Peak flow recording 

You will be shown how to use a simple device known as a peak flow meter, and make "peak flow" measurements with it every two hours for about a month.

We appreciate that this requires quite a lot of work from you, but it is a very important test which helps us to reach a diagnosis in many cases.

Once you have completed your readings, please email your peak flow readings to us as soon as you can and before your next clinic appointment; so the clinical team has plenty of time to check the results before we next see you.

• Download instructions on how to measure your peak flow readings and send the results to us here: Word or PDF format.
• Download a peak flow diary for writing down all your measurements and other important information here: Word or PDF format.
