2
Plug the free end of the power cord into a power outlet.
3
Attach the H4i heated humidifier to the front of the Stellar.
If the H4i is not in use, and if applicable, connect the antibacterial filter firmly onto the air
outlet of the device (see “Attaching an antibacterial filter” on page 10).
Note:
Other external humidifiers can be used for noninvasive setup. ResMed
recommends using a breathing system (including antibacterial filter, air tubings, external
humidifier) with an impedance of maximum 2 cm H

4
Connect one end of the air tubing firmly onto the air outlet of the H4i.
5
Connect the mask system to the free end of the air tubing.
6
Press the power switch on the back to turn on the device.
7
Select the mask type (select
Setup
menu, then
Clinical Settings
, then
Advanced Settings
).
8
Perform Learn Circuit (see “Setup menu: Options” on page 18).
Attaching the H4i heated humidifier for noninvasive use
Use of the H4i heated humidifier may be recommended by your clinician. For information
on using the H4i, see the H4i user guide.
WARNING
•
Always place the H4i on a level surface below the level of the patient to prevent
the mask and tubing from filling with water.
•
Make sure that the water chamber is empty and thoroughly dried before
transporting the humidifier.
•
The H4i heated humidifier is not intended for mobile use.
•
Do not overfill the water chamber, as during use this will cause water to spill into
the air circuit. Check the air circuit regularly for accumulated water. If you observe
water has spilled into the air circuit, clear the water and check that the water
chamber is not overfilled. When using the H4i at high pressures (above 25 cm
H
2
O) the use of a water trap will avoid water spillage back into the air circuit.
•
For optimal accuracy and synchrony, perform a Learn Circuit with a change of the
circuit configuration, in particular when adding or removing high impedance
components (eg, antibacterial filter, external humidifier, water trap, nasal pillow
type mask or air tubing). See “Setup menu: Options” on page 18.
CAUTION
Check the air circuit for water condensation. Use a water trap or a tubing wrap if
humidification is causing water condensation within the tube.
Notes:
•
A humidifier increases resistance in the air circuit and may affect triggering and cycling, and
accuracy of display and delivered pressures. Therefore perform the Learn Circuit function
(see “Setup menu: Options” on page 18). The device adjusts the airflow resistance.
•
The heating feature of the H4i is disabled when the device is not mains powered.
Setting up for invasive use
The Stellar can be used invasively only with the ResMed Leak Valve, or using an uncuffed
or deflated cuff tracheostomy tube with the ResMed Leak Port (24976).
AutoEPAP is contraindicated for invasive use.
WARNING
•
Make sure that all the air inlets at the rear of the device and under the device and
vents at the mask or at the ResMed Leak Valve are unobstructed. If you put the
device on the floor, make sure the area is free from dust and clear of bedding,
clothes or other objects that could block the air inlets.
•
When using a Heated Moisture Exchange Filter (HMEF), replace the HMEF
regularly as specified in the instructions provided with the HMEF.
