neutral electrodes, are attached to the patient and prevent them from contact
with the conductive parts or ground.
Periodically check the skin that the electrode is placed at; if there is any sign of
allergy, replace the electrode or change the placement position.
Electrosurgery (ESU) device interference, defibrillator discharge:
When the patient needs defibrillation, do not use non-defibrillator type ECG
cables.
During defibrillation, the operating personnel shall not touch the patient,
tables and instrument.
During defibrillation, the ECG cable connected with the patient’s body may
be damaged. Check if the function is normal again before using these cables.
Recover within 10 seconds after defibrillation and will not lose any stored
data. During electrosurgery (ESU) or defibrillation, the measurement
accuracy may be temporarily reduced. This does not affect the safety of the
patient or the instrument.
Do not expose this equipment to X-ray or strong magnetic fields (MRI).

Monitoring Steps
12.3.1
Preparation
Before placing the electrode, prepare the patient's skin in the following steps:
Skin preparation: Since the skin is a poor conductor, it is very important to treat the
patient's skin for electrode placement appropriately to make good contact between the
electrode and the skin. Select the flat position with less muscles for the electrode
placement, and refer to the method below for treatment of the skin:
Remove the body hair at the position for electrode placement.
Gently rub the skin at the position for electrode placement to remove dead skin
cells.
Wash the skin thoroughly with soap and water (do not use ether and pure alcohol,
as this will increase the skin's impedance).
Dry the skin completely before placing the electrode.
Install the spring clip or stud prior to the placement of the electrodes.
