nocturnal blood pressure
measurements
with the WatchBP Home N.
Instruction Manual

Microlife WatchBP Home N is the device designed to measure daily and nocturnal blood pressure.
It strictly follows European Society of Hypertension (ESH)1, 2 and American Heart Association (AHA)3
recommendations of 7-day home measurement period with two measuremetns in the morning and two
in the evening. Using the WatchBP Home N device helps you collect accurate diurnal and nocturnal blood
pressure measurements. This gives a good insight in your daily blood pressure pattern and therefore
provides valuable information to your doctor. The WatchBP Home N device has been clinically validated
according to the ESH protocol4.

Take measurements on 7 consecutive days
In «DIAG.» mode, blood pressure measurements
are taken on 7 consecutive days. ESH1and AHA2
recommend to take a 7-day measurement period with
2 measurements in the morning and 2 measurements
in the evening to get an average of at least 12 morning
and evening measurements for reference. The rst-day
measurments shall be excluded from the analysis.
Two sets of measurements per day
ESH guidelines recommend one double measurement
to be taken in the morning between 06:00 - 09:00 and
one in the evening between 18:00 - 21:00. Always take
the measurements before taking your medication,
unless otherwise directed by your doctor.

Evaluation
After measurements have been carried out for a total
of 7 working days, bring the device to your doctor for
evaluation of your home blood pressure.
However, for user’s convience,
WatchBP Home N has an extended
measurement period and allows
morning measurements between
04:00 - 12:00 and evening
measurements between 18:00 -
24:00.
If it is not in the
measuring time period,
the symbol will be
displayed and the
measurements can not
be taken.
When measurements
have been carried out
for the full 7 days, the

for 3 seconds. The device will take one measurement
automatically as baseline to activate the nocturnal
measurements. It will take the rst measurement two
hours later; the second measurement one hour after
the rst measurement; and the third measurement one
hour after the second measurement. The values of 1st,
2nd and 3rd measurement will be averaged. The baseline

Eight steps for taking proper blood pressure
Step 1
Avoid taking measurements directly after eating,
drinking, or smoking. Allow at least one hour between
these activities and measurement of your blood pressure.
1 Hour
Before
* Shorter tube (20 inches) for «USUAL» and «DIAG.» mode.
* Avoid rolling up long sleeves, as this may lead to constriction
of blood ow to the measurement arm.
Step 2
In «USUAL» and «DIAG.» mode
Prepare a chair and table for the
measurement. The chair should have
a vertical back-rest and the table
should allow your upper arm to rest
at the same height as your heart.
Step 3
Remove all clothing constricting the arm to be
measured. Connect the shorter tube to the cuff then
apply the cuff. Make sure the lower edge of the cuff
is exactly 2–3 cm from the inner fold of your arm. The
tube connecting the cuff to the device should be placed
on the inside of the arm. (Additional visual instruction
can be found on the cuff)

EN
16
Step 4
Sit down and relax for at
least ve minutes prior to
the measurement.
Step 5
Sit upright and lean comfortably against the chair’s
backrest. Press the start button, and the device will
start to measure. During the measurement do not
move, cross your legs, or tense your arm muscles.
Breath normally and do not talk.
Step 6
When the measurement is complete, the readings
are stored for future reference by your doctor. If an
error displays after the readings, please repeat the
measurement procedure from step 1 to 5.

Step 7 (in «DIAG.» mode)
In «DIAG.» mode, there is a 60 seconds countdown
before the measurement starts. Two measurements
will be performed subsequently. After the rst
measurement , another 60 seconds countdown starts
before the second measurement. Be relaxed and do
not move during the countdown.
Step 8 (in «DIAG.» mode)
When seven days of measurements have been
collected, the Doctor Symbol will ash on the display.
Do not forget to bring your WatchBP Home N device
with you on your next visit to the doctor. (Note: the
doctor symbol is only displayed for measurements in
«DIAG.» Mode.)

Longer tube (40 inches) for
«NOCTURNAL» mode
In «NOCTURNAL» mode
Change the shorter tube (20 inches) to the
longer tube (40 inches) in «NOCTURNAL» mode;
therefore, the cuff can be securely attached to the
user’s upper arm during sleep. Avoid the tube to
be kinted during sleep.
The user should be lying supine in bed and put the
device on a table by the bed.

Special Function
The atrial brillation indicator for early
detection
The WatchBP Home N is designed to detect atrial brillation
during blood pressure measurements in the «USUAL» Mode,
«DIAG.» Mode and «NOCTURNAL» Mode. When atrial
brillation is detected, the Ab icon displays. The device can
detect atrial brillation with high accuracy (sensitivity of
95% and specicity of 86%)*. If the atrial brillation icon
is displayed frequently, it is highly recommended to perform
a visit to the doctor.

* Atrial brillation which is a major cause of stroke which
can be detected by this device. However, not all risk factors
for stroke, including atrial utter, may be detected by this
device.
* This device may not detect atrial brillation in people with
pacemakers or debrillators. People with pacemakers or
debrillators should therefore not use this device to detect
atrial brillation.
