X. Troubleshooting
• GO
2
VENT™
stops cycling
1. Leak in circuit / look for pressure leak at gas connections,
gas supply, patient airway, ET tube cuff, etc.
2. Compliance change / change in patient’s lung compliance
may affect breathing rate, adjust rate dial accordingly.
3. Increased gas flow / an increase in supply gas flow will
elevate PEEP. Adjust rate dial out (counter-clockwise)
accordingly.
4. Out of gas / replace oxygen cylinder or connect to other
gas source.
5. Assisted breathing mode / the GO
2
VENT™
is waiting for
patient to trigger the inspiration.
• Breathing (exhalation)
rate is too fast
1. High supply flow / reduce supply gas flow.
2. Low PIP setting / increase PIP as needed.
3. Compliance too high (stiff lung) / change mode of
ventilation.
4. Low exhalation resistance / set rate dial down (clockwise)
• Breathing (exhalation)
rate is too slow
1. Low supply flow / increase supply gas flow.
2. High PIP setting / decrease PIP as needed.
3.
Compliance too low (soft lung) / change mode of
ventilation.
4. High exhalation resistance / adjust rate dial out (counter-
clockwise).
• Inspiratory time is too
long
1. Supply gas flow too low / increase supply gas flow.
2. High PIP setting / lower PIP setting as appropriate.
3. Compliance too low / change mode of ventilation.
• Inspiratory time is too
short
1. Supply gas flow too high / decrease supply gas flow.
2. Low PIP setting / increase PIP setting as appropriate.
3. Compliance too high / change mode of ventilation.
• Reading on pressure
manometer increases or
decreases
1. PIP increase / look for airway occlusion or kinked ET tube,
change in patient’s lung compliance, verify PIP setting.
2. PIP decrease / look for change in patient’s lung
compliance, verify PIP setting on GO

VENT™.
• Flow on my regulator
does not go to 40 L/min
1. GO
2
VENT™
can operate at flows as low as 15 L/min
2. Maximum flow is 40 L/min per ASTM guideline
3. If you have a 15-16 L/min flowmeter connected to a 50
PSIG piped-in gas source, the maximum flow to
GO
2
VENT™
is self-limited to 40 L/min when you flush
open the flowmeter.
• Maximum flow 40 L/min
is not enough
1. Maximum flow is 40 L/min per ASTM guideline.
2. Patient can entrain additional room air through the one-
way valve to meet their inspiratory flow demand for
spontaneously breathing patient.
• What is the tidal volume
delivered?
1. Tidal volume delivered is a function of flow rate (liters per
minute) over inspiratory time (seconds).
2. GO
2
VENT™
delivers gas until the set PIP is reached.
