What
is
an
Sp02
Measurement?
22
How ScanWatch obtains an
Sp02
measurement:
-
Sp02
stands
for
peripheral
capillary
oxygen
saturation, an
estimate
of
the
amount
of
oxygen
in
the
blood.
More specifically,
it
is
the
percentage
of
oxygenated
hemoglobin
(hemoglobin
containing
oxygen)
compared
to
the
total
amount
of
hemoglobin
in
the
blood
(oxygenated
and
non-oxygenated
hemoglobin).
-
Hemoglobin
is
a
protein
that
carries
oxygen
in
the
blood
to
your
organs.
It
is
found
inside red
blood
cells
and
gives
them
their
red color.
Once
oxygen
is
in
our
organs,
it
acts
as
the
fuel
that
allows
our
cells
to
work.
-
Sp02
is
measured
by
pulse oximetry.
It
works
by
emitting
and
then
absorbing
a
light
wave
reflecting
the
blood
vessels,
or
capillaries, in
the
wrist.
- ScanWatch uses a
multi-wavelength
sensor called
PPG
(photoplethysmography)
sensor
that
emits
and
measures red
and
infrared
reflections
on
the
blood
vessels in
the
wrist. The
algorithm
then
compares
the
reflection
at
each
wavelength
to
compute
the
Sp02
value.
- Variations in
oxygen
saturation
are
normal.
But
if
you
are
short
of
breath
or
if
you have
pulmonary
issues,
oxygen
saturation
levels can
drop,
because less
oxygen
is
entering
your
organs. Elevation,
heart
and
lungs issues,
and
sleep
disorders
can
affect
your
Sp02
level.
If
you
are
experiencing
any
symptoms
or
have concerns,
contact
your
physician.
If
you
believe
you
are
experiencing
a
medical
emergency,
contact
emergency
services.
