5 Operating Procedures
 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.
 WARNING:
Never obstruct the air intake port or vents for any reason.
 WARNING:
Only use the V4C-O2E Oxygen Mixer with compatible ventilators listed in Section 2.4,
Compatible Ventilators and marked with an "O2E" port. Do not attempt to use the Oxygen Mixer
with other ventilators.
 WARNING:
Ventilator-dependent patients should always be monitored by trained and competent medical
personnel. Patients should be regularly checked to ensure that the oxygen concentration
settings match with the patient condition.
 WARNING:
If at any time it is observed that excessive and consistent gas is exiting through the vents at the
back of the Oxygen Mixer, call for maintenance.
 WARNING:
If at any time a leak is suspected from or inside the V4C-O2E Oxygen Mixer, terminate use and
call for maintenance. Excessive oxygen consumption may be indicative of a leak.
 WARNING:
The inspiration trigger threshold should be carefully modified in order to avoid the risk of false
triggering or “autotriggering” of the ventilator. The least sensitive setting may result in
autotriggering. In these scenarios, auto-triggering may be reduced by decreasing the FiO
2
level
or using an inspiratory bacterial filter with a higher flow resistance. Always set an appropriate
“Max Rtot” alarm limit when using inspiration triggering with the V4C-O2E Oxygen Mixer.
