7.3 Preparation for Monitoring ECG
7.3.1 Preparing the Patient’s Skin
Proper skin preparation is essential in obtaining an accurate ECG reading. Electrode sites
should be clean and dry and should provide a smooth flat surface. Incidental electrical
activity and inaccurate readings may arise from incorrect skin preparation.
The following procedure is recommended for secure electrode application:
1. Shave the chest hair from the electrode sites in a circular area with a diameter of 2
to 4 inches.
2. Use a dry gauze pad to remove excess skin oils, skin cells and residue from the
electrode sites. Never rub the skin until it is raw or bleeding.
7.3.2 Positioning the Electrodes
NOTE
•
After defibrillation, the waveform recovers within 10 seconds applied in
accordance with the manufacturer’s instructions for use.
NOTE
•
Prepare the electrode site with alcohol only if the skin is extremely
greasy. If alcohol is used as a drying agent, always allow the skin to dry
before placing the electrode on the skin.
NOTE
•
Store electrodes at room temperature and open just prior to use.
•
Avoid more than one type of electrode on a patient because of varia-
tions in electrical resistance.
•
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 mus-
cle activity and could lead to false arrhythmia calls.
