men can be changed (dosage modification or drug replacement) only after
agreement with your doctor.
• Do not consider the pulse frequency readings as reference values when
heart pacemaker is used.
ELECTROMAGNETIC INTERFERENCE
The device contains sensitive electronic components (microcomputer). Therefore,
avoid strong electrical or electromagnetic fields in the direct vicinity of the device
(e. g. mobile telephones, microwave cookers). These can lead to temporary impair-
ment of the measuring accuracy.
2 IMPORTANT INFORMATION
ON THE SUBJECT OF BLOOD PRESSURE
AND ITS MEASUREMENT
2.1. CAUSES AFFECTING THE BLOOD PRESSURE LEVEL
The blood pressure level is regulated by a specific region of the brain – vasomotor
center. The blood pressure change is subject to the heart force and rate as well
as the tone and lumen of blood vessels. Relaxation of the unstriated muscles of
the blood vessel walls results in pressure reduction due to the expansion of the
lumen of blood vessels.
The blood pressure level changes periodically during cardiac activity: the max-
imum value (systolic blood pressure value) is observed in the period of blood
ejection out of the heart ventricles (systole), the minimum value (diastolic blood
pressure value) is observed at the end of the relaxation period (diastole).
The blood pressure values must lie within normal ranges to prevent critical con-
dition of health.
2.2. WHICH VALUES ARE NORMAL?
The blood pressure is considered to be elevated, if at rest the diastolic pressure level
is 90 mmHg or above and/or the systolic pressure level is above 140 mmHg. In this
case, please consult your doctor. Maintenance of such pressure levels for a long pe-
riod of time pose risk to health.
Should the systolic blood pressure values lie between 140 mm Hg and 160 mm Hg
and/or the diastolic blood pressure values lie between 90 mm Hg and 100 mm Hg,
immediately, please consult your doctor. Furthermore, regular self-checks will be
necessary.
With blood pressure values that are too low, i. e. systolic values under 100 mm Hg
and/or diastolic values under 60 mm Hg, likewise, please consult your doctor.
