In the Spaulding Classification, what defines semi-critical devices?

• A. Devices that do not contact any body tissues
• B. Devices that contact intact skin only
• C. Devices that come in contact with nonintact skin or mucous membranes
• D. Devices that are used for invasive procedures

Answer: (C)

In the Spaulding Classification, semi-critical devices are characterized by their contact with nonintact skin or mucous membranes. This classification is essential for determining the appropriate level of disinfection required for different types of medical equipment. Semi-critical devices, since they come into contact with surfaces that may harbor pathogens but do not penetrate sterile tissue, necessitate a higher level of disinfection than non-critical devices, which merely contact intact skin or are completely non-contact.

By recognizing that semi-critical devices play a role in procedures where there is a potential risk of infection through mucous membranes or damaged skin, it becomes clear why they require specific handling and disinfection protocols. This understanding informs practices in infection control and assists healthcare professionals in ensuring the safety and efficacy of medical instruments and devices.
