Mask is incorrectly assembled.
Mask may be the wrong size.

GENERAL WARNINGS

• The vent holes must be kept clear.
• The mask should only be used with CPAP or bilevel devices recommended by a
physician or respiratory therapist.
• 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 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 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 or 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.
