This user manual contains the information you need for the correct use of your  
S8 Elite II.  
Your Responsibility  
The owner or user of this system shall have sole responsibility and liability for any  
injury to persons or damage to property resulting from:  
operation which is not in accordance with the operating instructions supplied  
maintenance or modifications carried out unless in accordance with  
authorised instructions and by authorised persons.  
Please read this manual carefully before use.  
This manual contains special terms and icons that appear in the margins to draw  
your attention to specific and important information.  
Warning alerts you to possible injury.  
Caution explains special measures for the safe and effective use of the  
device.  
Note is an informative or helpful note.  
 
Introduction  
1
Medical Information  
About the S8 Elite II  
The S8 Elite II continuous positive airway pressure (CPAP) system is indicated  
for the treatment of obstructive sleep apnoea (OSA) in adult patients.  
The S8 Elite II CPAP system is intended for home and hospital use.  
Contraindications  
The S8 Elite II is not a life support device and may stop operating during power  
failure or certain fault conditions. It should not be used by patients who are  
dependent on continuous therapy.  
Positive airway pressure therapy may be contraindicated in some patients with  
the following pre-existing conditions:  
severe bullous lung disease  
pneumothorax  
pathologically low blood pressure  
dehydration  
cerebrospinal fluid leak, recent cranial surgery or trauma.  
Warnings  
The entire manual should be read before using the S8 Elite II.  
Advice contained in this manual should not supersede instructions given by  
the prescribing physician.  
A patient should not connect a device to the data communication port unless  
instructed to do so by their health care provider or physician. Only ResMed  
products are designed to be connected to the data communication port.  
Connecting other devices could result in injury, or damage to the S8 Elite II  
device.  
1
The S8 Elite II should be used with masks (and connectors) recommended  
by ResMed, or by a physician or respiratory therapist. A mask should not be  
used unless the S8 Elite II device is turned on and operating properly. The  
vent hole or holes associated with the mask should never be blocked.  
Explanation: The S8 Elite II is intended to be used with special masks (or  
1
connectors) 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  
1
Ports may be incorporated into the mask or in connectors that are near the mask.  
 
Medical Information  
2
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 models of CPAP devices.  
In the event of power failure or machine malfunction, remove the mask.  
The S8 Elite II can be set to deliver pressures up to 20 cm H O. In the  
2
unlikely event of certain fault conditions, pressures up to 30 cm H O are  
2
possible.  
If oxygen is used with this device, the oxygen flow must be turned off when  
the device is not operating. If oxygen has been left on while the device is not  
operating, disconnect the oxygen and wait 30 minutes before turning on the  
device.  
Explanation: When the CPAP device is not in operation and the oxygen flow  
is left on, oxygen delivered into the air delivery tubing may accumulate within  
the CPAP machine enclosure and create a risk of fire. This applies to most  
types of CPAP machines.  
Oxygen supports combustion. Oxygen should not be used while you are  
smoking or in the presence of an open flame.  
Always ensure airflow is being generated by the device before the oxygen  
supply is turned on.  
Always turn the oxygen supply off before stopping the airflow from the  
device.  
Note: At a fixed rate of supplemental oxygen flow, the inhaled oxygen  
concentration will vary, depending on where the oxygen is introduced, the  
pressure settings, patient breathing pattern, mask selection and leak rate.  
Do not use the S8 Elite II if there are obvious external defects or unexplained  
changes in performance.  
Do not open the S8 Elite II case. There are no user serviceable parts inside.  
Repairs and internal servicing should only be performed by an authorised  
service agent.  
Explosion hazard—do not use in the vicinity of flammable anesthetics.  
Cautions  
At low pressures, the flow through the exhalation ports of your mask may not  
clear all exhaled gas from the tubing. Some rebreathing may occur.  
The airflow for breathing produced by this device can be as much as 6°C  
higher than the temperature of the room. Caution should be exercised if the  
room temperature is warmer than 32°C.  
When AC mains power (100–240V AC) is not available, always use a ResMed  
DC-12 converter. (The DC-12 converter is available as an optional accessory.)  
If supplied, the ResScan™ Data Card module is designed for use with  
specific ResMed devices.  
Only use the ResScan Data Card module (if supplied) as specified in this  
manual.  
 
Medical Information

Note: The above are general warnings and cautions. Specific warnings, cautions  
and notes appear with the relevant instructions in the manual.  
Adverse Effects  
Patients should report unusual chest pain, severe headache or increased  
breathlessness to their prescribing physician. An acute upper respiratory tract  
infection may require temporary discontinuation of treatment.  
The following side effects may arise during the course of therapy with the S8  
device:  
drying of the nose, mouth or throat  
nosebleed  
bloating  
ear or sinus discomfort  
eye irritation  
skin rashes  
chest discomfort.

Frequently Asked Questions  
How will it feel when I am breathing with the S8 Elite II?  
When you first use your S8 Elite II, you may feel uncomfortable breathing against  
the airflow. This is normal. You will continue to breathe normally while you sleep.  
Take time to adjust to this new sensation.  
What do I do when I want to get up in the night?  
If you need to get up during the night, remove your mask and stop therapy.  
Always remember to restart therapy and put your mask on when you return to  
bed.  
What do I do if I feel air leaking out of the mask?  
The flow generator delivers the most effective treatment when the mask is well  
fitted and comfortable. Treatment can be affected by leaks, so it is important to  
eliminate any leaks that may arise. For example, try repositioning the mask and  
adjusting the straps.  
If you are using a nasal mask, try to keep your mouth closed during treatment.  
Air leaks from your mouth can decrease the effectiveness of your treatment. If  
mouth leaks are a problem, a full face mask or chin strap may help. Contact your  
clinician or equipment supplier for further details.  
If you are using a full face mask and you have problems trying to get a  
comfortable mask fit, contact your sleep clinic or equipment supplier. You may  
benefit from a different size or style of mask.  
You can also use the mask-fitting feature to help you fit your mask properly. See  
“Using the Mask-Fitting Feature” on page 9.  
Anything special I should do before putting the mask on?  
Before wearing your mask, wash your face to remove excess facial oils. This will  
allow a better fit and prolong the life of the mask cushion.  
Do not use moisturiser when wearing a mask.  
My mouth feels dry during treatment—what can I do?  
You may experience dryness of the nose, mouth and/or throat during the course  
of treatment, especially during winter. In many cases, a humidifier may resolve  
this discomfort. Contact your clinician for advice.  
My nose is irritated during treatment—what can I do?  
You may experience sneezing and/or a runny or blocked nose during the first few  
weeks of treatment. In many cases, nasal irritation can be resolved with a  
humidifier. Consult your clinician or equipment supplier for advice.  
Can I travel with the S8 Elite II?

transmitter manufacturer and d is the  
recommended separation distance in meters  
(m).  
Field strengths from fixed RF transmitters, as  
determined by an electromagnetic site  
a
survey, should be less than the compliance  
b
level in each frequency range.  
Interference may occur in the vicinity of  
equipment marked with the following symbol:  
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.  
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by  
absorption and reflection from structures, objects and people.  
a
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  
S8 device is used exceeds the applicable RF compliance level above, the S8 device should be observed to  
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such  
as reorienting or relocating the S8 device.  
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.

Recommended separation distances between portable and mobile RF communications  
equipment and the S8 series of devices  
The S8 series of devices is intended for use in an environment in which radiated RF disturbances are  
controlled. The customer or the user of the S8 device can help prevent electromagnetic interference by  
maintaining a minimum distance between portable and mobile RF communications equipment  
(transmitters) and the S8 device as recommended below, according to the maximum output power of the  
communications equipment.

P is the maximum output power rating of the transmitter in watts (W) according to the transmitter  
manufacturer.  
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.  
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by  
absorption and reflection from structures, objects and people.
