The bar graph in the display and the scale on the unit indi-
cate the range of the blood pressure which has been
recorded. If the values for systolic and diastolic pressure are
in two different WHO ranges (e.g. systolic in the "high-nor-
mal" range and diastolic pressure in the "normal" range) the
graphic WHO classification on the unit indicates the higher
range ("high-normal" in the example described).
5.4 Resting indicator measurement (using hsD
diagnostics)
The most frequent error made when measuring blood pres-
sure is taking the measurement when not at rest (haemo-
dynamic stability), which means that both the systolic and
the diastolic blood pressures are incorrect in this case. Dur-
ing blood pressure measurement, the device automatically
determines whether the circulatory system is sufficiently at
rest or not.

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 circulatory system is not sufficiently at rest
(haemodynamic instability), the symbol
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 a diagnosis
and regulation of the patient's medical treatment.
