Question: How Do I Use My Peak Flow Meter?
Answer: It is important to use a peak flow meter correctly if you want to get accurate peak flow readings. Luckily, it is a simple device to learn how to use. Here is a list of the steps:
- Gather your meter, a pencil or pen, and paper or a diary
- Move the slider on the peak flow meter to zero or the lowest point on the scale
- Stand up straight and breathe in deeply
- Wrap your lips tightly around the mouthpiece of the peak flow meter
- Breathe out as fast and forcefully as you can
- Make sure your tongue doesn't block the mouthpiece as you blow out
- Write down the number where the slider is after your exhale
- Repeat the steps above two more times
- Compare the 3 peak flow readings and write the highest one in your peak flow diary
- Compare this number to your personal best PEF rate and consult your asthma action plan to see if you need to take action
