the measurement can be recorded as a reliable resting blood
pressure value.
: haemodynamic stability
Measurement of the systolic and diastolic pressure is increased
when the circulatory system is sufficiently at rest and is a very
reliable indicator of resting blood pressure. However, if the cir-
culatory system is not sufficiently at rest (haemodynamic insta-
bility), the symbol
is displayed.
In this case, the measurement should be repeated after a pe-
riod of physical and mental rest. The blood pressure measure-
ment must be taken when the patient is physically and mentally
rested, as it will be the basis for a diagnosis and regulation of
the patient’s medical treatment.
: lack of haemodynamic stability
It is very probable that the measurement of systolic and di-
astolic blood pressure has not been carried out at rest and has
therefore distorted the measurement.
Repeat the measurement after a rest and relaxation period of at
least 5 minutes. Go to a sufficiently calm and comfortable spot
and remain there calmly; close your eyes, breathe deeply and
evenly and try to relax.
If the following measurement shows a lack of stability again,
repeat the measurement after another period of rest. In case of
further unstable measurements, identify these measurements
as they were taken when the circulatory system had not be suf-
ficiently rested.
In this case, inner unrest of the nervous system could be the
cause, which cannot be cured by brief periods of rest. Devel-
oping cardiac arrhythmia can also prevent stable blood pres-
sure measurements.
A lack of resting blood pressure can have various causes, such
as physical or mental strain or distraction and speaking or
experiencing heart rhythmic disturbance during the measure-
ment.
In an overwhelming number of cases, the HSD diagnosis will
give a very good guide as to whether the circulatory system is
rested when taking the measurement. Certain patients suffer-
ing from cardiac arrhythmia or chronic mental conditions can
remain haemodynamically unstable in the long-term, some-
thing which persists even after repeated periods of rest. The
precision of the results of the resting blood pressure is reduced
in these users. Like any medical measurement method, the
precision of the HSD diagnosis is limited and can lead to incor-
rect results in some cases. The blood pressure measurements
taken when the circulatory system was at rest represent par-
ticularly reliable results.
6. Saving, retrieving and deleting results
The computer automatically saves the blood pressure readings
of the last 60 measurements. When the 60 memory locations
are exceeded, the current oldest value is deleted.
You can display the memory as follows:
•
Press the “User-Switching key” to select a memory zone,
and press the “M” key to switch from memory to memory
with sequence numbers.
•
The average value “AVG” of the last three measurements is
displayed first.
•
Continue pressing the memory button to recall other indi-
vidual measurement results - the first result to appear is that
of the most recent value measured.
•
Press the On/Off switch to turn the unit off.
