Patient Monitor User Manual Monitoring ECG
- 60 -
NOTE:
1
If an ECG waveform is not accurate, while the electrodes are tightly attached, try to
change the lead.
2
Interference from a non-grounded instrument near the patient and ESU interference
can cause inaccuracy of the waveform.
8.9 ECG Menu Setup
8.9.1 Setting Alarm Source
To change the alarm source, please select ECG Setup > Alarm Source, then a pop-up box is
displayed:
HR: the monitor considers the HR as HR/PR alarm source;
PR: the monitor considers the PR as HR/PR alarm source;
AUTO: If the Alarm Source is set to Auto, the monitor will use the heart rate from the ECG
measurement as the alarm source whenever the ECG measurement is switched on and at least one
ECG lead can be measured without a technical condition.The monitor will automatically switch
to Pulse as the alarm source if:
–a valid ECG lead can no longer be measured and
–a pulse source is switched on and available.
The monitor then uses the pulse rate from the measurement currently active as system pulse.
While Pulse is the alarm source, all arrhythmia and ECG HR alarms are switched off. If an ECG
lead becomes available again, the monitor automatically uses HR as alarm source.
8.9.2 Smart Lead Off
In 5 LEADS, 12 LEADS mode, if CH1 and CH2 can not be measured because of the lead off or
other reasons, it can shift to other modes to collect an ECG waveform.
To change smart lead off setting, please select ECG Setup > Smart Leadoff, then a pop-up
menu is displayed.
8.9.3 Setting Beat Volume
Beat volume is from HR or PR, depending on your HR alarm setting. Five selections are
available: 0, 1, 2, 3, 4, 5. 5 indicates the maximum volume. 0 indicates the minimum volum.
To change the beat volume, first select ECG Setup > Beat Volume, then select an approiate
volume from the pop-up list.
8.9.4 ECG Display
It varies with Lead Type. When Lead Type is set to 3 Leads, Display can be set to Normal, and
it can display one ECG waveform on the main screen.
When Lead Type is set to 5 Leads, Display can be set to Normal, Full-Scr and Half-Scr. Select
Normal to display two ECG waveforms on the main screen; select Full-Scr to display seven
ECG waveforms which occupy the area of seven waveforms on the main screen; Select Half-Scr
