• Using a 5-lead set, the ECG can derive up to two waveforms from two different leads. For requested lead,
you may choose from the left side of ECG waveform.
• The monitor displays the Heart Rate (HR), ST segment and Arrhythmia analysis.
• All of the parameters above can be set as alarm parameters.
Note
• In the default settings of the monitor, the ECG waveforms are the first two waveforms from top in the
Waveform Area.
11.2 Precautions during eCG Monitoring
Warning
• Do not touch the patient, table nearby, or the equipment during defibrillation.
• Please use anti-defibrillation ECG cable during defibrillation.
• Use only the original ECG cable for monitoring.
• When connecting the cables and electrodes, make sure no conductive part is in contact with the ground.
Verify that all ECG electrodes, including neutral electrodes, are securely attached to the patient.
Note
Interference from a non-grounded instrument near the patient and ESU interference can cause inaccuracy of
the waveform.
11.3 Monitoring Procedure
11.3.1 Preparation
1. Prepare the patient's skin prior to placing the electrodes.
• The skin is a poor conductor of electricity, therefore preparation of the patient's skin is important
to facilitate good electrode contact to skin.
• Shave hair from sites, if necessary.
• Wash sites thoroughly with soap and water. (Never use ether or pure alcohol, because this increases
skin impedance).
• Rub the skin briskly to increase capillary blood flow in the tissues and remove skin scurf and grease.
2. Attach clip or snap to electrodes prior to placement.
3. Put the electrodes on the patient. Before attaching, apply some conductive jelly on the electrodes if the
electrodes are not electrolyte self-supplied.
4. Connect the electrode lead to the patient's cable.
5. Make sure the monitor is ready with power supply.
Note
For protecting environment, the electrodes must be recycled or disposed of properly.
Warning
• Check everyday whether there is skin irritation resulted from the ECG electrodes. If so, replace electrodes
every 24 hours or change their sites.
• Verify lead fault detection prior to the start of monitoring phase. Unplug the ECG cable from the socket,
the screen will display the error message "ECG LEAD OFF" and the audible alarm is activated.
11.3.2 Installing eCG lead
Placing the Electrodes for ECG Monitoring
Electrode placement for 5-lead set (Figure11-1)
• Red (R) electrode - Be placed near the right shoulder, directly below the clavicle.
• Yellow (L) electrode - Be placed near the left shoulder, directly below the clavicle.
• Black (N) electrode - Be placed on the right hypogastrium.
• Green (F) electrode - Be placed on the left hypogastrium.
• White (C) electrode - Be placed on the chest as illustrated in the F Figure 11-2.
Note
The following table gives the corresponding Electrode names used in Europe and America respectively.
(Electrode names are represented by R, L, N, F and C respectively in Europe, whose corresponding Electro-
de names in America are RA, LA, RL, LL and V.)
