Chapter 5: ECG Monitoring
Warning
Unplug the ECG cable from the socket, the error message "ECG NO CABLE" should be
displayed on screen.
Warning
Before monitoring, check ECG cable safety and replace cables that are damaged,
scratched, torn, or their distorted lead-wires.
Warning
Pay attention that ECG cable is not subjected to tension during connection.
Warning
ECG cable may be damaged if they are connected to a patient during defibrillation. Cables
that have been connected to a patient during defibrillation should be checked for
functionality before being used again.
Warning
To ensure patient safety, all leads must be attached to the patient. Make sure that there is
no contact between the conductive parts of electrodes, including the neutral electrode and
any other conductive parts including earth.
Warning
Use only one type of electrode on the same patient to avoid variations in electrical
resistance. For ECG monitoring, it is recommended to use silver/silver chloride electrode.
When dissimilar metals are used for different electrodes, the electrodes may cause large
offset potentials due to polarization, which may be severe enough to prevent obtaining an
ECG trace. Using dissimilar metals may also increase recovery time after defibrillation.
Warning
Verify lead fault detections prior to the start of monitoring phase.
Warning
Check once a day whether there is any skin irritation resulted from the ECG electrodes. If
so, replace electrodes or change their sites.
