Recommendations from the American Clinical Neurophysiology Society and an ASET webinar say that single-use EEG cup electrodes reduce the risk of infections in general, reports Neurology Insights.

It is important to note here that single-use cup electrodes cannot be cleaned and used again like those designed to be reused. Reusables are made of metal and coated with gold, while single-use electrodes are molded out of plastic and coated with silver/silver chloride.

“If you clean the single-use electrodes, you will wash off the coating and there will be degradation of the signal. You are not supposed to even rinse them,” says Brett Alpaugh, senior marketing manager for neurology products at Ambu Inc.
