WARNING
It is contra-indicated to clean the double circuit expiratory valve in an automatic washing
machine due to the risk of damaging its integrated flow measurement system.

Cold disinfection protocol
ResMed recommends the disinfection of the double circuit expiratory valve according to the
following protocol. This protocol allows cleaning, pre-disinfection, and complete cold disinfection
through two cycles. Proceed as follows:
1. Disassemble the expiratory valve and throw away the valve clapper.
2. Disinfection Cycle A (using a pre-disinfecting cleaning solution: HEXANIOS G+R or
Salvanios pH 7):
•
Immerse all parts (except the clapper) for 15 minutes in the pre-disinfecting detergent, i.e.
HEXANIOS G+R diluted to 0.5%, or Salvanios pH 7 diluted to 0.5%.
•
During immersion, gently remove any visible dirt with a soft brush.
•
Rinse under running water.
•
Dry on a paper towel.
3. Disinfection Cycle B (using ANIOXYDE 1000, a high-performance disinfecting solution):
•
Immerse fully for 30 minutes in the activated, high-performance disinfecting solution
ANIOXYDE 1000.
•
Rinse under running water.
•
Dry on a paper towel.
4. Reassemble the expiratory valve using a new valve clapper.
Note: After the twentieth cycle, fine whitish lines may appear on the valve. These will not affect
its performance in any way.
CAUTION
Do not use a high-pressure air generator to dry the valve more rapidly as this would
damage its honeycomb structure.
Autoclaving
If required by your hospital protocol, the expiratory valve can be sterilised by autoclave. Prior to
autoclaving, the valve must be dismantled and cleaned in a detergent bath. Proceed as follows:
1. Disassemble the expiratory valve and throw away the valve clapper.
2. To clean:
•
Immerse all parts (except the clapper) for 15 minutes in the pre-disinfecting detergent,
i.e. HEXANIOS G+R diluted to 0.5%, or Salvanios pH 7 diluted to 0.5%.
•
During immersion, gently remove any visible dirt with a soft brush.
•
Rinse under running water.
•
Dry on a paper towel.
3. To autoclave:
•
Put the disassembled parts of the expiratory valve in an autoclave at a temperature of
134°C (273°F) for 18 minutes.
4. Reassemble the expiratory valve using a new valve clapper.
Note: After the twentieth cycle, fine whitish lines may appear on the valve. These will not affect
its performance in any way.
