3.8.1 Preparation of Skin and Placement of Electrodes
Figure 3-2. Site for placement of electrodes (1) The following sites will be used for electrode placement. See Figure 3-2.- RA: below the distal end of the right clavicle, on the superior aspect of the
pectoralis major. - LA: below the distal end of the left clavicle, on the superior aspect of the
pectoralis major. - RL: right anterolateral surface of the abdomen at the level of the umbilicus.
- LL: left anterolateral surface of the abdomen at the level of the umbilicus.
- If the individual has a large amount of body hair, the electrodes can be moved
slightly to give better contact with the skin. To avoid unintended injury or
discomfort to the SP, this site will not be shaved. Move the electrodes
approximately 2 inches laterally. See the outer limit circles on RA and LA in
Figure 3-2.
Preparation of the sites for attachment of electrodes:- Briskly wipe the skin at placement site of electrode with a skin preparation
swab to remove any oils or lotions on the skin. - Lightly abrade the skin (no more than 6-8 swipes) with a fine abrasive strip
covering an area the size of the electrode.
