This calculator is for people with asthma. It will help you to tell whether your asthma is in good control or not and the condition of your lungs. You must have a peak flow number to use this calculator. Peak flow is how fast you exhale air after taking a deep breath. This calculator will determine your Green, Yellow and Red Zones, based on your personal best peak flow number. Once you know your personal best peak flow number, you can use this calculator or ask your doctor to help determine the values for your Green, Yellow and Red Zones. Green Zone
Green zone indicates that your asthma is in good control. It means that you currently have no symptoms and you should continue with your regular medication.
Yellow Zone
The Yellow Zone is your caution signal. It means you need to take your quick-relief medicine right away. The Yellow Zone also means your asthma may not be in good control. Ask your doctor if you need to change or increase your daily medications.
Red Zone
The Red Zone is your emergency signal. Take your quick-relief medicine immediately. Then, call your doctor to find out what to do, or go directly to a hospital emergency room. |
