What are the two types of air pressure utilized in the Central Sterile Department?

The two types of air pressure utilized in the Central Sterile Department are positive and negative air pressure. This distinction is critical for maintaining a sterile environment and preventing contamination.

Positive air pressure is used in areas such as sterile storage and in certain surgical suites. This means that air pressure is maintained at a higher level compared to the outside environment. The primary goal is to prevent unsterilized air and contaminants from entering these areas, thus protecting the integrity of sterile instruments and supplies.

Negative air pressure, on the other hand, is utilized in areas such as decontamination or certain processing areas. In this setting, the air pressure is lower than that of adjacent areas, which helps to ensure that contaminated air is not released into the surrounding environment. It effectively contains particles, aerosols, and microorganisms, helping to protect both staff and other areas of the facility.

The other options do not accurately capture the critical air pressure types relevant to sterile processing environments, making them less applicable in the context of maintaining sterile conditions in a Central Sterile Department.
