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 appear.
Maintenance
In order to get the best performance, please follow the
instructions below.
Put in a dry place and avoid the sunshine
Avoid intense shaking
and collisions
Using wet cloths to remove dirt
Avoid touching water,
clean it with a dry cloth in case.
Avoid dusty and unstable
temperature environment
Do not attempt to clean the reusable cuff
with water and never immerse the cuff in
water.
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.
