Preparing the Patient
Preparing the Patient's Skin
Careful skin preparation is the key to an interference-free ECG. Signal quality is
indicated on the device via the Hookup Advisor indicator.
1. Select the electrode placement sites for ECG monitoring or diagnosis per the
protocol specified by the hospital or physician.
Refer to “Electrode Placement” on page 47 for diagrams and descriptions of
electrode placement for various protocols.
2. Ensure that each site is dry, clean, and free of excessive hair.
NOTE:
Do not use solvents to clean the skin; solvents trapped under electrodes
may lead to abnormal skin reactions.
3. To prepare for a stress test, do the following:
a. Mark each electrode site with a felt tip pen.
b. Degrease each site with a skin preparation cream.
c. Use a mild abrasion to remove the mark left by the felt tip pen.
4. Apply electrodes to the prepared sites.
Electrodes should be placed only by a physician or ECG technician.
WARNING:
SHOCK HAZARD — Touching the conductive elements cancels the protection
provided by the isolated signal input.
Ensure that conductive parts of the electrodes or lead wires do not come in
contact with other conductive parts.
5. Look at the lead-check screen for indication of lead problems.
NOTE:
Use only electrodes and contact agents recommended by GE Healthcare.
The signal quality on the lead-check screen is not indicated until the RA/R
electrode is applied. If RA/R becomes disconnected, the system will report
that all electrodes are off the patient.
