2. How does the
GO
2
VENT™
function during
inhalation and
exhalation?
The GO
2
VENT™ is a small automatic gas-powered resuscitator
intended to provide pressure-limited, flow controlled ventilatory
support for short-term emergency ventilatory support for both
breathing and non-breathing patients while being monitored by
a clinician or trained operator. The GO
2
VENT™ is a single patient,
multiple use device.
• During inhalation, exhalation will not start until the desired
peak inspiratory pressure (PIP) is reached.
• During exhalation, inhalation will not begin until pressure drops
to the controlled positive end-expiratory pressure (PEEP).
3. What is the
definition of
“pressure
control” mode
(mandatory
breathing) and
“pressure
support” mode
(assisted
breathing) when
used with
GO
2
VENT™?
For non-breathing patients - the mode of ventilation is called
pressure control because no effort is required by the patient to
initiate inhalation (mandatory breathing).
For patients taking spontaneous breaths requiring assisted
breathing - If the rate dial has been adjusted to a position that
the continuous flow of gas creates more pressure than the set
PEEP, then the GO
2
VENT™ will not go into inhalation until the
patient draws the baseline pressure down to PEEP. Again,
because the GO
2
VENT™ is cycled on both set PIP and PEEP,
inhalation will not start until pressure reaches the set PEEP
value. This mode of ventilation is called pressure support
because the GO
2
VENT™ only delivers ventilatory support when
initiated by the patient.
4. How do I set the
GO
2
VENT™ in
pressure control
or pressure
support mode?
Which mode the GO
2
VENT™
is in is simply a function of where
the rate dial has been adjusted. Turn the rate dial clockwise until
it is in pressure support (assisted breathing) mode. For pressure
control (mandatory breathing) mode, turn the rate dial counter
clockwise.
5. What does the
rate dial do?
The rate dial is a variable resistor which controls the rate at
which gas may escape. When the rate dial has been adjusted to
a position where the continuous flow of gas does not create more
pressure than the set PEEP (set PEEP is approximately 1/5
th
of
the set PIP), upon completion of exhalation, the GO
2
VENT™
will
automatically cycle into inhalation because it
cycles on both the
set PIP and PEEP.
6. Does the gas
supplied to the
GO
2
VENT™ flow
continuously
during exhalation
and inhalation?
Yes
