Parts Of The Mask; Fitting The Mask - ResMed Ultra Mirage User Manual

familiarise yourself with the functioning of
the anti-asphyxia valve membrane which
automatically closes when the flow
generator starts operating, and opens as
soon as the flow generator stops. Test its
functioning by fitting the mask firmly
against your face and sealing the swivel
end of the valve with your hand. You
should then still be able to breathe freely.
The mask should not be worn if the anti-
•
asphyxia valve membrane is damaged or
missing. If the valve membrane is
damaged, distorted or torn, it should be
replaced with a new valve membrane.
The exhaust vent flow is lower at lower
•
mask pressures (see Pressure/Flow
Curve— section A). 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.
The mask may not be suitable for those
•
at increased risk of gastric regurgitation.
The mask must be cleaned and
•
disinfected/sterilized if it is used
between patients. Refer to the section
"Cleaning the Mask between Patients"
for details.
If oxygen is used with the flow
•
generator, the oxygen flow must be
turned off when the flow generator is
not operating.
Explanation of the Warning: When the
flow generator is not in operation and
the oxygen flow is left on, oxygen
delivered into the air delivery tubing
may accumulate within the flow
generator enclosure and create a risk of
fire. This applies to most types of flow
generators.
Oxygen supports combustion. Oxygen
•
should not be used while you are
smoking or in the presence of an open
flame.
Always ensure airflow is being
•
generated by the device before the
oxygen supply is turned on.
Always turn the oxygen supply off
•
before stopping the airflow from the
device.
Please refrain from smoking while
•
oxygen is in use.
Using a mask may cause tooth, gum or
•
jaw soreness or aggravate an existing
dental condition. If symptoms occur,
consult your physician or dentist.
Note: At a fixed flow rate of supplemental
oxygen flow, the inhaled oxygen concentration
will vary, depending on the pressure settings,
patient breathing pattern, mask selection and
the leak rate.
