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
