Decontamination第 3 / 100 题
What air pressure relationship should the decontamination area have compared with adjacent areas of the department?
a.Positive pressure, so clean air is pushed toward the soiled workroom
b.Equal pressure, so no air movement occurs between rooms
c.Negative pressure, so contaminated air does not flow into clean areas
d.Alternating pressure controlled by the sterilizer cycle
解析
The decontamination room is held at negative pressure so airborne contaminants and aerosols generated during cleaning are drawn out and exhausted rather than escaping into preparation, packaging, or sterile storage. Positive pressure is used in the clean workroom and sterile storage. Equal or alternating pressure would allow uncontrolled migration of contaminated air.
