IAHCSMM CRCST Practice Test – Chapter 14 (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. The SFPP Sterilizers operate through a repeated sequence of steam flushes and pressure pulses to remove air from the sterilizing chamber, which allows for the sterilization of materials without the need for 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 special 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, air is displaced as steam enters the sterilizer, leading to an increase in pressure and temperature. During exposure, the sterilizer’s control system begins timing the exposure phase once the desired temperature is reached.
