Peak Flow Test

Peak expiratory flow rate test


A small hand-held device known as a peak flow meter can be used to measure how fast you can blow air out of your lungs in one breath. This is your peak expiratory flow rate (PEFR), and the test is usually called a peak flow test.


You may be given a peak flow meter to take home and a diary to record measurements of your peak flow. Your diary may also have a space to record your symptoms. This will help you recognise when your asthma is getting worse.

Peak flow test is available in all our stores.
