Note: The mask system does not contain latex materials. If the patient has ANY reaction to any
part of the mask system, discontinue use.
WARNINGS
This mask should be used only with CPAP or bilevel systems recommended by a
•
physician or respiratory therapist. A mask should not be used unless the CPAP or bilevel
system is turned on and operating properly.
Explanation of the Warning: CPAP or bilevel systems are intended to be used with
special masks with connectors which have vent holes or separate exhalation devices to
allow continuous flow of air out of the mask. When the CPAP or bilevel device is turned
on and functioning properly, new air from the flow generator flushes the exhaled air out
through the mask exhalation port. However, when the CPAP or bilevel device is not
operating, enough fresh air may not be provided through the mask, and exhaled air may
be rebreathed. Rebreathing of exhaled air for longer than several minutes can in some
circumstances lead to suffocation. This warning applies to most models of CPAP or
bilevel systems.
The exhaust vent flow is lower at lower mask pressures (see Pressure/Flow curve). If the
•
mask pressure during expiration is too low, there may not be enough exhaust vent flow
to completely flush the air delivery hose of exhaled air before the start of the next
inspiration.
If oxygen is used with the CPAP or bilevel device, the oxygen flow must be turned off
•
when the flow generator is not operating.
Explanation of the Warning: When the CPAP or bilevel device is not in operation, and
