Haemodynamically stable
The systolic and diastolic pressure measurements have been recorded when the circulatory system is
sufficiently at rest and are a very reliable indicator of resting blood pressure.
However, if there is an indication that the circulatory system is not sufficiently at rest (haemodynamic in-
stability), the

symbol appears in the display. In this case, the measurement should be repeated after
a period of physical and mental rest. The blood pressure measurement must be taken when the patient is
physically and mentally rested, as it will be the basis for diagnosing the blood pressure level and therefore
regulating the patient’s medical treatment.

Lack of haemodynamic stability
It is very probable that the systolic and diastolic blood pressures have been measured whilst the patient
was not at rest and the measurements therefore deviate from the blood pressure at rest. Repeat the
measurement after a minimum period of 5 minutes’ rest and relaxation. Go to a sufficiently quiet and
comfortable spot and remain there calmly; close your eyes, breathe deeply and evenly and try to relax.
If the next measurement also shows insufficient stability, you can repeat the measurement after another
resting period. If the measurements continue to show some instability, identify these blood pressure
measurements as having been taken when the circulatory system had not been sufficiently rested. In this
case, nervousness or inner anxiety may be the cause and this cannot be cured by brief periods of rest.
Existing cardiac arrhythmias may also prevent a stable blood pressure measurement. A lack of resting
blood pressure can have various causes, such as physical or mental strain or distraction, speaking or
experiencing cardiac arrhythmias during the blood pressure measurement. 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 suffering from cardiac arrhythmia or chronic mental conditions
can remain haemodynamically unstable in the long term, something which persists even after repeated
periods of rest. The accuracy of the blood pressure at rest results is reduced in these users. Like any
medical measurement method, the precision of the HSD diagnosis is limited and can lead to incorrect
results in some cases. The blood pressure measurements taken when the circulatory system was at rest
represent particularly reliable results.
