1. Introduction
Your new Microlife Peak Flow Meter is a high quality medical
device that measures your maximum possible exhalation which is
called peak flow (referred to in medical terms as PEF – Peak
Expiratory Flow) and forced expiratory volume (commonly known
as FEV1) in 1-second. Regular monitoring of your peak flow is
extremely useful for controlling diseases of the airways such as
asthma, C.O.P.D., or chronic bronchitis.*
The Microlife monitor is very simple to use, so measurements
can easily be performed at home. The Peak Flow Meter is
designed for people of all ages and is suitable for all ages.
Additionally, it automatically stores 240 readings so you can take
your daily results with you when you visit your doctor for a
checkup.
Read through this instruction manual carefully before using the
device and then keep it in a safe place.
*A higher value usually means air is moving easily through your lungs. When asthma
attacks occur air cannot move easily through your lungs and lower values will be noted.
2. Important Information Concerning Intended Use
2.1 Information about the Measurement and Control of
Peak Flow Values
This device is intended for monitoring PEF (Peak Expiratory
Flow Rate) and FEV1 (Forced Expiratory Volume in one second)
for patient home use. The device is designed for pediatric to
adult patients, and the simple interface makes it easy to use.
When the device is used to monitor lung conditions such as
asthma and chronic obstructive pulmonary disease (COPD), the
user should be under the care of a licensed health care
4
professional. A licensed health care professional’s advice is
required to understand the meaning and importance of the
measurements reported by the device and how to decide on an
appropriate treatment plan that defines when to measure.
A peak flow meter is used to measure a person’s “peak
expiratory flow,” which is the fastest speed a person can blow
air out of the lungs after taking in as big a breath as possible.
“Peak expiratory flow” is a simple measure of airflow that can
tell you how well you are breathing. It tells you how well air is
moving through the airways in your lungs.
Forced Expiratory Volume (FEV1) is a measure of the volume of
air expelled in 1-second.
If you have a breathing condition such as asthma or C.O.P.D.,
your physician (or other licensed health care professional) may
recommend that you use a peak flow meter to watch for
changes in your airflow.
Your physician (or licensed health care professional) will give
you a treatment plan that will tell you what actions to take
when you have a change in airflow. In addition, you should
record your peak flow measures (see sections 5.4, Stored
Readings/Memory) as recommended by your physician (or
other licensed health care professional). Reviewing peak flow
measures can help you and your physician (or licensed health
care professional) check closely on your asthma or C.O.P.D. to
provide the best treatment for you.
The treatment plan given to you by your physician or other
licensed health care professional will tell you what action to
5
take when there are changes in your peak flow number.
No matter what your peak flow measures are, if you have signs
and symptoms such as chest tightness, shortness of breath,
coughing or wheezing you should follow your licensed health
care professional’s advice for contacting him or her.
Instructions for using peak flow meter must be followed
carefully in order to get a correct measure of airflow.
If you are unable to obtain a reading, and your monitor is
working correctly, you should contact your physician
immediately.

5.1. Measuring Procedure
1. Press the ON/OFF button to turn the
monitor on. The last result will
appear on the display (0 if there is
no data). The device will sound two
short beeps and arrows will blink to
indicate it is ready for
measurement.
2. You can perform the measurement
while standing or sitting upright.
For better comparison of your data,
you should always perform the
measurement in a similar position.
3. Hold the monitor with both hands
on the two textured compartments.
4. Inhale completely and hold your
breath for a moment.
5. Cover the mouthpiece tightly with
your lips.
6. Blow into the measuring tube as
hard and as fast as you can.
7. A long beep confirms that the result
is recorded. PEF is displayed for
about 3 seconds followed by FEV1.
Then, the monitor will sound two
short beeps indicating that it is
ready for a new measurement.
14
8. It is recommended to perform three
or more measurements sequentially.
9. After each measurement, the actual
reading is shown followed by the
highest reading of your current
measurement session.
10.Press the ON/OFF button again to
switch the monitor off. Before the
monitor switches off, the highest
value of the current measurement
session and its related memory
position MR XX is displayed.
11.Clean the tube and mouthpiece
after use (see section 8).
Please note:
• The monitor only saves the highest reading from a
measurement session (--measurements taken in one
on/off cycle).
• The date and time must be set for the unit to take a
measurement.
• The device stores up to 240 measured values with date and
time. When the memory is full, the oldest values are
automatically erased. Make sure you visit your doctor
in time to analyze your data.
• Please confirm that date and time settings are always actual.
• The performance of the monitor can be affected by
extremes of temperature and humidity. See technical
specifications section for details.
15
5.2. Information about the Measurement and Control of
Peak Flow Values
• It is necessary to keep regular control of your peak flow
values. Doctors generally recommend taking one
measurement in the morning and one in the evening, every
day, normally before inhaling your prescribed drugs. Carry
out additional measurements whenever you feel unwell or
perceive shortness of breath.
• Your doctor is interested in the highest peak flow value that
you can achieve during a measurement session. Please
repeat the measurements until you feel you have got the
best possible result for the moment. Take care to have
sufficient relaxation between measurements.In case of
worsening results at each successive measurement session
talk to your doctor. It may be a sign of instable asthma.
• Please note that asthma attacks are indicated in
advance by low peak flow values before you feel it!
Please contact your doctor in cases such as these.
Also contact your doctor if you have signs and
symptoms such as chest tightness, shortness of
breath coughing or wheezing.
• Self-measurement is a means for control, and is not
intended for diagnosis or treatment. In any event,
please be sure to discuss your measured values with
your doctor. Your doctor will also explain which
values are normal for you.
• You should never alter the dosages of any medication
without talking to your doctor
16
5.3. Self-Assessment with the Traffic Light Indicator
The colored bars on the left hand edge of the display are a
quick visual reference to show the range of your measured
values. As your peak flow raises or lowers, the arrow on the
display will show the measurement as either within the normal
(green), borderline (yellow) or danger (red) range.
As you use the monitor, it will automatically record your best
value and use it to determine your traffic light zones.
Determining the Area Limits
The traffic light indicator can be used in one of two ways:
• Default traffic light zones
• Customized traffic light zones.
Default Traffic Light Zones:
1. The green zone ranges between your personal best
measurement (MAX) and 80% of that reading.
To determine the yellow/green border zone, multiply the
MAX value by 0.8 [Example: 500 l/min x 0.8 = 400 l/min].
2. The yellow zone ranges between your personal best
measurement (MAX)and 60% of that reading.
To determine the yellow/red border zone, multiply the MAX
value by 0.6. [Example: 500 l/min x 0.6 = 300 l/min].
3. The red zone ranges below 50% of your best reading.
Customized Traffic Light Zones:
The Traffic Light Indicator zones can be customized with a
computer and the Asthma software. This Windows compatible
software is free for download from our website (See section 6).
17
CAUTION: Setting area limits, creating a
treatment plan and modifying your traffic
light zone
settings should only be done under
direction
of a physician (or other licensed
health care practitioner). If you would like to
use this feature,determine your customized
zones with your doctor and record them on
the traffic light card (enclosed).
Note: Once customized zones are
programmed, default traffic light
measurements will no longer be taken.
Traffic Light Indicator Colors
The traffic light arrow will raise or lower
according to the zones set for the monitor
(default or customized).
Green Zone – OK
If your measurement is in the green
•
zone, your condition appears to be under
control. Continue your treatment plan.
Yellow Zone – Caution
• If your measurement is in the yellow
zone, measure more frequently and
follow your treatment plan.
Red Zone – Danger
• If your measurement is in the red zone,
your condition is serious. Act as
discussed with your physician or seek
emergency medical treatment.
18
5.4. Stored Readings/Memory
Multiple readings can be taken during a
session, and the monitor will
automatically store the highest reading
from the session (1 session=1 on–off
cycle). This unit stores 240 readings.
Viewing the stored values
1. Switch the monitor on and press the
memory scroll buttons.
2. By pressing the < button, you can see
the latest value stored in the memory
with date and time. Continue to
depress the button to move quickly
through the memory.
3. The > button works in the opposite
direction.
Memory Capacity Low
When the memory reaches 230 or more
readings, MR XX will blink after the
monitor is switched on to indicate that
the remaining memory capacity is low.
Memory Full
When the memory has stored 240
results, the monitor will beep when
the unit is switched on and MR 240
will blink. From this point, a new
measured value will be stored by
overwriting the oldest value.
