SPECIAL NOTES
5
Principles of Operation
The
oxygen
conserving
regulator
is
designed
to
be
used
with
high
pressure
oxygen
systems.
It
consists
of
a
cylinder
connection,
cylinder
contents
gauge
(if
equipped),
high
to
low
pressure
regulator,
orifice
plate
and
a
conserving
demand
module.
The
regulator
reduces
the
high
pressure
of
the
cylinder
to
the
working
pressure
of
the
orifice
plate.
The
orifice
plate
uses
calibrated
orifices
to
deliver
a
selected
flow
to
the
conserving
demand
module.
The
conserving
demand
module
controls
the
pulse
size
and
timing
to
the
patient.
It
supplies
a
pulse
of
oxygen
at
the
beginning
of
each
breath.
This
reduces
the
oxygen
demand
on
the
system
and
limits
the
drying
of
the
airways.
The
flow
is
determined
by
setting
the
flow
control
knob
to
the
prescribed
flow.
The
oxygen
is
supplied
to
the
patient
though
the
cannula.
DANGER
DO
NOT
SMOKE
while
using
this
device.
Keep
all
matches,
lit
cigarettes
or
other
sources
of
ignition
out
of
the
room
in
which
this
product
is
located
and
away
from
where
oxygen
is
being
delivered.
NO
SMOKING
signs
should
be
prominently
displayed.
Textiles
and
other
materials
that
normally
would
not
burn
are
easily
ignited
and
burn
with
great
intensity
in
oxygen
enriched
air.
Failure
to
observe
this
warning
can
result
in
severe
fire,
property
damage
and
cause
physical
injury
or
death.
