General Warnings - ResMed AirFit F20 User Manual

GENERAL WARNINGS


The mask must be used under qualified supervision for users who
are unable to remove the mask by themselves. The mask may not
be suitable for those predisposed to aspiration.

The mask must be fitted with the supplied elbow (containing the
valve and vent assembly) to ensure safe and functional usage
unless otherwise specified. Do not use the mask if the valve or
vent assembly is damaged or missing.

The elbow, valve and vent assembly have specific safety
functions. The mask should not be worn if the valve is damaged
as it will not be able to perform its safety function. The elbow
should be replaced if the valve is damaged, distorted or torn. The
vent holes and valve should be kept clear.

The mask should only be used with CPAP or bilevel devices
recommended by a physician or respiratory therapist.

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.
