ResMed Quattro Air Manuel D'utilisation page 10

Explanation: CPAP and bilevel devices are 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 holes. When the device is turned off, the mask valve
opens to atmosphere allowing fresh air to be breathed.
However, a higher level of exhaled air may be rebreathed
when the device is off. This applies to most full face masks
for use with CPAP and bilevel devices.

Follow all precautions when using supplemental oxygen.

Oxygen flow must be turned off when the CPAP or bilevel
device is not operating, so that unused oxygen does not
accumulate within the device enclosure and create a risk of
fire.

Oxygen supports combustion. Oxygen must not be used
while smoking or in the presence of an open flame. Only
use oxygen in well ventilated rooms.

At a fixed rate of supplemental oxygen flow, the inhaled
oxygen concentration varies, depending on the pressure
settings, patient breathing pattern, mask, point of
application and leak rate. This warning applies to most
types of CPAP or bilevel devices.

The technical specifications of the mask are provided for
your clinician to check that they are compatible with the
CPAP or bilevel device. If used outside specification or if
used with incompatible devices, the seal and comfort of the
mask may not be effective, optimum therapy may not be
achieved, and leak, or variation in the rate of leak, may
affect the CPAP or bilevel device function.

Discontinue using this mask if you have ANY adverse
reaction to the use of the mask, and consult your physician
or sleep therapist.

Using a mask may cause tooth, gum or jaw soreness or
aggravate an existing dental condition. If symptoms occur,
consult your physician or dentist.
