Select the ECG parameter area or wave ECG area or select the
[Settings] smart hotkey and “Parameter Setup >>
”
and “ECG
Setup >>
”
to pop up the “ECG Setup” menu, which is as shown below. You can set the ECG through the “ECG Setup” menu.

“
ECG Setup” menu
Select “HR Source”, and set the heart rate source.
“Auto”: Automatically select HR source.
“ECG”: Select ECG monitoring as the HR source.
“SpO2”: Select SpO2 monitoring as the HR source.
Select “Calculated Channel” and select heart rate calculated channel.
“Auto”: Automatically select Heart Rate calculated Channel.
“I”: Select the first ECG waveform as the Heart Rate calculated Channel.
“II”: Select the second ECG waveform as the Heart Rate calculated Channel.
“V”: Select the third ECG waveform as the Heart Rate calculated Channel.
Select “ECG1” / “ECG2” to set the display wave channel. Select “ECG1”/ “ECG2”, and set the names of upper ECG wave and
lower ECG wave on the screen.
ECG1/ECG2 should not be the source of the same wave, source waveform can be set I/II/III/AVR/AVL/AVF/V.
Select “Wave Gain”, and set the ECG wave gain. When the wave is shorter, increase the wave gain factor appropriately; when
the wave is high or the peak cannot be displayed, reduce the wave gain appropriately, gain can be set Auto/×0.25/×0.5/×1/×2.
When Big ECG interface is selected, gain can be set Auto/×0.25/×0.5/×1/×2/×4.
Select “Wave Speed”, and set the wave speed. The wave speed is “12.5mm/s”/“25mm/s”/“50mm/s”. The default is 25mm/s.
Select “Filter”, and set the filter mode:
“Diagnostic”: Diagnostic mode
“Monitor”: Monitor mode
“Surgery”: Surgery mode
Select “Arrhythmia Analysis>>”, and set the alarm switch, alarm level, alarm record.
Select “ST Analysis>>”, and set the ST analysis, ST Channel, ST Alarm Setup.
“ST analysis”: You can set “Off” or “On”.
“ST Channel”: You can set “1”, “2”, “3”.
“ST Alarm Setup”: and set the alarm switch, alarm level, alarm record.
Select “Other Setup>>”, and set the QRS Volume, Lead Type , Notch Filter, Pace Maker.
7.6 Alarm setup
Select “Alarm Setup >>

“Alarm Setup” interface to set ECG related alarms; see 6.5 Alarm Setup for the setting method.
8 RESP
8.1 Overview
Thoracic electrical bio impedance is a method used for measuring the respiration. When the patient is breathing, the thoracic
impedance between two ECG electrodes changes due to thoracic activity. The monitor generates a respiratory wave on the screen
by measuring the changing impedance value. The monitor calculates the respiration rate (RR) according to the wave cycle.
8.2 Safety information`
NOTE
Respiration monitoring does not apply to patient with large range of activities, as this may lead to false alarm.
WARNING
Do not use anti-electric knife ECG cable for respiration monitoring.
Respiration measurement cannot identify the apnea because it will alarm if the next respiration is not detected
in the predetermined period after last respiration, and therefore it cannot be used for diagnostic purpose.
