ResMed Positive Airway Pressure Device S8 - Manual (Page 17)

15 General Warnings and Cautions
• In the event of power failure or machine malfunction, remove the mask.
• The S8 Lightweight 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 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 Lightweight II if there are obvious external defects or
unexplained changes in performance.
• Do not open the S8 Lightweight 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 6ºC
higher than the temperature of the room. Caution should be exercised if the
room temperature is warmer than 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.
