Three Kinds of Monitoring
Captions available
The idea
Sterilization is monitored with three kinds of indicators used together: mechanical, chemical and biological.
In practice
Mechanical monitors record the cycle's conditions, chemical indicators show exposure to the process, and biological indicators test whether the process actually killed resistant spores.
Where people slip
No single indicator proves sterility on its own; the three are read together.
