air removal test
Daily test procedure to verify proper air evacuation from steam sterilizer chambers before processing loads.
Full Definition
An air removal test is a mandatory daily test performed on prevacuum and pulsing prevacuum steam sterilizers to verify that the vacuum system effectively removes air from the sterilization chamber. Residual air in the chamber can create cold spots that prevent steam penetration and compromise sterilization efficacy. The test typically uses a standardized test pack with chemical indicators or electronic monitoring devices. Failure of the air removal test requires immediate sterilizer investigation and repair before processing any loads intended for patient use.
Usage
