(SpOr)

(pulse

3.
Getting to
know
your
device
The
SPO 25
pulse
oximeter
provides
a non-invasive
measurement
of the
arterial oxygen
saturation
(Spor)
and the heart
rate
(pulse
rate).
oxygen
saturation
indicates
the
peic-entage
of
haemoglobin
in
adenal
blood that
is loaded
with oxygen.
Therefore
it is
an important
parair-
eter for
assessing
the
respiratory
{unction.
To take
a measurement,
the
pulse
oximeter
uses
two
rays of light
wlth
differing
wavelengths,
which
strike
the finger
inserted
inside the
housing.
A low
oxygen
saturation
varue
generailt
indicates
underlying
irlriesses (respiratory
diseases,
"
asthma,
heart fai
ure
etc,).
People
with
a low
oxygen
saturation
value are
more likely
to experience
the iollowing
symp_
toms:
shodness
of breath, increased
head rate,
weakness,
neryousness
and
outbreiki
oi
sweating.
lf
oxygen
saturation is
known
to be chronically
drminished,
it requires
monitorlng
us-
ing
the
pulse
oximeter
under
medical
supervision.
rfyou
have
acutery
dimihisned
oxygen
iatu-
ration,
with.or
without the
accompanying
symptoms,
you
must consult
a doctor imme'diatety
as it could
lead to
a life{hreatening
situation. The
pulie
oximeter
is
pafticularly
suitable for
patients
at risk
such as
peopre
witi
head
disease
or asthma,
but
ar;;for
athl6tes
and neitthy
people
who
exercise
at high
altitude
(e.g.
