Soak the reusable mask components in a
commercially available solution of glutaraldehyde
3.4% (eg CIDEX Plus

), peracetic acid 0.08%
(eg CIDEX PA
®
) or orthopthalaldehyde 0.55%
(eg CIDEX OPA

) as described in the
manufacturer’s instructions.
b
Rinse the mask components as described in the
manufacturer’s instructions and allow them to
air dry out of direct sunlight.
c
Perform a visual inspection of each mask
component. If any visible deterioration of a mask
component is apparent (eg cracking, tears etc),
the mask component should be discarded and
replaced. Yellow discolouration of the cushion
may occur. This discolouration is acceptable.
Testing by ResMed has shown that the mask
components can withstand 15 cycles using
solutions of glutaraldehyde 3.4% (eg CIDEX Plus
®
),
peracetic acid 0.08% (eg CIDEX PA
®
) or
orthopthalaldehyde 0.55% (eg CIDEX OPA
