5Setting up for invasive use
English
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.
•For optimal accuracy and synchrony, perform 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 16.
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 16). 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 port and an uncuffed or
deflated cuff tracheostomy tube.
WARNING
•When using a Heated Moisture Exchange Filter (HMEF), replace the HMEF
regularly as specified in the instructions provided with the HMEF.
•The H4i is contraindicated for invasive use. An external humidifier approved for
invasive use is recommended according to EN ISO 8185 with an absolute
humidity of > 33 mg/L.
•For optimal accuracy and synchrony, perform 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 16.
CAUTION
When using a humidifier check the breathing system regularly for accumulated
water.
Note: When the mask type is set to Tr a c h , the Non-Vented Mask alarm will be
automatically enabled to alert you when the leak port has no vent holes or when the vent
holes are blocked.

Working with other optional accessories
Attaching the pulse oximeter
Use of a pulse oximeter may be recommended by your clinician.
Contraindication
The pulse oximeter does not meet defibrillation-proof requirement per IEC 60601-1: 1990,
clause 17.h.
1Connect the plug of the finger pulse sensor to the plug of the pulse oximeter.
2Connect the plug of the pulse oximeter at the rear of the device.
To view the oximetry values, from the Monitoring menu, select Monitoring.
Adding supplemental oxygen
Oxygen may be prescribed by your clinician.
Note: Up to 30 L/min at maximum oxygen pressure of 50 mbar (0.73 psi) can be added.
WARNING
•Oxygen flow must be turned off when the device is not operating, so that unused
oxygen does not accumulate within the device and create a risk of fire.
•Use only certified, clean oxygen sources.
•ResMed strongly recommends adding oxygen into Stellar’s oxygen inlet at the
rear of the device. Entraining oxygen elsewhere, ie into the breathing system via
a side port or at the mask, has potential to impair triggering and accuracy of
therapy/monitoring and alarms (eg, High Leak alarm, Non-vented mask alarm). If
used in this way, therapy and alarm operation must be verified each time oxygen
flow is adjusted.
•Oxygen supports combustion. Oxygen must not be used while smoking or in the
presence of an open flame. Only use oxygen supply in well-ventilated rooms.
•The breathing system and the oxygen source must be kept at a minimum
distance of 6’ 6” (2 m) away from any sources of ignition (eg, electrical devices).
•
Oxygen must not be used while the device is being operated within the mobility bag.

Tailoring treatment setup options
Setting Ramp
Ramp time is a feature that can be enabled
by your clinician by setting a maximum ramp
time. Designed to make the beginning of
treatment more comfortable, ramp time is
the period during which the pressure
increases from a low start pressure to the
treatment pressure. See “Setup menu:
Options” on page 16.
Programs
If the Clinician has selected both, ie, dual,
you can choose the program to use on the
Treatment screen. If only a single program is
selected, the option does not display.
Using mask-fit
You can use mask-fit to help you fit your mask properly. This feature delivers constant
treatment pressure for a three-minute period, prior to starting treatment, during which you
can check and adjust your mask-fit to minimise leaks. The mask-fit pressure is the set
CPAP or EPAP pressure or 10 cm H2O, whichever is greater.
1Put the mask on according to the mask user guide.
2Hold down for at least three seconds until pressure delivery starts.
3 If necessary adjust the mask, mask cushion and headgear until you have a good mask fit.
After three minutes treatment will begin. Mask-fit can be stopped at any time by pressing .
Notes:
•Press for at least three seconds during mask-fit to start the treatment immediately.
•The mask-fitting feature is disabled when the mask type Tr a c h is selected.
