Aeration After Ethylene Oxide
Captions available
The idea
Items sterilized with ethylene oxide absorb some of the gas and must be aerated before use.
In practice
Mechanical aeration takes many hours at raised temperature; room aeration takes days; many modern sterilizers aerate in the same chamber.
Where people slip
An item released before aeration is complete carries toxic residue to the patient and the staff.
