1-1. What is blood pressure ?
1. About Blood Pressure
Having one's blood pressure measured by a doctor in a hospital or a clinic, and a
group health checks, tends to stimulate nervousness in the subject and may even
create high blood pressure, blood pressure also varies in accordance with a variety of
conditions and so judgment is not possible on the basis of a single measurement.
The blood pressure measured first thing in the morning after getting up, before taking
any food and with the subject still, is known as the fundamental blood pressure. In
practice it is rather difficult to record the fundamental blood pressure, but to come as
near as possible to measuring the blood pressure in an environment that is close to
this is why it is useful to take the measurement at home.
Blood pressure is a measurement of the force of blood flowing against the walls of
the arteries. Arterial blood pressure is constantly changing during the course of the
cardiac cycle. The highest pressure in the cycle is called the systolic blood pressure
and the lowest is the diastolic blood pressure. Both of pressure readings, the systolic
and the diastolic, are necessary to enable a physician to evaluate the status of a
patient's blood pressure. Many factors such as physical activity, anxiety or the time of
day can influence your blood pressure. Blood pressure is typically low in the morning
and increases from the afternoon to the evening. It is lower in the summer and higher
in the winter.
1-2. Why is it useful to measure blood pressure at home?
A. WHO blood pressure classications
Standards for assessment of high or low
blood pressure without regard to age, have
been established by the World Health
Organization (WHO), as shown in the chart.
High normal
Mild hypertension
Moderate hypertension
Severe hypertension
120 130
140 150 160 170 180
* Figure No.1
B. Variations in blood pressure
* Figure No.2
Individual blood pressures vary greatly
both on a daily and a seasonal basis.
These variations are even more pronounced in hypertense patients.
(Hypertense: means a person who has high blood pressure symptom.)
Normally the blood pressure rises while at work
and is at its lowest during sleeping period. The
graph below illustrated the variations in blood
pressure over a whole day with measurement
taken every five minutes. (The thick line
represents sleep. The rise in blood pressure at 4
PM <A in the graph> and 12 PM <B in the
graph> correspond to an attack of pain.)
Please rest for at least 5 ~ 10 minutes before taking the measurement.
To allow your blood vessels to return to the condition prior to taking the measurement,
please wait at least 3 ~ 5 minutes between measurements. You may need to adjust the
wait time according to your personal physiological situation.
If you have one of the circulatory problems as arteriosclerosis, diabetes, liver disease,
kidney disease, severe hypertension, peripheral circulation......, please consult your doctor
or healthcare professional before using the devices.
Blood pressure measurements should be interpreted by a physician or trained health
professional who is familiar with one's medical history. By using the unit regularly and
recording the results for the physician to interpret, one can keep physician informed of the
continuing trends in one's blood pressure.
Wind the cuff snugly around your wrist and the cuff must be at the same level as your heart.
Do not move the unit during measurement, or the proper measurement will not be achieved.
Take measurement in a relaxed position without talking.
Do not wind the cuff over jacket or sweater sleeve, or measurement cannot be done.
Keep in mind that blood pressure naturally varies from time to time throughout the day and
also is affected by lots of different factors such as smoking, alcohol consumption, medication
and physical activity.
2. Important information before use of the unit
People with a condition that causes circulatory problems (diabetes, kidney disease,
arteriosclerosis or poor peripheral circulation) may get lower readings with this
monitor than with a blood pressure monitor that is used on the upper arm.
Please consult your physician to determine if your wrist blood pressure
accurately reflects your actual blood pressure.
Blood pressure measurements taken with the unit are
equivalent to those obtained by a trained observer using the
cuff / stethoscope auscultation method and are within the accuracy
limits prescribed by the American National Standard for Electronic
or Automated Sphygmomanometers.
Wait 30 ~ 45 minutes before measurement if you have just consumed
caffeinated beverages or smoked cigarettes.
We recommend you to use the same wrist (preferably the left wrist) and to
measure around the same time each day.
4-2. Irregular Heartbeat Detector (IHB)
Any irregular heartbeat detected will not be stored in the memory.
The appearance of this symbol, , signifies that a certain pulse irregularity was
detected during the measurement. Talking, moving, shaking or an irregular pulse
during the measurement can result in the appearance of this icon. 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 will not replace a true cardiac examination,
but serves to detect pulse irregularities at an early stage. As a safeguard, we
recommend that if you have arrhythmias such as atrial or ventricular premature beats
and atrial fibrillation or any other special conditions you should check with your
physician before using your BPM.
The hearbeat rhythm that is more than or less than 25% from the average heart beat
intervals is usually defined as an irregular heartbeat rhythm.In order to filter the unstable
status of user and avoid affecting the detection of heart rate from any movement,
shaking or talking in the begining of measurement, the method of averaging heart beat
intervals of subject device is calculated with the three proper heart beat pulses detected
in the begining of measurement and that is different from a strict mathematical
averaging of all recorded intervals.At least 3 beats with at least 25% difference from the
average heart beat interval will generate the IHB symbol on the LCD.
When a person’s systolic and diastolic pressures fall into different
categories, the higher category should apply.
e.g. systolic pressure 181 & diastolic pressure 99 the result should
be in Red category (Severe hypertension)
systolic pressure 110 & diastolic pressure 95 Yellow category
(Mild hypertension)
When the low battery symbol appears on the display, please change the batteries.
Replace all the batteries with new ones and do not mix new and old batteries. Do not mix
alkaline, standard (carbon-zinc) or rechargeable (cadmium) batteries either. It may shorten
the battery life or cause the device to malfunction. Remove the battery cover at the side of
the unit and insert 2 pieces
AAA alkaline batteries into
the battery compartment.
Make sure the polarities
“+” and “–“ ends are
properly positioned.
