Attaching the ECG electrodes
Warning
Check the electrode attaching condition in a certain time interval.
If skin integrity changes, move the sensor to another site.
Caution
•
Before attaching the electrodes, use alcohol to clean the body sites where the
electrodes are to be attached. Oil or perspiration on the site increases the contact
resistance and causes poor contact between electrode and patient.
•
Wipe the body sites that are wet with the alcohol, using a clean, dry cotton.
•
Do not use the disposable electrode when the paste is dry.
For ECG monitoring, the chest lead configuration as shown below is recommended. It provides the
waveform that is similar to that obtained using the standard bipolar limb lead.

Note
•
To ensure stable monitoring, connect cables firmly and attach the electrodes securely so that they are
in good contact throughout monitoring
•
Some patients have a weak R-wave pulse. In that case, change the induction method.
