Full Definition
Non-critical instruments are medical devices classified under the Spaulding system that come into contact with intact skin only and pose the lowest risk of transmitting infection. These instruments require cleaning and low-level disinfection but do not require sterilization. Examples include stethoscopes, blood pressure cuffs, and some external monitoring devices. Proper classification is essential for determining appropriate reprocessing requirements and ensuring cost-effective resource allocation while maintaining patient safety standards.
