WARNING:
To reduce the risk of infection, wash your hands thoroughly before and after handling the Oxygen
Mixer or its accessories.
WARNING:
While the V4C-O2E Oxygen Mixer-Ventilator system is in use, an alternative means of ventilation
should always be available in the event of a problem with the Oxygen Mixer. This is particularly
true for ventilator-dependent patients. Supplementary observation, appropriate for the patient's
condition, is also recommended.
1.2.2 Warnings Regarding Installation and Accessories
WARNING:
Always perform recommended tests of the compatible ventilator per its manual and the
recommended V4C-O2E Oxygen Mixer tests in Section 9.2, Functional Tests prior to connecting a
patient.
WARNING:
Never perform tests that could disrupt ventilation while the patient is being ventilated. Always
provide an alternate means of ventilation where applicable.
WARNING:
Before starting ventilation, ensure that the device is properly assembled and confirm that the
Oxygen Mixer's air intake port and vents are not obstructed.
WARNING:
Do not use unauthorized accessories with the V4C-O2E Oxygen Mixer system. Use of incorrect
accessories can lead to malfunction or damage to the device.
WARNING:
Do not use V4C-O2E Oxygen Mixer with ventilators that are missing rubber feet. If a ventilator is
missing any of its rubber feet, see instructions in Section 4.1, Installation and Assembly on how to
install replacement feet which are supplied with the V4C-O2E Oxygen Mixer. Similarly, do not use
V4C-O2E Oxygen Mixer if its rubber feet are missing.
WARNING:
Do not place anything in the space between the bottom of the ventilator and the top of the V4C-
O2E Oxygen Mixer. Cooling vents located in this space may become compromised.
