4.1.6 Patient Airway Flow Sensor
The flow sensor can be hand or machine washed and disinfected with a suitable disinfectant.
Steam autoclaving
must not exceed 134 o C. The sensor can be sterilised with ethylene oxide.
To clean the flow sensor, pour distilled water slowly and gently into the outlet port. Water must
not be directed into this port under pressure.
Chemical decontaminants or liquid sterilisation agents will damage the sensor
and must NOT be used for cleaning or sterilising. If autoclaving the sensor, the
autoclave must only be used with distilled water.
4.1.7 Blanking cap on patient flow sensor is NOT autoclavable.
Bellows
Only the bellows base and the parts inside the bellows require sterilisation.
To avoid damage to the equipment:
Peak sterilisation temperature must not exceed 134ºC.
Do not sterilise the control unit.
Gas sterilisation should be followed by quarantine in a well-ventilated area to
allow dissipation of residual absorbed gas.
Follow the sterilisation agent manufacturer's instructions.
The expiratory valve must be disassembled prior to autoclaving to prevent the
occurrence of clamping stresses.
The paediatric adapter, can be sterilised but must not be autoclaved.
1. Pull absorber forward to disconnect the bellows base.
2. Loosen the two thumb screws retaining the bellows base and remove the bellows base
and housing from the control unit.
3. Remove the pop-off valve and paediatric bellows adapter (if fitted) and clean and sterilise
them separately.
4. Perform sterilisation as specified in the table opposite.
