 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
2
Sensor Calibration for
calibration instructions.
 WARNING:
Never use the V4C-O2E Oxygen Mixer without appropriately setting both high and low FiO
2
alarms
on the compatible ventilator or FiO
2
monitor.
 WARNING:
Never use the V4C-O2E Oxygen Mixer without appropriately setting both high and low pressure/
volume alarms on the compatible ventilator.
 WARNING:
Setting any alarm limits to OFF or extreme high or low values can cause the associated alarm not
to activate during ventilation, which reduces its ability for monitoring the patient and alerting the
clinician to situations that may require intervention.
 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:
Before starting ventilation, ensure that the V4C-O2E Oxygen Mixer and compatible ventilator are
properly assembled and that the system's air intake filter and cooling vents are not obstructed.
Refer to Section 2.6, Device Features for the locations of these features. Also ensure that the
patient circuit is of the proper configuration (double or single limb), properly connected to the
ventilator, and that the circuit hoses are neither damaged nor compressed and contain no
obstructions or foreign bodies.
The operational verification and safety checks listed in Table 9-1 below should be performed to
ensure the Oxygen Mixer is operating properly in the following circumstances:
• Prior to using the V4C-O2E Oxygen Mixer with a patient
