• noninvasive ventilation, see “Setting up for noninvasive use” on page 4.

• invasive ventilation, see “Setting up for invasive use” on page 5.

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, it could lead to
battery related alarms and or system errors. 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 27). 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.

1 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%.

2 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 19.

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.

CAUTION

• 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.

1 Connect the power cord.
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 9).

4

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
and 16 cm H

O at 120 L/min.

2

O at 30 L/min, 5 cm H2O at 60 L/min

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 Select the mask type (select Setup menu, then Clinical Settings, then Advanced Settings).
7 Perform Learn Circuit (see “Setup menu: Options” on page 16).

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

O) the use of a water trap will avoid water spillage back into the air circuit.

2

• 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.

English

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).

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.

• 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.

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.

1 Connect the plug of the finger pulse sensor to the plug of the pulse oximeter.
2 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 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 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.

of the device, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.
Recommended separation distance:

Conducted RF
IEC 61000-4-6

Radiated RF
IEC 61000-4-3

NOTE 1: Ut is the AC mains voltage prior to application of the test level.
NOTE 2: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 3: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection
from structures, objects and people.

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,
amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the
electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location in which the device is used exceeds the applicable RF compliance level above, the device
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as reorienting or relocating the device.

b

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Recommended separation distances between portable and mobile RF communications equipment and the
device

The device is intended for use in an environment in which radiated RF disturbances are controlled. The customer or
the user of the device can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the device as recommended below, according
to the maximum output power of the communications equipment.

where P is the maximum output power rating of
the transmitter in watts (W) according to the
transmitter manufacturer and d is the
recommended separation distance in metres (m).

Environmental information This device must be disposed of in accordance with the laws

and regulations of the country in which disposal occurs.

The crossed-out wheeled bin symbol indicates that the product bearing this symbol
may not be disposed of together with general household waste, but instead requires
separate disposal. This requirement for separate disposal is based on the European
Directive 2002/96/EC for electrical and electronic equipment, and the European Directive
2006/66/EC for batteries. You can hand in the product at a municipal collection point, for
example. This reduces the impact on natural resources and prevents contamination of the
environment through the release of hazardous substances.

Batteries containing more than 0.0005 percent of mercury by mass, more than 0.002
percent of cadmium by mass or more than 0.004 percent of lead by mass are marked

General warnings and cautions

WARNINGS

A warning alerts you to possible injury.

• Read the entire manual before using the device.

• This device should only be used with air tubing and accessories recommended by

ResMed or the prescribing clinician. Use of incorrect air tubing and accessories may
affect the functioning of this device.

• The device and the accessories are to be used for the specified intended use only.

• The device must only be used with masks (and connectors

ResMed, or by a clinician or respiratory therapist. A mask should not be used unless
the device is turned on and operating properly. The vent hole or holes associated with
the mask should never be blocked.

Explanation:

which have vent holes to allow continuous flow of air out of the mask. When the device
is turned on and functioning properly, new air from the device flushes the exhaled air out
through the mask vent holes. However, when the device is not operating, insufficient
fresh air will be provided through the mask, and the exhaled air may be rebreathed.
Rebreathing of exhaled air for longer than several minutes can, in some circumstances,
lead to suffocation. This applies to most Positive Airway Pressure devices.

• In the event of power failure2 or machine malfunction, remove the mask or the
catheter mount from the tracheostomy tube.

• Explosion hazard – do not use in the vicinity of flammable anesthetics.

• Do not use the device if there are obvious external defects, unexplained changes in

performance.

• Only use orignal and approved ResMed accessories and parts.

•

Use only accessories from the original package. If the packaging is damaged, the
respective product must not be used, and should be disposed along with the packaging.

• Before using the device and the accessories for the first time, ensure that all
components are in a proper condition and that their operational safety is guaranteed. If
there are any defects, the system should not be used.

•

Additional equipment connected to medical electrical equipment must comply with the
respective IEC or ISO standards (eg, IEC 60950 for data processing equipment).
Furthermore all configurations shall comply with the requirements for medical electrical
systems (see IEC 60601-1-1 or clause 16 of the 3Ed. of IEC 60601-1, respectively).
Anybody connecting additional equipment to medical electrical equipment configures a
medical system and is therefore responsible that the system complies with the
requirements for medical electrical systems. Attention is drawn to the fact that local
laws take priority over the above mentioned requirements. If in doubt, consult your local
representative or the technical service department.
