Patient Return Electrodes

Function of the Patient Return Electrode

The function of the patient return electrode is to remove current from the patient safely. A return electrode burn occurs when the heat produced, over time, is not safely dissipated by the size or conductivity of the patient return electrode.

BURN = (Current x Time) / Area
