DO not contact any other conductive parts (including ground) with any conductive parts of
electrodes, lead wires, and cable.
This patient monitor can withstand the discharge of a defibrillator and the interference from
the electrosurgical unit. Readings may be inaccurate for a short time after or during using
a defibrillator or electro-surgical unit.
Transients caused by cable circuitry blocks while monitoring may cause an artifact on
ECG signals yielding wrong heart rate reading and even triggering a false alarm.
Accurately locate the electrodes and cable according to this manual's instructions for
using electrodes. Proper placement decreases the chance of these transients.
ECG cable and lead wires may be damaged while using a defibrillator. Perform a function
check on the cable and lead wires before reuse.
When the monitor is inoperable due to an overload of ECG signal or saturation of any part
of the amplifier, it prompts "Lead(s) off" to remind the operator.
The user should eliminate any potential predictable hazards caused by the summation of
leakage currents when several items are interconnected.
When plugging or unplugging the ECG cable, be sure to hold the head of the connector
and pull it out.
Checking for the shelf life of the electrodes, and do not use the expired electrodes.
7.3 Preparing to Monitor ECG
7.3.1 Preparing the Patient and Device
1. Skin preparation
Clean and scrap skin to ensure low sensor impedance if necessary. Mild soap and water are recommended
as a skin cleanser. Scraping the skin gently with a dry washcloth, gauze, for skin preparation is helpful to
remove the non-conductive skin layer.
Note
If alcohol is used as a cleanser, it is recommended to have a 30-second drying time for a
better connection.
2.
Connect the cable to the connector marked with the "ECG" icon on the signal input panel.
3.
Place the electrode to the patient according to Section 7.3.2 ECG Electrodes Placement.
4.
Attach the ECG lead wires to the electrode
5.
Make sure the monitor is turned on and is ready for monitoring.
6.
After starting the monitor, if the electrodes become loose or disconnected during monitoring, the
system displays "LEAD OFF" on the screen to alarm the operator.
It might not display ECG waveform when using ECG cable with 3 lead wires while the setting of
