HSPA Sterilization Methods and Monitoring 2

Question 1

What are the standard parameters for prevacuum steam sterilization of wrapped instruments?

Accepted Answer

132°C (270°F) for 4 minutes exposure

Answer

Prevacuum cycles operate at 132°C with 4 minutes minimum exposure for wrapped non-porous items.

Question 2

What is the purpose of a process challenge device (PCD)?

Accepted Answer

To create defined resistance simulating the most challenging items, providing rigorous testing of sterilization

Answer

A PCD creates a standardized challenge at least as difficult as the most challenging items in the load.

Question 3

How do Class 6 emulating indicators differ from Class 5 integrating indicators?

Accepted Answer

Class 6 responds to one specific cycle; Class 5 responds across a range of cycle types and correlates with BI performance

Answer

Class 6 is cycle-specific; Class 5 works across multiple cycle types and correlates with biological indicator kill.

Question 4

What records must be maintained for each sterilization cycle?

Accepted Answer

Complete documentation including date, time, sterilizer ID, cycle number, load contents, physical parameters, operator, and monitoring results

Answer

Every cycle must have complete documentation creating an audit trail for quality assurance and recall tracing.

Question 5

What is the significance of the drying phase in steam sterilization?

Accepted Answer

Wet packages allow microbial migration through packaging, compromising sterility

Answer

Residual moisture creates a pathway for microorganisms to wick through packaging (strike-through).
