Dear patient,
Your doctor has prescribed the PARI Peak Flow Meter for you for
measuring the strength of your breathing. This brochure contains
detailed information on how you can learn to be more accurate
in estimating the current state of your respiratory tracts and any
changes in them. Your doctor is drawing up an action plan for you
that will help you to react quickly and optimally to changes in your
illness.
What is a peak flow?
The peak flow measures the force or speed of your exhalation.
Your peak flow result is higher when your health is better, and
lower when your respiratory tracts have narrowed. Peak flow val-
ues are also the basis on which asthma is classified into different
degrees of severity.
The aim of this is to achieve the most stable peak flow possible.
This means that the differences between morning and evening
measurement results (that also occur in healthy people) are as
low as possible.
Why are peak flow measurements taken?
Both you and your doctor can already detect small changes in the
state of your lungs through regular peak flow measurements. By
taking medication in good time, you can get your asthma under
control or prevent a serious asthma attack. Your peak flow log
lets you assess whether you are responding to the medication
prescribed for you by your doctor.
Measurement
How is the peak flow measurement carried out?
Measure your peak flow values at least twice a day, and if pos-
sible at the same time each day, e.g. in the morning on getting up
and in the evening before going to bed. If you are breathless or
have a bronchial infection, you should take additional readings.
• Push the pointer to the lower end of the measurement scale.
• Hold the device horizontally in front of your mouth.
Please make sure that your fingers are not covering the pointer
slit or the openings at the end of the device.
• Take a deep breath. Firmly surround the mouthpiece using your
lips and teeth.
• Blow as hard as possible into the peak flow meter using just
one breath.
• Read off the value from the pointer position. Take a note of the
value and push the pointer back to the lower end of the scale.
• Take two more readings and then work out the colour zone of
the highest of the three readings.
• Enter the highest of the three readings (personal best) into the
enclosed log table.
