Why does blood pressure fluctuate
throughout day?
Pay attention to:
Is the cuff
fastened
properly?Is the cuff too
tight or too loose?
Is the cuff tied on the
upper-arm without
clothing?
Do you feel anxious?
Taking 2-3 deep breaths
before measuring again
for a better reading.
Advice:
Rest for 5
-
minutes
before taking
another reading
.
Individual blood pressure varies
throughout the day. It is also
affected by the way you
fasten
your
cuff and your measurement
position, so always take your
reading under the same conditions.
If you take medications, your blood
pressure will vary more.
Wait at
least 5 minutes be
tween
measurement
s
.
Why do I get a different
blood pressure at home
compared to the hospital?
Blood pressure varies throughout
the day due to weather, emotion,
exercise etc.
There is also the “white coat” effect,
which means blood pressure
usually increases in clinical settings.
Is the result the same
if
I
measur
e
on
either
arm?
It is fine to use on either arm, but
there will be slightly different results
for you. We suggest you measure
on
the same arm every time.

When ventricles contract and pump
blood out of the heart, the blood
pressure reaches its maximum value in
the cycle, which is called systolic
pressure. When the ventricles relax, the
blood pressure reaches its minimum
value in the cycle, which is called
diastolic pressure.
What is the standard blood pressure classification?
Blood pressure classification
published by World Health
Organization (WHO) and
International Society of Hypertension
(ISH) in the table to the right.

During each measurement, the monitor records all pulse intervals
and calculates the average. If there are two or more pulse
intervals, the difference between each interval and average is
more than the average value of ±25%, or if there are 4 or more
pulse intervals, the difference between each interval and the
average is more than the average value of ±15%, the irregular
heartbeat symbol appears on the LCD.
If the IHB symbol displays on the LCD after your reading, it is
usually NOT a cause for concern. However, if the symbol appears
often, we recommend you seek medical advice.
What are systolic pressure and diastolic pressure?
