armchair in a quiet atmosphere for about 5 minutes before taking a measurement.
0
Remove
any
garment
that
fits
closely
to
your
upper
arm.
0
Always
measure
on
the
same
arm
(normally
left).
,
0 Always compare measurements taken at the same time of day, since blood pressure
changes
during
the
course
of
the
day,
as
much
as
20-40
mmHg.
5.2.
Common
sources
of
error:
Note: Comparable blood pressure measurements always require the .same
conditions!
Conditions
should
always
be
quiet.
0 All efforts by the user to support the arm can increase blood pressure. Make sure
youare
in
a'comfortable,
relaxed
position
and
do
not
flex
any
of
the
muscles
in
the
measurement arm during the measurement. Use a cushion for support if necessary.
0 If the arm artery lies considerably lower or higher than the heart, an erroneously
high or low blood pressure will be measured! Each 15cm (6 inch) difference in height
between
your
heart
and
the
cuff
results
in
a
measurement
error
of
10
mmHgl
0.:
Cuffs
that
are
too
narrow
or
too
short
result
in
false
measurement
values.
Selecting
the correct cuff is extremely important. Cuff size is dependent upon the circumfer-
ence of the arm (measured in the center). The permissiblerange is printed on the
cuff.
lfthis
is
not
suitable
for
your
use,

-- Aloose cuff or a sideways protruding air pocket causes false measurement values.
0 With repeated measurements, blood accumulates in the arm, which can lead to
false results. Consecutive blood pressure measurements should be repeated after a
1 minute pause or after your arm has been held up in order to allow the accumulat-
ed blood to flow ,
If you decide to take your Averaging Mode measurement again be sure to Wait at
least one minute beforehand.
