3. Remove the outer epidermal layer as required to reduce skin
impedance. Mildly abrade only the electrode contact site with
ultrafine sandpaper (220-400 grit). Apply the electrodes one
at a time and make sure the electrode gel is in contact with
the abraded skin area.
4. For severely diaphoretic patients, use a benzoin prep for
tighter adherence of the electrodes.
5. Inspect the electrode gel to make sure it is moist. Apply the
pad with a circular motion on the adhesive area first, then
press gently on the gel area to prevent the gel from being
squeezed out.
6. Change electrodes every 24-48 hours to ensure a good quality
signal. However, if the electrocardiographic pattern becomes
less distinct, if the patient is diaphoretic, or if skin irritation
develops, the electrodes must be changed and reapplied
sooner.
