Decontaminating
Before the disinfection process, each component must be cleaned and rinsed so no visible contamination is
present.
1. Clean all components with a soft bristle brush for one minute while soaking them in the detergent
solution. Pay particular attention to all crevices and cavities.
2. Thoroughly rinse each component according to the manufacturer’s instructions.
ResMed has tested the following detergents according to the manufacturer’s instructions:
Detergent Water temperature
Alconox™ Tergazyme
(diluted at 1%)
Hot water (approx 60°C)
Warm water (approx 50°C)
Aniosyme™ DDI
(diluted at 0.5%)
Room temperature water (approx 20°C)
Neodisher MediZym™
(diluted at 2.0%)
Warm water (approx 45°C)
Disinfecting
In the procedures below, only one disinfection or sterilization procedure needs to be performed:
• High level thermal disinfection
• High level chemical disinfection
• Sterilization.
High level thermal disinfection
1. Soak the disassembled components in a hot water bath at 90°C for 1 minute. Take care that no air
bubbles are trapped against the components.
2. Air dry out of direct sunlight.
