ABOUT BLOOD PRESSURE
ABOUT BLOOD PRESSURE
Why does my blood pressure
fluctuate throughout the
day?
Is the result the same
if measuring on the
right arm?
Why do I get a different
blood pressure at home
compared to the hospital?
1. Individual blood pressure varies
multiple times throughout the day. It is
also affected by the way you tie your
cuff and your measurement position, so
please take the measurement under the
same conditions.
2.If the person takes medicine, the
pressure will vary more.
3.Wait at least 3 minutes for another
measurement.
The blood pressure is different even
throughout the day due to weather,
emotion, exercise etc... Also, there is
the “white coat” effect, which means
blood pressure usually increases in
clinical settings.
It is ok for both arms, but there
will be some different results for
different people. We suggest you
measure using the same arm every
time.
What you need to pay
attention to when you measure
your blood pressure at home:
If the cuff is tied properly.
If the cuff is too tight or too loose.
If the cuff is tied on the upper arm.
If you feel anxious.
Taking 2-3 deep breaths before
beginning will be better for measuring.
Advice: Relax yourself for 4-5
minutes until you calm down.
Only a physician can tell your normal BP range.
Please contact a physician if your measuring
result falls out of the range. Please note that only
a physician can tell whether your blood pressure
value has reached a dangerous point.
What are systolic pressure and diastolic pressure?
press
artery
vein
blood discharging
Systolic
relax
blood entering
Diastolic
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?
The blood pressure classification published by
World Health Organization (WHO) and
International Society of Hypertension (ISH) in
1999 is as follows:
Irregular Heartbeat Detector
CAUTION
The appearance of the IHB icon indicates that a pulse irregularity consistent with an irregular
heart-beat was detected during measurement. Usually this is NOT a cause for concern.
However, if the symbol appears often, we recommend you seek medical advice. Please note
that the device does not replace a cardiac examination, but serves to detect pulse irregularities
at an early stage.

An irregular heartbeat is detected when a heartbeat rhythm varies while the device is
measuring systolic pressure and diastolic pressure. During each measurement, blood
pressure monitor will keep a record of all the pulse intervals and calculate the average
value of them. If there are two or more pulse intervals, the difference between each
interval and the average is more than the average value of ±25%, or there are four or
more pulse intervals, the difference between each interval and the average is more
than the average value of ±15%, then the irregular heartbeat symbol will appear on the
display with the measurement result.
