Personal Best Peak Flow Reading Submission
Use the form below to submit your peak flow reading directly to us :
Measuring your peak flow can tell you and your health care provider how well you blow air out of your lungs. If your airways are narrowed and blocked due to asthma, your peak flow values drop.
Use your peak flow meter to measure your peak flow. If you do not have a peak flow meter you can request one.
How to measure your peak flow
- Move the marker to the bottom of the numbered scale.
- Stand up straight.
- Take a deep breath. Fill your lungs all the way.
- Hold your breath while you place the mouthpiece in your mouth, between your teeth. Close your lips around it. DO NOT put your tongue against or inside the hole.
- Blow out as hard and fast as you can in a single blow. Your first burst of air is the most important. So blowing for a longer time will not affect your result.
- Write down the number you get. But, if you coughed or did not do the steps right, do not write down the number. Instead, do the steps over again.
- Move the marker back to the bottom and repeat all these steps 2 more times. The highest of the 3 numbers is your peak flow number. Write it down in your log chart.
- Normal adult peak flow scores range between around 400 and 700 litres. Let us know if your readings are below this.
Personal Best Peak Flow Reading
Take your peak flow each day for 2 to 3 weeks. Your asthma should be under control during this time. To find your personal best, take your peak flow as close to the following times of day as you can:
- Between noon and 2 p.m. each day
- Each time after you take your quick-relief medicine to relieve symptoms
- Any other time your provider tells you to
These times for taking your peak flow are only for finding your personal best.
Write down the number you get for each peak flow reading.
The highest peak flow number you had during the 2 to 3 weeks when your asthma is under comtrol is your personal best. Please submit this score to us.
Once we receive your personal best score, we will send you a personalised Asthma Action Plan. This plan should tell you when to call us for help and when to use medicines if your peak flow drops to a certain level.
Use Your Peak Flow Meter Every Day
Once you know your personal best, make taking your peak flow a habit. Take your peak flow:
- Every morning when you wake up, before you take medicine. Make this part of your daily morning routine.
- When you are having asthma symptoms or an attack.
- After you take medicine for an attack. This can tell you how bad your asthma attack is and if your medicine is working.
- Any other time we tell you to.
Check to see which zone your peak flow number is in, and follow the instructions in your action plan. If you use more than one peak flow meter (such as one at home and another one at school or work), be sure that all of them are the same brand.
