The WHO classification in the display shows the range of the
measured blood pressure.
If the values for systolic and diastolic pressure are in two dif-
ferent WHO ranges (e.g. systolic in the grade
hypertension
range and diastolic pressure in the normal range), the WHO
classification on the unit always indicates the higher range
(grade
hypertension in the example described).
5.6 Resting indicator measurement (using HSD diagnostics)
The most frequent error made when measuring blood pressure
is taking the measurement when not at rest (haemodynamic
stability), which means that both the systolic and the diastolic
blood pressures are incorrect in this case. During blood pres-
sure measurement, the device automatically determines wheth-
er the circulatory system is sufficiently at rest or not.
If there is no indication that the circulatory system is not suf-
ficiently at rest,
(haemodynamic stability) is displayed and
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 dias-
tolic 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.
Table for classification of blood pressure values (unit of measurement mmHg) for adults:
Range Systolic Diastolic Action
Hypotonia (degraded blood pressure) lower than 105 lower than 60 Check with doctor
Normal range between 105 and 120 between 60 and 80 Self check
Pre-hypertensive blood pressure range* between 120 and 140 between 80 and 90 Check with doctor
High blood pressure - degree between 140 and 160 between 90 and 100 Consult your doctor
High blood pressure - degree higher than 160 higher than 100 Consult your doctor
