After disassembly, thoroughly disinfect or sterilize the mask components by
following the procedure for one of these methods:
• Chemical Disinfection
• Thermal Disinfection
• STERRAD
™
Sterilization.
Option 1: Chemical Disinfection
Pre-disinfection
1 Disassemble the mask.
2 Clean the individual parts of the mask with a soft bristle brush for one
minute while soaking them in detergent (eg, Aniosyme
™
DDI or Alconox
™
).
Pay particular attention to all crevices and cavities.
3 Rinse the components twice by agitating them vigorously in drinking quality
water (5 litres per mask) and allow them to air dry out of direct sunlight.
ResMed has tested the detergents Aniosyme DDI (diluted at 0.5% for 15
minutes) and Alconox (diluted at 1%).
Disinfection
1 Soak the disinfectable mask components in a commercially available
solution of peracetic acid 0.15% (eg, Anioxyde
™
1000),
ortho-phthalaldehyde 0.55% (eg, CIDEX
™
OPA) or glutaraldehyde 3.4%
(eg, CIDEX Plus
™
).
2 Rinse the mask components in drinking quality water (5 litres per mask) and
allow them to air dry out of direct sunlight.
Testing by ResMed has shown that the mask components can withstand 15
cycles using solutions of peracetic acid (0.15% Anioxyde 1000 for 30 minutes),
ortho-phthalaldehyde (0.55% CIDEX OPA for 20 minutes) or glutaraldehyde
(3.4% CIDEX Plus for 20 minutes).
Note: If using the detergents and disinfectants listed above, the following
combinations should be followed:
• Detergent Aniosyme DDI with Anioxyde 1000 as the disinfectant
OR
• Detergent Alconox with disinfectant CIDEX OPA or CIDEX Plus.
