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.

General Warnings and Cautions
!
WARNINGS
•Read the entire guide before using the S8 Series II.
•Advice contained in this guide 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 Series II
device.
•The S8 Series 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 Series II device is turned on and operating properly. The
vent hole or holes associated with the mask should never be blocked.
Explanation: The S8 Series II is intended to be used with special masks (or
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
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 PAP devices.
•In the event of power failure or machine malfunction, remove the mask.
•The S8 Series 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.
* Ports may be incorporated into the mask or in connectors that are near the mask.

•If oxygen is used with this device, the oxygen flow must be turned off when
the device is not operating.
If the oxygen has been left on, turn off the device, then wait 30 minutes
before turning on the device again.
Explanation: When the PAP device is not in operation and the oxygen flow is
left on, oxygen delivered into the air delivery tubing may accumulate within
the PAP machine enclosure and create a risk of fire. This applies to most
types of PAP 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 Series II if there are obvious external defects or
unexplained changes in performance.
•Do not open the S8 Series 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 11ºF
(6ºC) higher than the temperature of the room. Caution should be exercised if
the room temperature is warmer than 90ºF (32ºC).
•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. It
is not supplied with all models.)
Note: The above are general warnings and cautions. Specific warnings,
cautions, and notes appear with the relevant instructions in the manual.
