As more students determine that a job in sterile processing is one of the best choices as a career, its job description is fundamental and explicit.Ensuring that all equipment and tools are safe during surgical procedures is just one thing that must be regularly remembered, especially in studying an online sterile processing technician course.

Before enrolling in the top online sterile processing course, familiarizing the following medical jargon will be crucial in preserving the medical equipment supply chain and getting that SPT certification.This will also help eradicatethe infection in hospitals, clinics, and surgery centers.


This is how many live microbes there are on an item that has been infected. Microbial loads and bio loads are other names for it. Microorganisms discovered on goods, tools, equipment, and packaging are calledbioburden.

The most crucial procedures in decontaminating all reusable medical equipment are thorough cleaning and rinsing. Instead of eradicating bacteria, this removes bioburden and is followed by disinfection or sterilization.

Chemical Indicator

Chemical indicators are one of the most crucial tools for sterilization monitoring. They may retaliate in one or more of the physical conditions in the sterilizing chamber to a specific chemical or material alteration. Potential sterilizing issues can be quickly identified using chemical markers. They could result from poor loading, improper packaging, or sterilizer faults.


Decontamination is a procedure or treatment used to secure a medical device or instrument enough to use or handled. OSHA defines decontamination as “the use or combination of chemical or physical techniques to remove, activate, or destroy bloodborne pathogens from a surface or object where they are no longer capable of spreading infectious particles.”

Ethylene Oxide Sterilization

Instruments and gadgets susceptible to heat and humidity can be sterilized using ethylene oxide. ETO is a gas that is colorless, explosive, and flammable. The operating ranges are the name given to these four factors. These contain the following: exposure time, relative humidity, temperature, and gas concentration (450-1200 mg/l, 37-63degC) (from 1 to 6 hours). These variables influence the effectiveness of ETO sterilization. The time needed to sterilize can be shortened by lowering the temperature or gas concentration.
