Inspection
Inspect and if required, repeat the cleaning steps until visually clean. Shake air tubing to remove excess
water.
Drying
Allow the components to dry out of direct sunlight.
Note: Drying is not required after cleaning if thermal disinfection is continued immediately.
Potable water with a hardness ≤ 150 mg/L is recommended for all cleaning, disinfection and rinsing
1
steps. .
Disinfection
In the following procedures, only one disinfection process needs to be performed: Thermal disinfection
OR Chemical disinfection.
High level thermal disinfection
1. Immerse the components in a water
air bubbles are trapped.
2. Soak the components in a hot water bath. ResMed has validated:
• Water bath: at 167ºF (75ºC) for 30 minutes
Note: Higher temperatures may damage the components.
3. Allow the components to dry out of direct sunlight.
OR
High level chemical disinfection
1. Make a solution of CIDEX OPA (Ortho-phthalaldehyde 0.55%) as directed by the disinfectant
manufacturer. ResMed has validated:
• CIDEX OPA at 69.8ºF to 77ºF (21ºC to 25ºC)
2. Soak the components in the solution at room temperature (approximately 69.8ºF to 77ºF (21ºC to
25ºC) for 12 minutes. Agitate the components in the disinfection solution to ensure there are no air
bubbles.
3. Rinse and agitate the components in water
Shake air tubing to remove excess water.
4. Repeat the rinse procedure two additional times using fresh water
5. Allow the components to dry out of direct sunlight.
Potable water with a hardness ≤ 150 mg/L is recommended for all cleaning, disinfection and rinsing

steps.
Inspection
Perform a visual inspection of each component.If any visible deterioration is apparent (holes, tears or
cracks etc) replace the component.

bath. Agitate the components in the water bath to ensure no
5 liters per component at ≤ 140ºF (≤60ºC) for 1 minute.
