If you use an electrolyte spray, this liquid may be diluted with equal amounts of distilled
water, if desired. This reduces the amount of build-up on the electrodes yet usually
provides adequate moistening of the electrodes.
NOTE: As you increase the intensity to higher levels during setup, if your patient feels a
“biting” sensation or if the patient feels nothing, this indicates you are not getting
adequate conductivity—the electrode may be too dry or is not moistened evenly across its
entire surface. Stop the setup and correct the problem.
2. Carbon electrodes must be free from any build-up. If electrodes have a build-up from
body oils or a moistening agent such as an electrolyte spray, conductivity is greatly
impaired. If treatment is allowed to continue, intensity could be inhibited. When using
carbon electrodes with any electrotherapy device, you must make sure conductivity is not
impaired due to any type of build-up on the electrodes.
3. 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 your carbon electrodes are showing wear, you can send them to Dynatronics to
be tested with an ohm meter. Good carbon electrodes should test at between 40 and 200
ohms. Unfortunately, practitioners frequently send us electrodes having resistance measuring
in the thousands of ohms! Overused electrodes such as this present a potential hazard to the
patient.
How to Clean Carbon Electrodes. Carbon electrodes from Dynatronics may be cleaned
using a mild soap and a small brush (such as a nail brush). They may also be sterilized in an
Autoclave. Daily cleaning is recommended.
Self-Adhesive Electrodes
Dynatronics’ “Polys” self-adhesive electrodes are intended for multiple usage when used
appropriately. 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 clean and free from oils or
flakiness.
