Peak flows and other information

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 or post 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.
