7.3.2 Positioning the Electrodes
NOTE
•
Store electrodes at room temperature and open just prior to use.
•
Avoid more than one type of electrode on a patient because of variations in
electrical resistance.
•
Give special attention to the type of electrode used. Because some electrodes
may generate greater electric offset due to polarization.
•
Do not use electrodes of different metallic materials.
•
Avoid placing electrodes directly over bone prominences or over any high
activity movement areas such as shoulders or arms because muscle motion
produces electrical activity. If an electrode is placed over a large muscle such as
the pectorals, the device may detect this additional muscle activity and could
lead to false arrhythmia calls.
•
Using a Transcutaneous Electrical Nerve Stimulator (TENS): since A tens UNIT
transmits electrical impulses, avoid placing ECG electrode near the TENS
electrodes. ECG electrodes may need to be repositioned and the ECG lead
viewed may need to be adjusted until the optimum ECG tracing is obtained.
To position the electrodes, follow this procedure:
1. Peel the backing off of the electrode. Visually inspect the contact gel medium for
moistness. If the gel medium is not moist, do not use the electrode patch. Dry elec-
trode patches are not conductive.
NOTE
•
To prevent evaporation of the contact gel medium, peel the backing off of the
electrode patch only when it is ready for use.
•
If using the snap type lead wires, attach the electrode to the lead wire before
placing the electrode on the patient.
2. Attach the electrode patch to the skin at the prepared site. Smooth the electrode
patch down in a circular motion to ensure proper skin contact. If using soft gel elec-
trodes, never push down directly over the contact gel medium as this may displace
the gel and cause monitoring artifact. If using hard gel electrodes, it is recommended
that during application, the center of the electrode should be slightly pressed onto
the skin to ensure direct contact. Consult the electrode manufacturer’s instructions
for specific use. Ensure all the electrodes are applied to the patient properly.
3. Secure the lead wires to the patient according to hospital practice.
