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 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.
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 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.
What are systolic pressure and diastolic pressure?

Systolic

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?
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 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 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.
