How To Prepare For A Peak Flow Test

How should I prepare for a peak flow test?

You don't really have to prepare for a peak flow test. You just have to remember to do it. Since a lot of my asthma patients are teenagers, they've got a lot of other things on their mind. They've got to worry about high school and tests, and what they are going to do Saturday night. So you don't really have to prepare for it. You just have to remember to pick it up, open it up, take a deep breath, and breathe into it. Then look at the numbers and write them down.
