Sterilisation
Recommended guidelines for sterilisation
CAUTION
To prevent possible damage to components, peak sterilisation
temperatures must not exceed :
54
o
C (130
o
F) for gas (ethylene oxide) or,
134
o
C (275
o
F) for steam autoclave.
Low temperature autoclave is 121
o
C
Do not sterilise the ventilator control unit. The internal
components are not compatible with sterilisation techniques and
may be damaged.
Following sterilisation with ethylene oxide, components must be
quarantined in a well ventilated area to allow dissipation of any
residual gases.
Follow the recommendations given by the steriliser
manufacturer for aeration periods required.

NOTE
1. Liquid method indicates the use of a high level
disinfectant.
2. Examples of suitable high level disinfection liquid agents
are: Nu-Cidex, Sporicidin, and Sonacide.
3. The exhalation diaphragm valve must be removed,
cleaned and sterilised separately.
