If using pre-gelled electrodes, verify that there is enough gel in the gel-filled area.
Preparing the Patient’s Skin
The quality of ECG monitoring depends largely on the strength and quality of the
signals received by the electrodes. Careful skin preparation and application techniques
assure strong signals with minimal artifact and interference.
Select flat, non-muscular sites to position the electrodes and follow the clinical
techniques of your hospital. We suggest the following standard technique:
1. Prepare the skin by clipping or shaving excess hair.
2. Remove any skin residue or oils with an alcohol pad.
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.
NOTE: Never use disposable electrodes after their expiration dates or when gel has
dried out.
