Notes for Customers Using Reusable Electrodes
Each electrode must be attached securely. Straps must neither slide nor be so
tight as to cause discomfort.
The electrode paste, gel, or creme must cover an area the size of the electrode,
but must not extend beyond it, especially on the chest.
Notes for Customer Using Disposable Tab Electrodes
Disposable electrodes have conductive material on the adhesive side only.
The electrode tab must be placed between the jaws of the electrode adapter
clip, and remain flat. Do not attempt to place the jaws of the electrode adapter
so close to the circular part of the electrode that the tab of the electrode is
bent, or contact is made with the conductive gel. Gently tug on the electrode
adapter to ensure that the electrode adapter is properly placed on the
electrode.
Good and accurate placement on the first attempt should be your goal for each
electrode. Each time an electrode is lifted off the skin and attached again, the
adhesive gel becomes weaker and less effective.
NOTE Never mix reusable and disposable electrodes on the same patient.
