6.7 Manual event
In the patient monitoring process, some events may have an impact on the patient, resulting in changes of some monitoring waves
or parameters. In order to assist in the analysis of these effects, you can manually record these events through the
[Event]
smart hotkey, and then view it in the event review, refer to15.4 Event Review for detailed operation.
6.8 Alarm record
When the monitor’s machine alarm system is powered down, all alarm records are not saved.
Physiological alarm can store 200 alarm records, if full of 200, the latest alarm records will replace the beginning of the record;
Technical alarm can store 100 alarm records, if full of 100, the latest alarm records will replace the beginning of the record.
7 ECG
7.1 Overview
Electrocardiogram (ECG) is produced by the continuous electrical activity of the patient's heart, and displayed with wave and
numeric on the monitor in order to accurately assess the physiological state of the patient at the time. The ECG cable should be
connected properly, so as to obtain a correct measurement value and normal display. This monitor can simultaneously display 7
ECG waves.
Patient cable consists of two parts.

Wires connected to the monitor
 ECG electrodes connected to the patient
Connect to the monitor with five lead ECG cable, and ECG can display two different waves by adjusting the two leads. You can use
the control knob to change the lead name on the left of the ECG wave on the screen and select the lead to be monitored.
The parameters displayed in the parameter area of the monitor include heart rate (HR), ST segment measurements and arrhythmia
counts per minute. All these parameters can be used as alarm parameters.
The monitor is designed for defibrillation proof, so the monitor operates normally after defibrillation.
NOTE

In the factory setup, ECG wave display in the first two waves from top in the wave area in the normal display
format.
7.2 Safety information
WARNING

To monitor ECG signal, ECG cable and ECG electrodes specified in this manual must be used.

When connecting the electrodes or patient cable, make sure that the patient is absolutely not connected with
any other conductive parts or in contact with the ground. In particular, make sure that all the ECG electrodes,
including the neutral electrodes, are attached to the patient and prevent them from contact with the conductive
parts or ground.

When using electrosurgical (ES) equipment, users should put ECG electrodes at middle of the ES earthing plate
and ES knives to prevent from burns. Cables of ES equipment cannot be wrapped with ECG cables together.

During use of ES equipment, don’t put electrodes near the earthing plate of such equipment, otherwise ECG
signals will be much disturbed.

For patients who wear a pace maker, pacing pulse analysis must be turned on. Otherwise, the pacing pulse may
be counted as a normal QRS wave, make the ECG signal too weak to detect the alarm.

Periodically check the skin that the electrode is placed at. If there is any sign of allergy or irritation, replace the
electrode or change the placement position.

Electrosurgical (ESU) device interference, defibrillator discharge

When the patient needs defibrillation, do not use non-defibrillator type ECG cables. For defibrillation
protection, please use the accessories specified by manufacturer. (Refer to Chapter 17. Accessories)

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.

The monitor will recover within10 seconds after defibrillation and will not lose any stored data. During
electrosurgery or defibrillation, the measurement accuracy may be temporarily reduced. This does not
affect the safety of the patient or the instrument.

Do not expose the monitor to X-ray or strong magnetic fields (e.g. MRI).
