Internal battery CAUTION Over time, the capacity of the internal battery will decrease. This depends on individual use and ambient conditions. As the battery degrades, the battery charge level indicator may lose accuracy. This will mean battery-related and system alarms may not activate as intended. ResMed recommends the battery be tested after two years to assess the remaining battery life. Testing and replacement of the internal battery should only be performed by an authorised service agent. Note: The battery duration depends on the state of charge, the environmental conditions, the condition and age of battery, the device settings and the patient circuit configuration. In case of a mains power disruption, the device will operate using the internal battery if there is no external battery connected to the device. The internal battery will operate for approximately two hours under normal conditions (see “Technical specifications” on page 30). The power status of the battery is displayed on top of the LCD screen. Check the battery status regularly while operating the device with the internal battery and connect the device in time to mains power or alternatively to the external battery. Additionally the Internal battery use alarm will be displayed. Press the Alarm mute button to clear the alarm. To recharge the internal battery, connect the device to mains power. It can take up to three hours to fully recharge the internal battery, however this can vary depending on environmental conditions and if the device is in use.
Maintenance The internal battery has to be discharged and recharged every six months.
Remove the power cord while the Stellar is turned on (stand-by or in operation) and let the device operate with the internal battery to a charge level of 50%.
Reconnect the power cord to the mains power. The internal battery will be fully recharged.
Storing If the device is stored for a longer period the internal battery should be at the charge level of approximately 50% to increase the durability. Note: Check the charge level every six months, if necessary recharge the internal battery to a charge level of 50%.
ResMed USB stick A ResMed USB stick may be used with the device either to help the clinician to monitor your treatment or to provide you with updated device settings. For more information, see “Data management” on page 21.

Setting up for noninvasive use WARNING • •
The air filter cover protects the device in the event of accidental liquid spillage onto the device. Ensure that the air filter and air filter cover are fitted at all times. Make sure that all the air inlets at the rear of the device and under the device and vents at the mask 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. Hoses or tubes must be non-conductive and antistatic. Do not leave long lengths of the air tubing or the cable for the finger pulse sensor around the top of your bed. It could twist around your head or neck while you are sleeping.
Be careful not to place the device where it can be bumped or where someone is likely to trip over the power cord. • Make sure the area around the device is dry and clean. Notes: • ResMed recommends using the AC power cord supplied with the unit. If a replacement power cord is required, contact your ResMed Service Centre. • Place the device on a flat surface near the head of the bed.

Connect one end of the air tubing firmly onto the air outlet of the H4i.
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 H2O at 30 L/min, 5 cm H2O at 60 L/min and 16 cm H2O at 120 L/min.
Connect the mask system to the free end of the air tubing. Press the power switch on the back to turn on the device. Select the mask type (select Setup menu, then Clinical Settings, then Advanced Settings). 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 H2O) 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.
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.
Setting up for invasive use
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 a Learn Circuit when a new circuit is used or with a change of the circuit configuration, in particular when adding or removing high impedance components (eg, antibacterial filter, external humidifier, water trap or different type of air tubing). Do not connect patient interfaces prior to performing the Learn Circuit. Patient interfaces include any components placed after the ResMed Leak Valve (eg, HMEF, catheter mount, tracheostomy tube). See “Setup menu: Options” on page 18.
CAUTION When using a humidifier check the breathing system regularly for accumulated water. Notes: • When the Mask type is set to Trach, the Non-Vented Mask alarm will be automatically enabled to alert you when the ResMed Leak Valve has no vent holes or when the vent holes are blocked. • When the Mask Type is set to Trach AutoEPAP has to be turned off.

Setting up for invasive use
Using the Stellar device for the first time When using the Stellar device for the first time, ensure that all components are in working condition and perform a functional test (see “Performing a functional test” on page 13). Alarms should also be checked by the physician when setting up a new patient (see Clinical Guide).
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.
Connect the plug of the finger pulse sensor to the plug of the pulse oximeter. Connect 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 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 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.
Unlock the low flow oxygen inlet on the back of the device by pushing up on the locking clip.
Insert one end of the oxygen supply tubing into the oxygen connector port. The tubing automatically locks into place.
