ECG Monitoring
Patient Preparation
Proper patient preparation and placement of the electrodes is the
single most important factor in obtaining a good ECG signal.
1. Have a thorough understanding of the patient’s history. This may
assist in determining where electrodes are placed.
2. Prepare the patient by ensuring that hair is removed from the
locations where you intend to place the electrodes. Use
Nu-Prep gel with cotton gauze or a washcloth. A small amount
of Nu-Prep gel should be applied to the cotton gauze or wash
cloth. The area where the electrode is to be placed should then
be thoroughly cleaned by rubbing it in a circular motion.
3. ConMed Invisitrace electrodes are recommended for use with
the Veris monitor. They should be placed on the prepared
locations ensuring that they securely adhere to the skin surface.
NOTES:
Do not use alcohol. Alcohol removes electrolytes from the skin
and decreases the quality of the electrical contact.
Medrad recommends the use of ConMed Invisitrace electrodes.
These electrodes are MRI compatible. See “Accessories” in
Appendix D for a complete list of recommended electrodes and
accessories.
Use three (or five) new, MR-compatable electrodes.
• Connect only MEDRAD approved 3-lead or 5-lead ECG cables
from the patient to the ECG module. Do not connect any other
signal source to the ECG module.
• When positioning the patient in the MR scanner, locate the
electrodes less than four inches from each other and do not loop
the leadset. Insulate the leadset from the patient. It is not
dangerous for loops to form in the fiber optic cable.
• Use only accessories designated for use with this monitor. Use
of accessories not designated for use with the Veris monitor can
cause inaccurate measurements and/or a safety hazard for the
patient.
• Do not allow the conductive parts of the patient electrodes to
contact other conductive parts, including ground (earth).
