PCD
Pronunciation: P-C-D
Also written as: PCD — Process Challenge Device
Process Challenge Device - a test system designed to verify sterilization process efficacy in difficult-to-sterilize configurations.
Full Definition
A Process Challenge Device (PCD) is a standardized test system that presents a greater challenge to sterilization than the routine load being processed. PCDs typically contain biological or chemical indicators placed in configurations that simulate worst-case sterilization conditions, such as within lumened instruments or densely packed areas. These devices are used to validate sterilization processes and monitor routine performance to ensure that all items in a load achieve sterility assurance.
Usage
Usage note: Always specify PCD composition and placement in validation documentation.
In Context
- "The sterilization cycle validation required PCD testing at three different load positions." — Validation protocol
- "Daily PCD monitoring detected a steam penetration issue in the autoclave chamber." — Quality assurance log
