3.3 Connection
3.3.1 ECG Connection
ECG measurement is to collect the ECG signal via the ECG electrodes. Electrode connects the patient and the
lead. The lead connects the monitor. The locations of the electrodes are very important for obtaining accurate
ECG signals.
1. Connect the cable to the right-panel connector marked with the ECG icon.
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
➢Clean and dry-abrade skin to ensure low sensor impedance. Mild soap and Water is recommended as
a skin cleanser.
➢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 and accessories are designed to have special protection against
electric shocks, and is defibrillator proof.
The locations of the electrode are in the following Figure:
Figure 3.5 Electrode Location
Note: If skin rash or other unusual symptoms develop, remove electrodes from patient.
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.
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.

It might not display ECG wave with 3 leads. The 5 leads should be used to have ECG wave.
5. The ECG leads and their corresponding locations are as follows:
Safety Instructions for ECG Monitoring
This Patient Monitor can only be equipped with ECG leads provided by our company; using ECG leads
supplied by other companies may cause improper performance or poor protection while using
defibrillator.
Electric parts of electrodes, leads and cable are forbidden to contact any other conductive parts
(including ground).
This Patient Monitor can resist against defibrillator and electrosurgical unit. Readings may be
inaccurate for a short time after or during using defibrillator or electrosurgical unit.
Transient caused by cable circuitry blocks while monitoring may be similar to the near real-time
heartbeat waveform, as a result resistance heart rate alarm rings. If you put the electrodes and cable in
proper places according to this manual’s instructions and the instructions for using electrode, the
chance of this transient occurring will be decreased.
To the patient with pacemaker, due to that this device has been designed to provide resistance to
pacemaker signal interference, generally the pacemaker pulse is not counted in heart rate
measurement and calculation, but when the cycle time of pacemaker pulse is over 2ms, it may be
counted. In order to reduce this possibility, observe the ECG waveforms on the screen carefully and do
NOT rely entirely on the heart rate display and alarm system of this monitor when monitoring this kind
of patients. Keep pacemaker patient under close surveillance.
Besides the improper connection with electrosurgical unit may cause burns, the monitor may be
damaged or arouse deviations of measurement. You can take some steps to avoid this situation, do
NOT use small ECG electrodes, choosing the position which is far away from the estimated Hertzian
waves route, using larger electrosurgical return electrodes and connecting with the patient properly.
No predictable hazard will be caused by the summation of leakage currents when several item of
monitor are interconnected.
ECG leads may be damaged while using defibrillator. If the leads are used again, please do the
functional check first.
When the monitor is inoperable due to an overload or saturation of any part of the amplifier, it will
prompt “Lead off” to remind operator.
