4. Carbon electrodes eventually wear out.
Do not assume you can safely use carbon electrodes indefinitely. Over time these electrodes will wear; and when worn,
the amount of current delivered through the electrode will decrease and will be inconsistent over the surface of the
electrode. As a general rule, carbon electrodes that are used regularly should be replaced at least every six months.
Do not take chances with patient safety!
Discard worn carbon electrodes!
If you think that your carbon electrodes are showing wear, you can test them with an ohm meter. Good carbon electrodes
should measure resistance between 40 and 200 ohms.
Self-Adhesive Electrodes
Dynatronics’ self-adhesive electrodes are intended for multiple but patient specific use due to the danger of cross
contamination. Improper use of the electrodes can decrease the life of the electrode and could even result in harm to your
patient. The following instructions will help you achieve maximum usage from your electrodes while ensuring patient safety
and comfort during treatment.
1. Make sure the electrode is adhering and making contact with the skin across the entire surface of the electrode.
Electrodes will lose their adhesive quality when exposed to air, dust, dry skin, etc.
To Retain Adhesiveness:
• Electrodes should be stored in a tightly sealed pouch until used.
• The patient’s skin should be thoroughly cleaned and free from oils or flakiness prior to placing the electrodes.
To Restore Adhesiveness:
• Before a Treatment. Before placing the electrode on the patient, moisten the patient’s skin with a damp cloth
using plain water, then apply the electrode to the skin.
• After a Treatment. Apply one or two drops of water to the adhesive side of the electrode using plain water, rub
it lightly with fingertips, reapply the electrode to its plastic backing, and seal it tightly in its storage pouch. Do
not use an electrolyte spray to remoisten self-adhesive electrodes as this substance can destroy the adhesive.
Self-adhesive electrodes do not require sterilization.
• With this method of re-hydration, after a couple of hours electrodes can regain up to 90 per cent of their original
adhesive quality.
2. NEVER use a self-adhesive electrode for more than 15 treatments (maximum).
3. NEVER USE STRAPS, WEIGHTS, or other devices to attach self-adhesive electrodes to the skin. If an electrode
has lost its adhesive quality, you can use one of the methods given above to re-hydrate the adhesive, or you should
