Checking peak flow

Bring your peak flow meter and your record of daily peak flow readings to your office visits. Ask your provider or nurse to check how you use your peak flow meter. They can help make sure you are doing it right. There are several types of peak flow meters. They look different but do the same thing. The instructions below work for all peak flow meters.

Follow these steps to take your peak flow reading:

Step 1

• Move the marker to 0 or to the lowest number on the scale.

• Stand upright. No slouching. If you can't stand, sit up straight in a chair. Be sure you're in the same position each time.

Step 2

• Remove any gum or food in your mouth.

• Slowly take in a deep breath. Fill your lungs all the way.

• While holding your breath, put the mouthpiece of the meter between your teeth. Close your lips tightly around it, making a tight seal around the mouthpiece. Check that your tongue does not block the hole.

• Blow into the mouthpiece once, as hard and fast as you can (1 to 2 seconds). Your peak flow meter will measure how fast you can blow air out.

• Take the meter out of your mouth.

• Check where the marker has moved to on the numbered scale. Write this number down.

Step 3

• Move the marker back to 0. Repeat the above steps 2 more times.

• Write down the highest of the 3 numbers. This is your peak flow number.
