Peak Flow Meter

What is a peak flow meter?
A peak flow meter measures how fast you can
move air out of your lungs in one breath. It is
best to check your peak flows around the
same time each day.

How do you use a peak flow meter?
1. Before beginning the treatment, wash
your hands with soap and warm water,
or use anti-bacterial hand gel, to
reduce the risk of infection.
2. Check the marker on the peak flow
meter. Be sure it is at the bottom at
zero.
3. Hold the meter straight out. Make sure
your fingers do not cover the scale or
the end.
4. Stand up. Take a deep breath in. Place
the mouthpiece of the meter in your
mouth. Close your mouth tightly
around it. Do not place your tongue in
the hole of the mouth piece.
5. Blow out as hard and as fast as you
can (like you are blowing out a
candle). This will cause the marker to
move up the scale.
6. Read the marker on the scale and write
it down.
7. Repeat all of these steps two more
times.
8. After the third time, take the highest
number of the three tries and write it
down. This is your peak flow reading.

When should I use my peak flow
meter?
ξ During a cold
ξ If you have asthma symptoms
ξ Exposure to a trigger (like tobacco
smoke or animals)
ξ When your asthma medicines are
changed
ξ Before using your quick relief
medicine

How do I clean my peak flow meter?
Wipe the mouthpiece off with warm soapy
water, rinse and let it air-dry.
