Using The Device For The First Time; Inserting The Batteries; Selecting The Correct Cuff; Connecting The Pump Ball - Microlife BP N1 Basic Manual

Range Systolic Diastolic Recommendation
1. blood pressure < 120
normal
2. blood pressure 120 - 129 74 - 79
optimum
3. blood pressure 130 - 134 80 - 84
elevated
135 - 159 85 - 99
4. blood pressure
too high
≥ 160
5. blood pressure
dangerously
high
The higher value is the one that determines the evaluation.
Example: a blood pressure value of 140/80 mmHg or a value of
130/90 mmHg indicates «blood pressure too high».

2. Using the device for the first time

Inserting the batteries

After you have unpacked your device, first insert the batteries. The
battery compartment 6 is at the back of the device. Insert the
batteries 2 x 1.5 V, size AAA), thereby observing the indicated
polarity.

Selecting the correct cuff

Microlife offers different cuff sizes. Select the cuff size to match the
circumference of your upper arms (measured by close fitting in the
centre of the upper arm).
Cuff size for circumference of upper arm
M 22 - 32 cm
M - L 22 - 42 cm
L 32 - 42 cm

Only use Microlife cuffs.

When using an L cuff with this device, be sure to only use it
with the corresponding black deflation valve.

The M size cuff supplied with this device is for upper arm
circumferences 22-32cm.
Contact your local Microlife Service if the enclosed cuff 7 does

not fit.

The pump ball and cuff can be placed on either pin 4 or 5.

3. Taking a blood pressure measurement

Checklist for taking a reliable measurement

1. Avoid activity, eating or smoking immediately before the
measurement.
2. Sit down on a back-supported chair and relax for 5 minutes.
Keep your feet flat on the floor and do not cross your legs.
3. Always measure on the same arm (normally left). It is recom-
mended that doctors perform double arm measurements on a
patients first visit in order to determine which arm to measure in
the future. The arm with the higher blood pressure should be
measured.
4. Remove close-fitting garments from the upper arm. To avoid
constriction, shirt sleeves should not be rolled up - they do not
interfere with the cuff if they are laid flat.
5. Always ensure that the correct cuff size is used (marking on the
cuff).
 Fit the cuff closely, but not too tight.
 Make sure that the cuff is positioned 1-2 cm above the
elbow.
 The artery mark on the cuff (ca.3 cm long bar) must lie over
the artery which runs down the inner side of the arm.
 Support your arm so it is relaxed.
 Ensure that the cuff is at the same height as your heart.
6. Switch on the device and wait until «0» appears in the display
and the arrow « » AN starts to flash.
7. Take the pump ball in your free hand (the arm you are not
measuring from) and pump up the cuff. Watch the pressure indi-
cation in the display and pump approx. 40 mmHg higher than
the expected systolic value (the upper value). If you have not
pumped enough, a flashing arrow « » AN will appear telling
you to pump higher.
8. After pumping, the measurement is taken automatically. Relax,
do not move and do not tense your arm muscles until the
measurement result is displayed. Breathe normally and do not
talk.
