CBSPD Sterile Processing Technician Test 2025 – 400 Free Practice Questions to Pass the Exam

The three essential parameters of steam sterilization are steam under pressure, time, and temperature.

Steam sterilization is a widely used method for sterilizing medical instruments and equipment, and it operates on the principle that moist heat is more effective at killing microorganisms than dry heat. When steam is produced under pressure, it allows for higher temperatures to be achieved, which effectively denatures proteins and destroys microbial cells.

The duration of exposure, or time, is critical because it ensures that all microorganisms within the load reach the proper temperature for a sufficient period to ensure effective sterilization. Simply having the correct temperature is not enough; if the exposure time is too short, sterilization might not be achieved.

Therefore, the combination of high temperature, sufficient time, and steam under pressure creates the ideal conditions for effective sterilization, allowing for the killing of even the most resistant spores and pathogens. Understanding these parameters is crucial for sterile processing technicians to ensure proper sterilization practices and maintain patient safety in healthcare settings.
