User Manual for Vital Signs Monitor

Do not use the device to monitor the patient if there are indications of damage or reminders of
error. Please contact the local dealer or our company.
It’s recommended to delay 1 minute to start it again.
3.3 Sensor Placement and Connection
3.3.1 ECG Cable 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.
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.
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:
Figure 3.3 Electrode Location
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 wave with 3 leads. The 5 leads should be used to have ECG
wave.
