Common question of blood pressure
measurement
1. What is blood pressure?
Blood pressure is the force exerted by blood
against the walls of the arteries. Systolic pressure
occurs when the heart contracts. Diastolic
pressure occurs when the heart expands. Blood
pressure is measured in millimetres of mercury
(mmHg). One's natural blood pressure is
represented by the fundamental pressure, which
is measured first thing in the morning while one is
still at rest and before eating.
2. What is Hypertension and how is it controlled?
Hypertension, an abnormally high arterial blood
pressure, if left unattended can cause many
health problems including stroke and heart attack.
Hypertension can be controlled by altering
lifestyle, avoiding stress, and with medication
under a doctor's supervision. To prevent
Hypertension or keep it under control: Do not
smoke, exercise regularly, reduce salt and fat
intake, have regular physical checkups, maintain
proper weight.
3. Why measure Blood Pressure at home?
Blood pressure measured at a clinic or doctor's
office may cause apprehension and can produce
an elevated reading, 25~30mmHg higher than
that measured at home. Home measurement
reduces the effects of outside influences on blood
pressure readings, supplements the doctor's
readings and provides a more accurate, complete
blood pressure history.

Common question of blood pressure
measurement
Common question of blood pressure
measurement
4. WHO Blood Pressure Classification?
Standards to assess high blood pressure, without
regard to age, have been established by the world
Health Organization (WHO), as shown below:
Note: There is no definition about hypopiesia,
and generally SYS (systolic pressure) less
than 90mmHg or DIA (diastolic pressure) less
than 60mmHg is called hypotension.
5. Blood pressure variations?
An individual's blood pressure varies greatly on a
daily and seasonal basis. It may vary by 30 to 50
mmHg due to various conditions during the day. In
hypertensive individuals variations are even more
pronounced. Normally, the blood pressure rises
while at work or play and falls to its lowest levels
during sleep. So do not be overly concerned by
the results of one measurement. Take
measurements at the same time every day using
the procedure described in this manual to get to
know your normal blood pressure. Regular
readings give a more comprehensive blood
pressure history. Be sure to note date and time
when recording your blood pressure. Consult
doctor to interpret the blood pressure data.
6. When is the best time to measure blood
pressure?
After urination, before breakfast in the morning.
Before sleeping at night.
Before taking medicine.
Please keep a stable body state and mind every
time measuring. We suggest taking
measurements at a same time every day.
