What is an adequate routine for disinfecting cup electrodes after removing adhesive residue and washing?

Soaking cup electrodes in a 1:10 bleach and water solution for 10 minutes is an effective disinfection method because bleach is a powerful disinfectant that can effectively kill a wide range of pathogens, including bacteria, viruses, and fungi. This concentration of bleach is recognized as a suitable dilution for general disinfection purposes in healthcare settings, ensuring that the electrodes are properly sanitized before being reused.

This method is especially crucial in polysomnography, where maintaining a sterile environment helps prevent cross-contamination between patients. The contact time of 10 minutes is sufficient to ensure that any harmful microorganisms present on the electrodes are effectively eradicated, making it a safe practice for patient care.

Other methods, while they may have some level of efficacy, do not match the thoroughness of bleach soaking. For example, mere soaking in alcohol may not achieve the desired level of disinfection for certain pathogens, while boiling can be impractical and may damage the electrodes. Disinfectant wipes could also fail to provide adequate contact time or coverage for complete disinfection, particularly compared to a soaking method.
