THEORY OF OPERATION
The I-Bresis™ Iontophoresis System operates on the physical principle that electrically like-charges repel each other. A
positively charged substance is forced away from a positively charged electrode. A negatively charged substance is forced
away from a negatively charged electrode. When the Patch pads are filled with ionic saline or drug solutions and the Patch is
attached to the patient’s skin, current begins flowing. The ionic solutions are forced into the skin away from the like-charged
electrode. The dosage of ionic drug solution delivered depends on the current applied and the length of time for which the
current is applied. Dosage is expressed in units of mA min (milliAmpere minutes) and is calculated by multiplying the current
(mA) by the time (min).
PREPARING THE PATIENT
Advise the patient that iontophoresis has the potential to result in skin irritation and/or burns.
• Direct current may result in transient erythema under the pads. The erythema generally resolves itself within a few hours.
• Use caution when treating patients with sensitive skin or those who may have difficulty healing.
1.
Advise the patient that iontophoresis causes mild tingling, prickling and/or a warm sensation. This is normal and should
be anticipated by the patient.
2.
Advise the patient to report immediately any pain during treatment. If the patient complains of pain, pause the treatment,
inspect the area under the Patch and make any necessary adjustments (e.g., reposition the Patch to ensure full skin
contact, decrease current, etc.) before resuming the treatment, or discontinue the treatment.
3.
Advise the patient to remove any jewelry that may come in contact with the Patch.
