What classification system did the AEA create for the degrees of contamination on instruments?

The classification system created by the AEA (American Electrology Association) for the degrees of contamination on instruments is based on three categories: Critical, Semi-Critical, and Non-Critical. This system is crucial in determining the appropriate level of disinfection and sterilization required for different types of instruments used in electrology.

Critical items are those that enter sterile tissues or the vascular system. Therefore, they must be sterile to prevent infection and must undergo rigorous sterilization processes. Semi-critical items contact mucous membranes or non-intact skin. These require high-level disinfection but do not necessarily need to be sterile, as they do not penetrate sterile sites. Non-critical items only come into contact with intact skin, which necessitates cleaning and low-level disinfection but not the stringent measures required for the other classifications.

Understanding this classification helps practitioners maintain high standards of infection control and safety in their practices, ensuring patient safety and compliance with health regulations.
