Introduction
The OMRON MX3 Plus measures your blood pressure and pulse simply and quickly
from the arm, without the use of an inflation bulb or stethoscope. The measurement
values are stored in the memory of the OMRON MX3 Plus.
The OMRON MX3 Plus includes a standard cuff for arm circumferences ranging from
22-32 cm. Optional large cuffs (32-42 cm) can be applied.

9 General information about blood pressure
Blood circulation
Health and blood pressure
The blood circulation is responsible for
supplying the body with oxygen. Blood
pressure is the pressure exerted on the
arteries.
The systolic blood pressure value (higher
pressure or top value) represents the
The incidence of hypertension increases
with age. In addition, a lack of exercise,
excess body fat and high levels of choles-
terol (LDL), which sticks to the inside in
blood vessels, reduces elasticity of these
vessels. Hypertension accelerates arterial
blood pressure produced by contraction of sclerosis which can lead to very serious
the heart muscle.
conditions such as stroke and myocardial
infarction. For these reasons it is very
important to know whether the blood
pressure is within a healthy range. Blood
pressure fluctuates from minute to minute,
throughout the day. Therefore it is essential
to take regular measurements to help you
identify an average blood pressure.
The diastolic blood pressure value (lower
pressure or lower value) represents the
blood pressure produced by relaxation of
the heart muscle.
Classification of blood pressure
The World Health Organisation (WHO)
and the International Society of
Hypertension (ISH) developed the blood
pressure classification. This classification
is based on the blood pressure values
measured while sitting on a chair in the
outpatient department of a hospital.
Symptoms of high blood pressure
High blood pressure can go unnoticed for
a long time, since it does not cause notice-
able symptoms. The following are all
possible causes of abnormally high blood
pressure:

disorders or endocrine disturbance
tension may cause your blood pressure to
be higher than in familiar circumstances at
home. This is known as “White Coat
Hypertension”.
Treatment of high blood pressure
If your blood pressure reaches upper
values of 140 - 160 mmHg and lower
values of 90 - 95 mmHg in repeated
measurements over several days, you
should consult your doctor for detailed
medical examination. You can assist the
treatment prescribed by your doctor in the
following ways:
• Loose weight and lower your cholesterol
level by reducing the calories and fat in
your diet. Cut down on animal fats and
eat more fruit and vegetables.
• Reduce the consumption of alcohol.
• Reduce the intake of salt: the German
League for Combating High Blood
Pressure recommends six grams of salt
per day (i.e. one teaspoon) on average.
• Stop smoking.
Blood pressure measurement
Measuring your blood pressure daily
enables you to recognize high blood
pressure at an early stage and obtain
medical treatment.
The oscillometric method of measurement
determines your blood pressure by
measuring the pressure fluctuations
caused by the pulse waves.
Since your blood pressure fluctuates
within a day (see graphic next page), you
should always measure it at the same
time each day to ensure that the
measurements are genuinely comparable. • Take regular exercise.
At the doctor’s surgery, nervousness and
