What should be avoided when preparing skin for electrode application?

When preparing skin for electrode application, using an alcohol pad should be avoided due to the potential for skin irritation and the impact it can have on the adhesion of the electrodes. Alcohol can cause the skin to become too dry, which might interfere with the effective adhesion of the electrodes and lead to discomfort for the patient. It’s important to ensure that the skin is clean and prepared for optimal contact, but the method of cleansing is crucial; alcohol might not be the best choice for all patients depending on their skin type and sensitivity.

Other methods of skin preparation, such as clipping hair, cleansing with soap and water, and gently rubbing the area with a gauze, are acceptable practices as they focus on ensuring that the skin is clean and free of obstructions for optimal electrode function. Clipping hair can help prevent interference from hair, while proper cleansing removes dirt and oils that could hinder the signal. Gently rubbing with gauze can help ensure that the surface is smooth and ready for the electrode application.
