Introduction
S8 AutoSet Spirit II
The S8 AutoSet Spirit II self-adjusting sleep apnea system is indicated for the treatment
of obstructive sleep apnoea (OSA) in adult patients. The S8 AutoSet Spirit II self-
adjusting sleep apnoea system has two treatment modes: AutoSet and fixed-pressure
CPAP. The S8 AutoSet Spirit II system is intended for home and hospital use.
S8 AutoScore II
The S8 AutoScore II continuous positive airway pressure (CPAP) system is indicated for
the treatment of obstructive sleep apnoea (OSA) in adult patients. The S8 AutoScore II
CPAP system is intended for home and hospital use.
Contraindications

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.
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 CPAP device:
•drying of the nose, mouth, or throat
•nosebleed
•bloating
•ear or sinus discomfort
•eye irritation
•skin rashes

4Press or until you see the setting that you require.
5Press to apply.
Using the Mask-fitting Feature
You can use the S8 Series 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.
1Fit your mask as described in the mask user instructions.
2With the RAMP or SETTLING screens displayed, hold down for at least
three seconds until air pressure delivery starts.
Your device will ramp to the mask-fit pressure and will remain at this pressure
for three minutes.
The following displays on the LCD screen indicating that the mask-fitting feature
is operating, where: ***** is an excellent fit;****- is a very good fit; ***-- is a
good fit; while **---, *---- and ----- each require you to adjust your mask.
3Adjust your mask, mask cushion and headgear until you have a secure and
comfortable fit.
After three minutes, the pressure reverts to the set pressure and treatment will
begin. If you do not wish to wait three minutes, hold down for at least
three seconds to start treatment immediately.
If you press for less than three seconds, the unit will return to standby
mode (the RAMP or SETTLING screen).
Starting Treatment
1Make sure the power is on.

spillage onto the device. Ensure the air filter and air filter cover are fitted
at all times.
Servicing
This device is intended to provide safe and reliable operation when operated and
maintained in accordance with the instructions provided by ResMed. To ensure that

11Frequently Asked Questions
!
CAUTION
•Do not attempt to open the S8 Series II case. There are no user
serviceable parts inside.
•Inspection and repair should only be performed by an authorised agent.
Under no circumstances should you attempt to service or repair the S8
Series II yourself.
Frequently Asked Questions
How will it feel when I am breathing with the S8 Series II?
When you first use your S8 Series II device, you may feel uncomfortable breathing
against the airflow. This is normal. You will continue to breathe normally while you
sleep. The EPR setting may also improve comfort. 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 S8 Series II 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 clinician or equipment supplier. You may benefit from a different
size or style of mask.
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 Series II?
Your S8 Series II has an internal power supply that enables it to operate in other
countries. It will operate on power supplies of 100–240V and 50/60Hz. No special
adjustment is necessary, but you will require an approved power cord for the region in
which you are using the device.
Your S8 Series II device automatically adjusts to changes in altitude up to 2,591 m.

12
Please consult the medical services department of your carrier if you intend to use your
S8 Series II on an aircraft. The S8 Series II complies with US FCC Part 15, Class B
requirements.
Note: Do not use your S8 Series II while the aircraft is taking off or landing.
Can I use my S8 Series II if mains (AC) power is not available?
A DC-12 converter is available to connect the S8 Series II to a 12V or 24V DC power
source. Contact your clinician for details.
Troubleshooting
If there is a problem, try the following suggestions. If the problem cannot be solved,
contact your equipment supplier or ResMed. Do not attempt to open the device.
Problem/Possible Cause Solution
No display
Power is not connected. Ensure the power cable is connected and the power
switch (if available) is on.
Insufficient air delivered from S8 Series II device
Ramp or settling time is in use. Wait for air pressure to build up or change ramp or
settling time.
Air filter is dirty. Replace air filter.
Air tubing is kinked or punctured. Straighten or replace tubing.
Air tubing not connected properly. Check air tubing.
Mask and headgear not positioned
correctly.
Adjust position of mask and headgear.

Power cord not connected properly. Connect power cord firmly at both ends.
Power outlet may be faulty. Try another power outlet.
Leak Alert has been enabled by your

SmartStart.
Take a deep breath in and out through the mask.

13Troubleshooting
Excessive leak. Adjust position of mask and headgear.
