Why does my blood pressure
fluctuate throughout the day?
1. Individual blood pressure varies multiple
times everyday. 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.
Why do I get a different
blood pressure at home
compared to the hospital?
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.
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.
Is the result the same if
measuring on the right
arm?
It is ok for both arms, but there will
be some different results for different
people. We suggest you measure the
same arm every time.
ABOUT BLOOD PRESSURE
What are systolic pressure and diastolic pressure?

Irregular Heartbeat Detector
CAUTION
An irregular heartbeat is detected when a heartbeat rhythm varies while the unit is
measuring the systolic and diastolic blood pressure. During each measurement, the
monitor records all the pulse intervals and calculate the average; 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%, the irregular
heartbeat symbol appears on the display when the measurement results are appeared.
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.
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.
ABOUT BLOOD PRESSURE
What is the standard blood pressure classification?
The chart on the right is the
standard blood pressure classifi-
cation published by American
Heart Association (AHA).
Please consult a physician if your measuring result falls outside the range.
Please note that only a physician can tell whether your blood pressure value
has reached a dangerous point.
