IAHCSMM CRCST Practice Test – Chapter 14 High-Temperature Sterilization

Last Updated on August 5, 2024

HSPA [Formerly IAHCSMM] CRCST Practice Test – Chapter 14 High-Temperature Sterilization(Certified Registered Central Service Technician) Practice Test. Chapter 14 of the CRCST Practice Test provides an in-depth understanding of various sterilization processes used in healthcare facilities.

It particularly focuses on Steam Flush Pressure Pulse Sterilizers (SFPP) and Immediate-Use Steam Sterilizers. SFPP Sterilizers operate through a repeated sequence of steam flushes and pressure pulses to remove air from the sterilizing chamber, allowing materials to be sterilized without needing a vacuum.

The chapter also delves into the use of Immediate-Use Steam Sterilizers, often located in operating rooms or surgical suites, labor and delivery units, and particular procedure areas. These are primarily used for emergency sterilization of instruments when time does not allow for terminal sterilization.

Furthermore, this chapter explains the different stages of the saturated steam sterilization cycle, which typically include conditioning, exposure, exhaust, and possibly drying. In the conditioning phase, the air is displaced as steam enters the sterilizer, increasing pressure and temperature. During exposure, the sterilizer’s control system begins timing the exposure phase once the desired temperature is reached.
