How to calculate your Personal Best Peak Flow Reading

Your personal best is the most air you can blow into your peak flow meter when your asthma is under control. When your asthma is under control, measure your peak flow reading every day for two weeks. Each day write down the best or highest number you reached. At the end of two weeks circle the highest number. This is your personal best.
