Cautions - ResMed S8 AutoSet Spirit II Clinical Manual

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 CPAP devices.
•
In the event of power failure or machine malfunction, remove the mask.
•
The S8 AutoSet Spirit II can be set to deliver pressures up to 20 cm H
the unlikely event of certain fault conditions, pressures up to 30 cm H
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 and leak rate.
•
Do not use the S8 AutoSet Spirit II if there are obvious external defects or
unexplained changes in performance.
•
Do not open the S8 AutoSet Spirit 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 anaesthetics.

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 air flow for breathing produced by this device can be as much as 6ºC
higher than the temperature of the room. Caution should be exercised if the
room temperature is warmer than 32ºC.
Note: The above are general warnings and cautions. Specific warnings, cautions
and notes appear with the relevant instructions in the manual.
