3. Blood pressure information
To determine your blood pressure, you need to measure two values:
■ ■
SYS – The systolic (upper) blood pressure: this is generated when the heart
contracts and the blood is pumped into the blood vessels.
■ ■
DIA – The diastolic (lower) blood pressure: this is the pressure when the heart
is relaxed and fills with blood again.
■ ■
The measured values for blood pressure are displayed in mmHg.
To better evaluate the results, there is a traffic-light-colour system on the left side
of the Veroval
®
duo control that directly describes the results to enable easier
categorisation of the measured value. The World Health Organisation (WHO) and
the European Society of Cardiology (ESC) & European Society of Hypertension (ESH)
have developed the following summary for classifying blood pressure values:
Results

Evaluation Systolic

Diastolic
pressure
Red Grade 3 hypertension above 179 mmHg and/or above 109 mmHg
Orange Grade 2 hypertension 160–179 mmHg and/or 100 –109 mmHg
Yellow Grade 1 hypertension 140–159 mmHg and/or 90–99 mmHg
Green High normal 130–139 mmHg and/or 85–89 mmHg
Green Normal 120–129 mmHg and/or 80–84 mmHg
Green Optimal up to 119 mmHg and up to 79 mmHg

■ ■
Established hypertension (high blood pressure) is defined as having a systolic
value of at least 140 mmHg and/or a diastolic value of at least 90 mmHg.
■ ■
Generally, blood pressure is described as being too low (hypotension) when
the blood pressure value is less than 105 mmHg (systolic) and 60 mmHg
(diastolic). However, the threshold between normal and low blood pressure
(hypotension) is not as accurately specified as the threshold for high blood
pressure (hypertension). Hypotension may be indicated by symptoms such as
dizziness, tiredness, tendency to faint, visual disorders or a high pulse rate. In
order to ensure that hypotension or the associated symptoms are not signs of
a serious illness, a doctor should be consulted in the event of doubt.
