Infection ControlCâu 68 / 100
Which set of parameters describes a typical steam autoclave cycle for wrapped instruments?
a.160°F for 5 minutes at atmospheric pressure
b.About 250°F (121°C) at 15 psi for roughly 15 to 30 minutes
c.350°F for 3 minutes with no pressure
d.212°F for 60 minutes in an open water bath
Giải thích
A standard gravity steam cycle for wrapped instruments runs at approximately 250°F (121°C) under 15 psi for about 15 to 30 minutes, and pressure is what raises steam above the boiling point. A cycle at 160°F would not kill spores. Dry heat sterilizers reach around 320°F to 375°F but need pressure-free chambers and longer times, and boiling water at 212°F does not sterilize.
