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.
