Disinfection Guide
Preparing the device for use between patients
When the device is used for multiple patients, for example, in a sleep lab, clinic, hospital or at a health
care provider, the outlet connector, air tubing , cleanable humidifier tub and device enclosure should be
reprocessed between each patient.
Described here are ResMed's recommended and validated procedures for cleaning and disinfecting the
outlet connector, air tubing, cleanable humidifier tub and device enclosure. The person executing
reprocessing activities is responsible for ensuring that reprocessing is completed in line with ResMed's
validated procedures. Components not identified in the reprocessing instructions do not require
reprocessing or are intended for single patient use.
Note: The standard HumidAir 11 tub cannot be reprocessed.
WARNING
•Always follow cleaning and disinfection instructions. Some cleaning products may damage
the components and their function or leave harmful residual vapors.
•Any deviations from the procedures or claimed maximum number of cycles in this guide can
have an adverse effect on the components and consequently the safety or the quality of
therapy.
•When using detergents, disinfectants or equipment, always follow the instructions provided
by the manufacturer of those products. In the event of conflict, this guide takes precedence.
•Always follow safe operating practices, including the use of appropriate Personal Protective
Equipment (PPE), as required. Refer to the instructions provided by the manufacturer of those
products for more details.
•Beware of electrocution:
•Do not immerse the device, AC Adaptor or power cord in water.
•Do not connect to power while the device is wet. Make sure that all parts are dry before plugging
it in.

Disassembling
Before disassembly, turn off the device and ensure the AC adaptor has been removed.
Cleanable Humidifier tub
1. Hold the humidifier tub at the top and bottom, press it gently and pull it away from the device.
Note: take care when handling the humidifier tub as the humidifier tub may be hot. Allow 10
minutes for the heater plate and any excess water to cool.
2. Hold the base of the humidifier tub and fully open the humidifier tub lid and pull it away so that it
easily detaches from the base.

3
Air tubing
1. Pinch the cuff of the air tubing, and gently pull it away from the device.
2. Hold both the cuff of the air tubing and the swivel of the mask, then gently pull apart.
Outlet connector
1. Locate the outlet connector on the inside of the device and release it by pressing the clip firmly.
2. Remove the outlet connector by pulling it out through the outlet connector socket at the rear of the
device.

Device enclosure
Cleaning
Clean the device enclosure using an alcohol based cleaning and disinfection wipe. ResMed has
validated CaviWipes1.
1. Wipe the exterior of the device using a wipe until visually clean following the manufacturer's
instruction for cleaning. Use a minimum of two wipes.
If visual debris is still present, perform the following:
2. Clean the exterior of the device with a dry, soft bristle brush and wipe the exterior of the device
using a new cleaning and disinfection wipe following the manufacturer's instruction for cleaning.
Disinfection
Repeat the first step with a new wipe and follow the manufacturer's instructions for disinfection.
Note: Failure to clean the component as indicated may result in inadequate disinfection.
Drying
Allow sufficient time for the device to air dry completely.
Note: Drying is not required after cleaning if disinfection is continued immediately.
Inspection
Perform a visual inspection of the device casing. If any visible deterioration is apparent (cracking,
crazing etc) discontinue use and contact your care provider or your ResMed Service Centre.
Air tubing, outlet connector and HumidAir 11 tub
Cleaning
1. Make a solution of a mild alkaline anionic detergent and water1as directed by the manufacturer's
instructions. ResMed has validated:
•Alconox at 1% (10 g/L) in water1at 69.8ºF to 131ºF (21ºC to 55ºC)
2. Soak all components for 5-10 minutes. Agitate the component in the cleaning solution to ensure
there are no air bubbles.
3. Clean the inside and outside of all components with a soft bristle brush while soaking in a detergent
solution. Pay particular attention to all crevices and cavities.
•Tubing (Standard, SlimLine and ClimateLineAir 11): 3 minutes of brushing
Note: A soft bristle tube/bottle brush is required to clean the inside of the tubing. Remove tubes
from the detergent solution to assist brushing.
•Outlet connector: 1 minute of brushing
•HumidAir 11 Cleanable tub: 2 minutes of brushing
4. Thoroughly rinse each component as follows: in 5 liters of water1at ≤140ºF (≤60ºC) for each
component by immersing it. Rinse tubing for 30-60 seconds. Agitate the component in the rinsing
water to ensure there are no air bubbles.
5. Repeat the rinse procedure two additional times using fresh water1for a total of three rinses.
Note: Failure to clean the component as indicated may result in inadequate disinfection.

5
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.
1Potable water with a hardness ≤150 mg/L is recommended for all cleaning, disinfection and rinsing
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 water1 bath. Agitate the components in the water bath to ensure no
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 water15 liters per component at ≤140ºF (≤60ºC) for 1 minute.
Shake air tubing to remove excess water.
4. Repeat the rinse procedure two additional times using fresh water1for a total of three rinses.
5. Allow the components to dry out of direct sunlight.
1Potable water with a hardness ≤150 mg/L is recommended for all cleaning, disinfection and rinsing
steps.
Inspection
