Measures human's Systolic blood pressure, Diastolic blood
pressure and heart rate on wrist by oscillometric measurement
method.
The device is designed for home use and recommended for
use by adults aged 18 years and older with wrist circumference
ranging 135 ~ 195 mm.
Blood Pressure Monitor Intended Use:
1

Blood pressure is a measurement of the force of blood owing
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 inuence 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 rst 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
difcult to record the fundamental blood pressure, but to come

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 classications
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.

B. Variations in blood pressure
The graph below illustrated
the variations in blood
pressure over a whole day
with measurement taken
every ve 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.)

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.
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 reects 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.
This product is not suitable for pregnant women.
