(2) Connect the other end of the tube to the mask according to the user manual for
the mask.
WARNINGS!
• If you are using a mask with a built-in exhalation port, connect the mask’s
connector to the tube.
• If you are using a mask with a separate exhalation port, connect the tube to the
exhalation port. Position the exhalation port so that the vented air is blowing away
from your face. Connect the mask’s connector to the exhalation port.
• If you are using a full-face mask (a mask covering both your mouth and nose), the
mask must be equipped with a safety (entrainment) valve.
• In order to minimize the risk of CO2rebreathing, the patient should observe the
following instructions:
- Use the accompanying tube and mask provided by 3B Medical, Inc.
- Do not wear the mask for more than a few minutes while the device is not
operating.
- Use only masks with vent holes. Do not block or try to seal the vent holes in the
exhalation port.
12.5 Using Oxygen with the Device
Oxygen may be added at the mask connection. Please observe the instructions
listed below when using oxygen with the device.
WARNINGS!
• Connect the oxygen tube to the oxygen inlet of the mask.
• The oxygen supply must comply with the local regulations for medical oxygen.
• Turn on the device before turning on the oxygen. Turn off the oxygen before
turning off the device. Explanation of Warning: When the device is turned off, but
the oxygen flow still exists, oxygen may accumulate within the device's enclosure
and pose a fire hazard. Turning off the oxygen before turning off the device will
prevent oxygen accumulation in the device and reduce the risk of fire. This warning
applies to CPAP devices.
• Oxygen supports combustion. Keep the device and the oxygen container away
from heat, open flames, any oily substances, or other sources of ignition. DO NOT
smoke in the area near your Luna GII or the oxygen container.
• Sources of oxygen should be located more than 1 m from the device.
• When using oxygen with this system, a Pressure Valve must be placed in-line with
the patient circuit between the device and the oxygen source. The pressure valve
helps prevent the backflow of oxygen from the patient circuit into the device when
the unit is off. Failure to use the pressure valve could result in a fire hazard.
• Do not connect the device to an unregulated or high pressure oxygen source. The
pressure of oxygen source does not exceed the work pressure of the device.
