Safety Information
1-8 User Manual
DMR V4C 3.3 (User Manual) V-4 06-May-2022
WARNING:
Turn off oxygen supply if abnormal behavior of the device is observed and provide the patient
with an alternative means of ventilation.
WARNING:
Oxygen flow to the ventilation system will begin automatically when an active breathing mode is
selected. The V4C-O2E Oxygen Mixer will terminate oxygen flow when the ventilator is not in an
active breathing mode.
WARNING:
In the event of power loss to the ventilator, oxygen delivery to the Oxygen Mixer will cease
immediately. Safety valves on the V4C-O2E Oxygen Mixer ensure that room air is always available
to the ventilator in all fault conditions, including in an oxygen loss scenario.
WARNING:
Never use the V4C-O2E Oxygen Mixer and the low pressure oxygen port of the compatible
ventilator simultaneously. Only one source of oxygen can be delivered to the ventilator during
use.
WARNING:
Do not connect high pressure oxygen directly to the ventilator. Always follow the instructions on
the compatible ventilator when using its low flow oxygen port to deliver oxygen.
WARNING:
In the event of an oxygen leak, shut down the supply of oxygen at its source. In addition, remove
and/or keep any incandescent source away from the device, which may be enriched with oxygen.
Circulate fresh air into the room to bring the oxygen level down to normal.
WARNING:
The electrical connecting cable between the V4C-O2E Oxygen Mixer and the compatible ventilator
delivers power to the Oxygen Mixer. It will automatically begin oxygen delivery when the
ventilator enters an active ventilation state. Disconnecting this cable will cease power and oxygen
delivery to the V4C-O2E Oxygen Mixer.
1.2.6 Warnings Regarding Alarms and Troubleshooting
WARNING:
Never use the V4C-O2E Oxygen Mixer without an appropriate FiO
2
monitor. Always ensure that
the sensor has been properly calibrated before use. See Section 5.1, FiO
