Giải thích
A PCD, such as a commercial test pack or a homemade AAMI test pack, places the indicator in the hardest-to-sterilize location so that a passing result gives confidence that easier items were also processed. The design must challenge the process at least as much as the routine load. Pressure verification, training, and electronic record keeping are separate functions unrelated to the definition of a PCD.
