 WARNING:
Never use the V4C-O2E Oxygen Mixer without appropriately setting both high and low pressure/
volume alarms on the compatible ventilator.
 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 V4C-O2E
Oxygen Mixer or delivery of contaminants to the patient.
 WARNING:
If the Oxygen Mixer's air intake filter appears visibly soiled, replace it even if the recommended
maintenance period has not yet elapsed.
5.1 FiO
2
Sensor Calibration
If using the V4C-560 Ventilator FiO
2
kit, each time a measurement cell is removed and reinstalled,
and on a weekly basis, the FiO
2
sensor must be recalibrated before using the ventilator.
Follow steps in Section 5.1.1, Calibrating the V4C-560 FiO
2
Kit for Use with the V4C-O2E Oxygen
Mixer to ensure the most accurate calibration procedure. This process does not require the use of
a measurement device.
If using an alternative FiO
2
sensor, follow all instructions and warnings of that sensor to ensure
proper calibration.
5.1.1 Calibrating the V4C-560 FiO
2
Kit for Use with the V4C-O2E Oxygen Mixer
As the ventilator initially warms, the FiO
2
sensor's warming may cause it to drift out of calibration,
therefore a two-step calibration is recommended whereby the sensor is first calibrated cold and
then re-calibrated once it has warmed.
1. Confirm that the V4C-O2E Oxygen Mixer is correctly installed as per Section 4.1, Installation and Assem-
bly.
2. Set-up the ventilator according to its labeling and manual, including running any functional tests.
3. Complete the Operational Verification Checklist per Section 9.1, Operations Verification Checklist,
including the Functional Tests (Section 9.2, Functional Tests).
4. Calibrate the FiO
2
sensor. If using the V4C-560 Ventilator FiO
2
kit, calibrate per the instructions in the
V4C-560 Ventilator Clinician's Manual. This includes disconnecting the sensor from the T-connector
and exposing it to room air, waiting 15-30s, and calibrating the sensor.
5. Start ventilating with desired settings.
