dicator always indicates the higher range – "high normal" in the
example described.
Note that these default values are for general guidance
only, as individual blood pressures may vary.
Please note that self-measurement at home usually results in val-
ues lower than those recorded at a doctor's surgery. Consult your
doctor at regular intervals. Only they are able to give you personal
target values for controlled blood pressure, particularly if you are
receiving medical therapy.
Low blood pressure
 WARNING
Low blood pressure (hypotension) can be a health hazard and
cause dizziness or fainting. Blood pressure is considered low if
systolic and diastolic pressure are below 90/60 mmHg (source:
National Health Service, 2023).
Seek medical attention if you suddenly suffer from low blood
pressure.
Resting indicator (using HSD diagnostics)
One of the most common errors made when taking a blood pres-
sure measurement is not ensuring that the user's circulatory sys-
tem is sufficiently at rest when taking the measurement. In this
case, the measured systolic and diastolic blood pressure values
do not represent the blood pressure at rest. However, it is this
blood pressure at rest that should be used to assess the meas-
ured values.
This blood pressure monitor uses integrated haemodynamic sta-
bility diagnostics (HSD) to measure the user's haemodynamic
stability when taking the blood pressure measurement. This ena-
bles it to indicate whether the blood pressure was taken when the
user's circulatory system was sufficiently at rest.
The measured blood pressure value was obtained
when the user's circulatory system was sufficiently
at rest and reliably represents the blood pressure
at rest.
Indicates that the value was obtained when the
user's circulatory system was not sufficiently at
rest. The blood pressure values measured in this
case generally do not represent the blood pressure
at rest. The measurement should therefore be
repeated after a period of physical and mental rest
lasting at least 5 minutes.
No resting During the measurement it was not possible to
indicator determine whether the user's circulatory system
symbol is was sufficiently at rest. In this case too, the meas-
displayed urement should be repeated after a period of rest
lasting at least 5 minutes.
The user's circulatory system not being sufficiently at rest can
be the result of various factors, such as physical stress, mental

strain/distraction, speaking or experiencing cardiac arrhythmia
during the measurement.

In an overwhelming number of cases, HSD will give a very good
guide as to whether the user's circulatory system is rested when

a blood pressure measurement is taken.
However, certain patients suffering from cardiac arrhythmia or
chronic mental conditions may remain haemodynamically unsta-
ble even in the long-term, something which persists even after
repeated periods of rest. The accuracy of the results for the blood
pressure at rest is reduced in these users.
Like any medical measurement method, the precision of HSD is
limited and it can lead to incorrect results in some cases. Never-
theless, the blood pressure measurements taken when the user's
