INTRODUCTION
The
oxygen
conserving
regulator
includes
a
combination
of
low
‐
pressure
regulator
and
an
oxygen
conserver,
designed
for
use
with
a
cylinder
as
an
ambulatory
oxygen
system.
It
is
capable
of
delivering
a
precise
amount
of
supplemental
oxygen
at
the
optimal
point
in
the
breathing
cycle.
The
conserver
greatly
increases
the
efficiency
in
the
delivery
of
oxygen,
maximizing
the
beneficial
effects
and
eliminating
unnecessary
oxygen
waste.
When
we
breathe,
approximately
one
‐
third
of
the
time
is
spent
inhaling
and
two
‐
thirds
exhaling.
As
a
result,
oxygen
delivered
by
continuous
flow
is
wasted
during
exhalation.
By
eliminating
oxygen
flow
during
exhalation,
a
two
‐
thirds
savings
is
possible.
Additionally,
the
oxygen
available
during
the
very
first
part
of
inhalation
contributes
mostly
to
meet
oxygen
needs.
The
oxygen
conserving
regulator
takes
advantage
of
these
facts
to
provide
maximum
efficiency
in
the
delivery
of
oxygen.
This
device
is
designed
to
be
an
integral
component
of
a
lightweight,
long
‐
lasting
ambulatory
oxygen
system.
