B40/B20 Patient Monitor

Preparing the patient and placing the electrodes
Preparing the patient
•
Prepare the skin properly to ensure optimal signal quality.
•
Shave any hair from the electrode site. Gently rub the skin surface to increase capillary
blood flow and remove dead skin cells and oil.
•
Clean the skin using a mild soap and water solution.
•
Dry the skin completely before applying the electrodes.
•
Pre-gelled electrodes are recommended. Check that the electrodes are moist and have
not dried out during storage.
Placing the electrodes
NOTES:
•
Pre-gelled ECG electrodes are recommended. Check the expiration date.
•
Make sure the electrode gel is moist.
•
Make sure the electrodes have good skin contact.
•
Replace all electrodes at least every 24 to 48 hours.
•
Use the Multi-Link electrosurgical unit (ESU) ECG patient cable when using the monitor in
the presence of an electrosurgical unit. This cable, with a built-in ESU filter, helps reduce
electrosurgical noise detected on the ECG signal.
•
Whenever a cable, electrode or V-lead is changed, the monitor automatically relearns.
When placing the electrodes, avoid bones close to the skin, obvious layers of fat and major
muscles.
Patient connection
NOTE: Keep the ECG cable, lead set and connectors dry. Avoid excessive use of liquids
when cleaning the cables and connectors.
