Connecting ECG leadwire sets to ECG trunk cables
•
For 3-lead ECG, use the Multi-Link 3-lead ECG cable with
integrated leadwires or connect a 3 leadwire set to the Multi-Link
3- or 5-lead ECG trunk cable.
•
For 5-lead ECG, connect a 5 leadwire set to the Multi-Link 5-lead
ECG cable.
Preparing the patient's electrodes sites
Excessive body hair or skin oil reduces electrode contact with the
skin and decreases the quality of electrode signal. When preparing
the electrode sites, avoid bones close to skin, obvious layers of fat
and major muscles.
1. Shave any hair from the electrode sites.
2. Gently rub the skin surface to increase capillary blood flow.
3. Clean the skin with alcohol or a mild soap and water solution to
remove dead skin cells and oil.
4. Dry the skin completely before applying the electrodes.
NOTE: Do not use the electrodes with dissimilar metals.
Applying the electrodes to the patient
1. Place the electrodes on the prepared sites.
2. Stabilize the electrode and leadwire with a leadwire stress loop
near the electrode.
3. Tape the stress loop to the patient (excluding neonates).
A secured stress loop prevents leadwire rotation on the electrode
snap, leadwire tugging at the electrode, and ECG artifact.
