREEN ZONE: UNDER CONTROL. When you're in the green zone, you feel good. Your asthma doesn't get in the way of work, activities, or sleep. You're doing a good job controlling your asthma. Note: If you are not staying in the green zone, discuss your med plan w/your health care provider. (80% - 100% of personal best)

Or you may have warning signs like coughing, wheezing, chest ightness, or shortness of breath. Your asthma may keep you from doing some normal activities. TAKE ACTION RIGHT AWAY!
