Set-up
WARNING: Do not use the V4C-O2E™ Oxygen Mixer without an inspiratory bacterial filter between the ventilator’s outlet
and the patient. Doing so can cause cross-contamination of the Oxygen Mixer or delivery of contaminants to the patient.
WARNING: In the event of power loss to the ventilator or Oxygen Mixer, oxygen delivery to the Oxygen Mixer will cease
immediately. Safety valves on the Oxygen Mixer ensure that room air is always available to the ventilator in all fault
conditions, including in an oxygen loss scenario.
NOTE: For assembly instructions see Section 4 of the User Manual on the USB provided.
1) Attach the gas connection tube and adapter from the Oxygen Mixer air outlet to the ventilator (see label 1 on figure).
Ensure the tube is not pinched or kinked along its length and that no filter is present between the gas connection tube
and the ventilator.
2) Install the V4C-O2E electrical connecting cable from the compatible ventilator O2E port to the Oxygen Mixer (see label 2
on figure).
3) Confirm that the air intake filter (see label 3 on figure) is
present and is not visibly soiled. Replace the air intake filter
by pinching and removing the filter and installing a new one if
the filter is soiled, missing, incorrectly installed, or damaged.
Ensure that the filter is sitting flush with the Oxygen Mixer.
4) Confirm the oxygen hose has the correct connectors for the
oxygen supply used. Connect the oxygen hose to the oxygen
inlet (see label 4 on figure). Connect the opposite end of the
hose to an oxygen source.
5) Always complete the Operational Verification Checklist and
Functional Tests (Section 9 of the User Manual) prior to
starting ventilation.
CAUTION: The Oxygen Mixer is rated for 20-80 psi (138-551 kPa)
oxygen sources. Using higher or lower pressure oxygen sources
can interfere with the operation of the Oxygen Mixer. Always
ensure there is sufficient flow of oxygen.
NOTE: Oxygen delivery to the Oxygen Mixer is initiated
automatically when the ventilator enters an active ventilation mode. Oxygen flow is terminated automatically when the
ventilator is not actively ventilating or is powered off.
