SterilizationCâu 30 / 100
A wrapped instrument set is being sterilized in a dynamic-air-removal steam sterilizer at 270 degrees F (132 degrees C). What is the typical minimum exposure time?
a.1 minute
b.4 minutes
c.15 minutes
d.30 minutes
Giải thích
Four minutes at 270 degrees F is the commonly validated exposure time for wrapped goods in a dynamic-air-removal cycle because air is removed before the exposure phase begins. Fifteen minutes at 270 degrees F and thirty minutes at 250 degrees F are gravity cycle parameters, which take longer because air removal is passive. One minute is not a validated exposure time for any wrapped steam cycle, and the device manufacturer instructions always govern the final selection.
