2. Select electrodes to be used. Use only one type of electrode on the same patient to avoid variations in electrical
resistance. For ECG monitoring, it is strongly recommended to use silver/silver chloride electrodes. When
dissimilar metals are used for different electrodes, the electrodes may be subject to large offset potentials due to
polarization. Using dissimilar metals may also increase recovery time after defibrillation.
3. Prepare the electrode sites according to the electrode manufacturer's instructions.
4. Skin clean
Ø Clean and dry-abrade skin to ensure low sensor impedance. Mild soap and Water is recommended as a skin
cleanser.
Note: Alcohol is not recommended as a skin cleanser; it leaves a film layer that may cause high sensor
impedance. If alcohol is used, ensure 30-second dry time.
Ø Dry-abrading the skin gently with a dry wash cloth, gauze, or skin preparation product is helpful to remove
the non-conductive skin layer.
The symbol indicates that the cable accessories are designed to have special protection against electric
shocks, and is defibrillator proof.
The locations of the electrode are in the following Figure:
Note: If skin rash or other unusual symptoms develop, remove electrodes from patient.
5. After starting the monitor, if the electrodes become loose or disconnected during monitoring, the system will
display "LEAD OFF" on the screen to alarm the operator.
% It might not display ECG waveform when using 3 lead wires but with the setting of 5 lead
wires. The 5 lead wires should be used to get full ECG waveform simultaneously.
6 The ECG leads and their corresponding locations are as follows:
