not be performed properly. Observe the
chapter on error messages/troubleshooting
in these instructions for use and repeat the
measurement.
• Now select the desired user memory by pressing the
M1 or M2 memory buttons. If you do not select a user
memory, the measurement is stored in the most re-
cently used user memory. The relevant symbol
appears on the display.
• Using the Start/stop button
pressure monitor. The measurement is then stored in
the selected user memory.
If you forget to turn off the device, it will switch off
automatically after approx. one minute. In this case too,
the value is stored in the selected or most recently used
user memory.
• Wait for at least 1 minute before taking
another measurement.
Evaluating results
General information about blood pressure
• Blood pressure is the force with which the bloodstream
presses against the arterial walls. Arterial blood pressure
constantly changes in the course of a cardiac cycle.
• Blood pressure is always stated in the form of two values:
or
, switch off the blood
– The highest pressure in the cycle is called systolic blood
pressure. This arises when the heart muscle contracts and
blood is pumped into the blood vessels.
– The lowest is diastolic blood pressure, which is when the
heart muscle has completely stretched back out and the
heart fills with blood.
• Fluctuations in blood pressure are normal. Even during
repeat measurements, considerable differences between the
measured values may occur. One-off or irregular measure-
ments therefore do not provide reliable information about the
actual blood pressure. Reliable assessment is only possible
when you perform the measurement regularly under compa-
rable conditions.
Cardiac arrhythmia
This device can identify potential disruptions of the heart
rhythm when measuring and, if necessary, indicates this
after the measurement with the symbol
indicator for arrhythmia. Arrhythmia is an illness in which the
heart rhythm is abnormal because of flaws in the bioelectrical
system that regulates the heartbeat. The symptoms (skipped
or premature heart beats, pulse being slow or too fast) can be
caused by factors such as heart disease, age, physical make-
up, excess stimulants, stress or lack of sleep. Arrhythmia can
only be determined through an examination by your doctor. If
the symbol appears frequently, please consult your doc-
tor. Only they are able to determine any arrythmia during an
examination.
