•
Avoid connecting flexible PVC products (eg, PVC
tubing) directly to any part of the mask. Flexible PVC
contains elements that can be damaging to the
materials of the mask, and may cause the components
to crack or break.
•
The mask should not be used unless the device is
turned on. Once the mask is fitted, ensure the device is
blowing air.
Explanation: CPAP and bilevel devices are intended to
be used with special masks (or connectors) which have
venting 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.
•
The F20 line of full face CPAP masks are not intended
to be used simultaneously with nebulizer medications
that are in the air path of the mask/tube.
•
As with all masks, some rebreathing may occur at low
CPAP pressures.
•
Refer to your CPAP or bilevel device manual for details
on settings and operational information.
•
Remove all packaging before using the mask.
