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 connectors1) recommended by 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: The Stellar is intended to be used with special masks (or connectors1) 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
•No modification of this equipment is allowed.
CAUTIONS
A caution explains special measures for the safe and effective use of the device.
•When using accessories, read the manufacturer’s User Manual. For consumables important information can be provided on the packaging, see also symbols on page 31.
•At low pressures, the flow through the mask vent holes may be inadequate to clear all exhaled gas, and some rebreathing may occur.
•The device may not be exposed to excessive force.
•If the device should fall accidentally on the ground, please contact your authorised service agent.
•Pay attention to leaks and other unusual sounds. If there is a problem, contact an authorised service agent.
1 Ports may be incorporated into the mask or in connectors that are near the mask.
2 During partial (below rated minimum voltage) or total power failure, therapy pressures will not be delivered. When power is restored, operation can be proceeded with no change to settings.
