7.3 Monitoring steps
7.3.1 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.

Place the electrode on the patient.
 Connect the ECG cable and ECG interface.
WARNING

Check if the lead is adequately attached and do not have any damage before monitoring. When the ECG cable is
unplugged, the screen will display
“
ECG Lead Off” prompt, and trigger an audible and visual alarm.
7.3.2 Selecting lead
 Select the ECG parameter area or wave area
→
“ECG Setup” menu.

Select “Other Setup >>
”→
“ECG Other Setup” menu.
 Select “Lead Type”, and select the ECG lead as needed.

“3-Lead”: 3-lead; ECG wave options: I, II, III.
