Blood Pressure Monitor Intended Use:
1

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, the lowest is the diastolic blood pressure. Both
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. What is blood pressure ?
Having one's blood pressure measured by a doctor in a
hospital or a clinic, and a group health checks, tend to stimulate
nervousness in the subject and may even create high blood
pressure. Also varies blood pressure 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
2. Why is it useful to measure blood pressure
at home ?

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.
A. WHO blood pressure classifications
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. * Figure No.1
B. Variations in blood pressure
The graph below illustrated
the variations in blood
pressure over a whole day
with measurement taken
every five minutes.
* Figure No.2
Individual blood pressures vary greatly both on a daily and a
seasonal basis. These variations are even more pronounced
in hyper tense patients. Normally the blood pressure rises
while at work and is at its lowest during sleeping period.
(Hyper tense: means a person who has high blood
pressure symptom.)
3

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.
Wait 30 ~ 45 minutes before measurement if you’ve just
consumed caffeinated beverages or smoked cigarettes.
Blood pressure measurements should be interpreted by a
physician or trained health professional who is familiar with
your medical history. By using the unit regularly and recording
the results for your physician to interpret, you keep your
physician informed of the continuing trends in your blood
pressure.
Wind the cuff snugly around your wrist and the cuff must be at
the same level as your heart.
Do not vibrate the unit during measurement, or the proper
measurement will not be achieved.
3. Important information before use of the unit
4

Perform measurement quietly in a relaxed position.
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.
People with a condition that causes circulatory problems
(diabetes, kidney disease, arteriosclerosis or poor peripheral
circulation) may get lower readings with this monitor that
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 measurement determine with the unit are
equivalent to those obtained by a trained observer using
the cuff / stethoscope auscultation method. Within the limits
prescribed by the American National Standard for Electronic
or Automated Sphygmomanometers.
