Abstract:The thermoresistance of various lots of two biological indicators (Bls) for steam sterilization control, a Scandinavian BI (SBI) and the Attestg̊ BI (ABI), were compared during sterilization cycles in a hospital prevacuum (pressure‐pulsing) steam autoclave at 134°C, saturated steam. ABI No. 1242, ABI No. 1262 (its replacement) and incremental heat exposure times between 0 s and 180 s were used. The intrachamber temperature and pressure were continuously measured and monitored throughout the sterilizatio… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
