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.

2Medical Information
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.
•The S8 Elite II should be used with masks (and connectors)1recommended
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
connectors)1which 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.

3Medical Information
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 H2O. In the
unlikely event of certain fault conditions, pressures up to 30 cm H2O are
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.

4Medical Information
Note: The above are general warnings and cautions. Specific warnings, cautions
and notes appear with the relevant instructions in the manual.

WARNING
A mask should not be used unless the S8 Elite II device is powered and
operating properly.
5When ramping begins, the LCD will display the word "RAMPING", with the
current pressure indicated as dashes. Each dash is approximately equivalent to
2 cm H2O. For example, 6 dashes represents approximately 12 cm H2O
pressure.
SmartStart™
The S8 Elite II has a function called SmartStart™that your clinician can enable. If
SmartStart is enabled, your device will start automatically when you breathe into
your mask, and will stop automatically when you take your mask off. This means
you do not have to press the Start/Stop key to begin or end treatment.
Note: Do not use SmartStart when using a mask with an anti-asphyxia valve,
such as the Mirage Full Face Mask.
Stopping Treatment
To stop treatment at any time, remove your mask and press the Start/Stop key
or
if your clinician has enabled SmartStart, simply remove your mask and treatment
will end.

9How to Use the S8 Elite II
Using the Mask-Fitting Feature
You can use the S8 Elite II mask-fitting feature to help you fit your mask properly.
This feature delivers air pressure for a three-minute period, prior to starting
treatment, during which you can check and adjust your mask fit to minimise
leaks.
Note: Make sure that the mask setting on the MASK screen is the same as the
mask you are using.
To use the mask-fitting feature:
1Fit your mask as described in the mask user instructions.
2Hold down the Start/Stop key for at least three seconds until air pressure
delivery starts.
The following display will appear on the LCD screen indicating that the mask-
fitting feature is operating. Your S8 device will ramp to the mask-fit pressure and
will remain at this pressure for three minutes.
The LCD also displays a mask-fit star rating. See Table 1, “Definitions of Mask-
Fit Star Rating,” on page 10.
Note: The mask-fit star rating display disappears after three minutes.
The mask-fitting feature can only be started from the RAMP screen.
The mask-fit pressure is the set treatment pressure or 10 cm H20, whichever is
greater.
3Adjust your mask, mask cushion, and headgear until you have a secure and
comfortable fit.
Once you have a secure and comfortable fit, check your mask-fit star rating on
the LCD screen. Table 1 explains the mask-fit star ratings.
Note: If there is another person nearby to check your mask-fit star rating, you
can adjust your mask, mask cushion and headgear while lying down.
4After three minutes, the pressure reverts to the set pressure and treatment will
begin.
•If you do not wish to wait three minutes, hold down the Start/Stop key
for at least three seconds to start treatment immediately.
•If you press the Start/Stop key for less than three seconds, the unit will
return to standby mode (the RAMP screen is displayed).
