Mirage Kidsta™ Nasal Mask

ENGLISH

The MIRAGE KIDSTA™ NASAL MASK is
intended for multipatient use for children
aged seven and over, prescribed
continuous positive airway pressure
(CPAP) or bilevel therapy in hospital, clinic
and/or home environments.

MEDICAL INFORMATION

Note: The mask system does not contain

latex materials. If you have ANY reaction to
any part of the mask system, discontinue
use and consult your sleep therapist.

. WARNINGS AND CAUTIONS

• Your physician should determine the

degree of arousability before
commencing CPAP treatment. Use of
secondary sensing devices such as
apnoea monitors and transcutaneous
carbon dioxide monitors is advisable.
These will help determine whether
nasal CPAP treatment should be
applied.

• Ensure that the nasal cushion does not

block the nostrils at any time during
fitting or use.

• The MIRAGE KIDSTA is designed to

provide a stable, effective air seal with
minimum headgear tension. High
headgear tension may lead to facial
deformities with long-term use. Regular
clinician review of growth patterns and

the use of different styles of mask is
recommended.

• The mask contains small parts which

could result in a choking risk. Your
clinician should assess the suitability of
the selected mask.

• This mask should be used only with

flow generators recommended by your
physician or respiratory therapist. A
mask should not be used unless the
flow generator is turned on and
operating properly. The exhaust vent
should never be blocked.
Explanation of the Warning: Flow
generators are intended to be used
with special masks with connectors
which may have vent holes or separate
exhaust vents to allow continuous flow
of air out of the mask. When the flow
generator is turned on and functioning
properly, new air from the flow
generator flushes the exhaled air out
through the attached mask exhaust
vent. However, when the flow
generator is not operating, enough
fresh air will 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
flow generators.

• At low CPAP pressures, the flow

through the exhaust vent may be

ENGLISH

inadequate to clear all exhaled gas from
the tubing. Some rebreathing may occur.
Explanation of the Warning: The
exhaust vent flow is lower at lower mask
pressures (see Pressure/Flow curve—
Figure A). To avoid rebreathing it is
recommended that a mask pressure of

O or more be used.

4cmH

2

• The MIRAGE KIDSTA features an elbow

that can be easily removed while the
mask is fitted. The mask should not be
used with the elbow attached unless the
flow generator is turned on and
operating properly.

• 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 ventilator tubing may
accumulate within the flow generator
enclosure. Oxygen accumulated in the
flow generator will create a risk of fire.
This warning applies to most types of
flow generators.

• Please refrain from smoking while

oxygen is in use.

Note: At a fixed rate of supplemental

oxygen flow, the inhaled oxygen
concentration will vary, depending on the
pressure settings, patient breathing pattern,
mask selection and leak rate.

PARTS OF THE MASK

See Figure B.

FITTING THE MASK

See Figure C.

Note: Before fitting the mask, refer to the

section “Cleaning the Mask in the Home”.

1 Place the headgear on the head. Adjust

the side vertical straps so that the lower
strap sits just below the ear (not
touching it) and at the base of the head
(Fig. C-1).

2 The headgear clip should be parallel

with the nose and not in the line of
vision. Check that the crossover is as far
forward as possible (Fig. C-2).
To adjust the crossover to a forward
position, slide the crossover buckle
along one strap (Fig. C-2a) and then
along the other strap (Fig. C-2b).
Alternate the movement on each side
until the crossover is as far forward as
possible.

3 Ensure that the crossover and the rear

straps lie flat against the head.

4 Place the mask on the nose (Fig. C-3).

Clip the mask to the headgear.

5 Adjust the lower straps by pulling firmly

(Fig. C-4) so that the rear straps fit

securely around the base of the head
(Fig. C-4a).

Note: Ensure that the nostrils are not

blocked by the cushion.

6 Connect one end of the main air tubing

to your flow generator and the other
end to the swivel.

Note: The swivel, short air tubing and

mask elbow are supplied assembled.

7 Turn your flow generator on.
8 Connect the mask elbow to the mask

frame. To do this, hold the sides of the
mask elbow (Fig. C-5) and firmly push
the elbow onto the mask frame until it
clicks into place.

Check that you have connected the
mask elbow correctly by rotating it. Be
careful not to squeeze the sides of the
elbow. If the mask elbow is fitted
correctly, it should rotate freely and not
separate from the mask frame.

9 Adjust the angle of the mask by selecting

the setting that provides a comfortable
fit with minimum or no leak.
To test each setting, hold down the
Angle Selector Tab (Fig. C-6) and move
the headgear clip up or down
(Fig. C-6a) as required. You may need
to raise the headgear clip when moving
it from one setting to the next.
The mask can be tilted at five different
positions. If you feel excessive pressure
on the middle of the nose, tilt the mask
down. Alternatively, if you feel excessive
pressure on your upper lip, tilt the mask
up.

10 If you feel air leaks around the cushion,

reposition the mask on your face to
achieve a better seal.
Take time to adjust all straps and the
position of the mask so that you can
achieve a secure and comfortable fit.

Notes:

• If you are unable to resolve any leaks you

may need to try another cushion size.

• Excess headgear length may be trimmed

to a suitable length if required. Leave at
least 30 mm free length on the straps.

• Select "Standard" as the mask option

when using the M

IRAGE KIDSTA with

ResMed flow generators that have mask
setting options.

REMOVING THE MASK

To remove the MIRAGE KIDSTA, squeeze
one of the headgear clips. This releases one
side of the headgear from the mask. Pull the
mask and headgear away from your head.

Notes:

• Do not pull the headgear off your head

without releasing the headgear clips first.

• You can detach the elbow from the mask

frame while wearing the mask. This is
useful when therapy needs to be stopped
for a short time; for example if you need to
go to the bathroom.

• Check that you can remove the headgear

clip, the quick release swivel or the
headgear unaided.

DISASSEMBLING FOR CLEANING

See Figure D.
1 Detach the mask elbow. To do this,

squeeze the sides of the mask elbow at
the finger grips while pulling it away from
the mask frame (Fig. D-1).

2 Disconnect and separate the main air

tubing, short air tubing, mask elbow and
vent cover (Fig. D-2).

Notes:

• To prevent damage to the short air

tubing, disconnect it by holding it at the
cuff.

• The swivel does not need to be

disconnected from the short air tubing.

3 Detach the headgear from the mask

frame by squeezing and releasing both
headgear clips.

4 Remove the ports cap from the mask

frame (Fig. D-3).

5 Firmly pull the mask cushion away from

the mask frame (Fig. D-4).

ENGLISH

Notes:

• Wash the headgear before first time use,

as the dye may run. It is important to
always handwash the headgear.

• The headgear may be washed without

being disassembled.

DAILY/AFTER EACH USE

Handwash the mask components in
lukewarm, soapy water. Use pure soap
(an example of pure soap is Dove®soap,
unscented; made by Unilever). Rinse the
components well and allow them to air dry
out of direct sunlight.

WEEKLY

Handwash the headgear in warm, soapy
water. Use pure soap. Rinse well and allow
it to air dry out of direct sunlight.

. CAUTIONS

• Do not use solutions containing

bleach, chlorine, alcohol, aromatics,
moisturisers, antibacterial agents, or
scented oils to clean any part of the
mask system or air tubing. These
solutions may cause damage and
reduce the life of the product.

• Do not expose any part of the mask

system or tubing to direct sunlight as
it may deteriorate.

• If any visible deterioration of a mask

component is apparent (cracking,
crazing, tears etc), the mask
component should be discarded and
replaced.

CLEANING THE MASK BETWEEN

ATIENTS

P

The mask system (excluding the swivel and
short tube) is validated for multipatient use.
Clinicians should refer to the Masks
Disinfection/Sterilisation Guide for details.

To clean the headgear between patients,
use the method described in the previous
section “Cleaning the Mask in the Home”.

REASSEMBLING THE MASK

See Figure E.
1 Insert the mask cushion into the groove

of the mask frame (Fig. E-1). Fit the top
section first and then work your way
around, pushing the mask cushion into
the mask frame.

Note: The diamond markers on the mask

frame and on the mask cushion (one on
top, two at the bottom) must line up.

2 Push the ports cap onto the mask ports

(Fig. E-2).

3 Attach the vent cover to the mask

elbow. To do this, insert the elbow into
the ring of the vent cover (Fig. E-3).
Push the ring to the top so that the vent
cover is over the back of the elbow.
Then, press the lip of the vent cover to
ensure that it is securely seated in the
groove of the elbow.

4 Connect the short air tubing to the mask

elbow.

5 Connect the swivel to the main air

tubing, ready for next use (Fig. E-4).

ADDITIONAL INFORMATION

REASSEMBLING THE HEADGEAR

Note: You do not need to disassemble the
