: 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. Develop-
ing cardiac arrhythmia can also prevent stable blood pressure
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.
8. Calling up stored values
You can call up values from the 2 user memories and display
the averages.
•
Press the M1 or M2 memory buttons. Firstly, the average of
all values stored in this user memory will be displayed. This
is denoted by the letter “A” in the display.
•
If you press the memory buttons again, further individu-
al measurements appear with WHO, cardiac arrythmia and
HSD. These individual values are numbered from 1 to 60. The
time and date are alternately displayed after 2.5 seconds.
•
If there are 60 individual values in the memory at the same
time, the oldest value is deleted in order to make room for
the new value.
•
Use the start/stop button to turn off the device, or it will
turn off automatically after approx. 30 seconds.
Tip: You can also use the 2 user memories to separately store
measurements – e.g. mornings and evenings.
Deleting stored values
To delete an entire user memory, you have to select the rele-
vant user memory. The average is displayed and denoted with
the letter “A”. Press and hold memory button M1 or M2 until the
display flashes and keep pressing the button until the display
completely switches off.
