6. Connect the free end of the air tubing firmly onto the nasal cannula.
See the nasal cannula user guide for detailed information.
Recommended nasal cannulas are available on ResMed.com/support.
Recommended water type
The following water types are recommended for use in the humidifier:
• Boiled tap water, cooled to room temperature
• Distilled water
• Bottled water (with a low mineral content).
Note: Do not use non-sterile demineralised water for domestic use.

Adding supplemental oxygen

Your Lumis HFT device is designed to be compatible with levels of supplemental oxygen up to 10
L/min.
WARNING
• Always make sure that the device is turned on and airflow generated before the oxygen
supply is turned on. Always turn the oxygen supply off before the device is turned off, so
that unused oxygen does not accumulate within the device enclosure and create a risk of
fire.
• Supplemental oxygen must not be used while smoking or in the presence of an open
flame.
• Supplemental oxygen must only be added into your device oxygen inlet at the rear of the
device. Adding oxygen elsewhere, ie, into the breathing system via tube, will affect the
delivered flow volume, temperature and humidity.
CAUTION
Do not connect supplemental oxygen input directly to a medical gas pipeline system, oxygen
bottle or other high pressure oxygen source. A flow regulator must be fitted to ensure the
delivered oxygen remains at or below 10 L/min.
For advice on connecting to an oxygen source, contact your homecare provider.
To add supplemental oxygen:
1. Unlock the low flow oxygen input at the rear of the device by pushing down on the locking clip.
2. Insert one end of the oxygen supply tubing into the low flow oxygen input. The tubing will
automatically lock into place.
3. Attach the other end of the oxygen supply tubing to the oxygen supply.
4. Start therapy.
5. Turn on oxygen and adjust (at the oxygen supply) to the prescribed flow rate.
