Notes

Attaching the ECG Lead Cable

WARNINGS
Given in relation to the patient's limbs, designators and colors of the ECG lead cable clips 
reference connection locations on the Quadtrode electrode. Also, note that depending upon the 
lead cable version, AAMI (Association for the Advancement of Medical Instrumentation) or IEC 
(International Electrotechnical Commission), different designators and colors are used for these 
references. The diagrams below illustrate the lead cable attachment locations to the Quadtrode, 
according to the ECG lead cable version and limb.
5‐12  Monitoring ECG                                                                                                                                     Expression MR400 Instructions for Use
Step
Action
3
If necessary, shave the application area to remove hair from the 
selected Quadtrode electrode site(s).
4
Apply ECG Skin Prep Gel (REF 989803152291) to a gauze pad.
5
Briskly rub the selected site(s) with the gauze pad (the skin may 
turn pink). 
6
Remove any excess gel with a clean gauze pad.
7
Place the Quadtrode electrode at the prepared site(s) on the 
patient. 
The ECG Skin Prep gel contains light abrasive pumice and saline that clean and enhance
the conductive properties of the skin, thus enhancing ECG performance. This practice also
helps remove ambient artifacts.
Isopropyl/rubbing alcohol must not be used to prep the site as it breaks down the conductive
properties of the skin, thus degrading ECG performance.
Never use any ECG lead cables other than the specified ECG lead cables.
High levels of RF energy may cause patient heating or burns.
An ECG lead cable that becomes inadvertently looped during an MRI examination
may act as conductive lines for RF induced currents, resulting in excessive heating and
possible burns. When lead cables or other cables form a conductive loop in contact
with the patient's tissue, minor to severe burning can result. Please refer to the
additional information in Appendix E to prevent excessive heating associated with
MRI procedures. Follow steps to minimize the risks of MRI-related heating on page 5-
20.
