Pathophysiology
Respiratory
failure
can
arise
from
an
abnormality
in
____________________
of
the
components
of
the
respiratory
system
,
including
the
airways
,
____________________
,
central
nervous
system
(
CNS
)
,
peripheral
nervous
system
,
respiratory
muscles
,
and
chest
wall
.
Patients
who
____________________
hypoperfusion
secondary
to
cardiogenic
,
hypovolemic
,
or
septic
shock
often
____________________
with
respiratory
failure
.
Ventilatory
capacity
is
the
maximal
spontaneous
ventilation
that
can
be
____________________
without
development
of
respiratory
muscle
fatigue
.
Ventilatory
____________________
is
the
spontaneous
minute
ventilation
that
results
in
a
____________________
PaCO2
.
Normally
,
ventilatory
capacity
greatly
exceeds
ventilatory
demand
.
Respiratory
____________________
may
result
from
either
a
reduction
in
ventilatory
____________________
or
an
increase
in
ventilatory
demand
(
or
both
)
.
Ventilatory
capacity
can
be
____________________
by
a
disease
process
involving
any
of
the
____________________
components
of
the
respiratory
system
and
its
controller
.
Ventilatory
demand
is
____________________
by
an
increase
in
minute
ventilation
and
/
or
an
____________________
in
the
work
of
breathing
.
