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.
• 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 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 H
2
O. In the
unlikely event of certain fault conditions, pressures up to 30 cm H
2
O are
possible.
• 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.
* Ports may be incorporated into the mask or in connectors that are near the mask.
