Patient Monitor User Manual Monitoring ECG

to PR as the alarm source if:
–a valid ECG lead can no longer be measured and
–a PR source is switched on and available.
The monitor then uses the pulse rate from the measurement currently active as system pulse.
While PR 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.
8.6.2 Setting Beat Source
To change the beat source, select either ECG Setup > Beat Source or PR Setup > Beat Source.
Select from the following options:
HR: HR is HR/PR beat source;
PR: PR is HR/PR beat source;
AUTO: If the Beat Source is set to AUTO, the monitor will use HR as the beat source whenever
the ECG measurement is switched on, and at least one ECG lead can be measured. The monitor
will automatically switch to PR as the beat source if:
• a valid ECG lead can no longer be measured and
• a PR source is switched on and available.
If an ECG lead becomes available again, the monitor automatically uses HR as beat source and
the monitor gives a "Di" tone with a blinking heart displaying in the HR parameter box
when one heartbeat is detected. While a pulse is detected, the monitor gives a "Da" tone.
8.6.3 Smart Lead Off
When Lead Type is 5 Leads or 12 Leads and Smart LeadOff is set to On, if the selected ECG
waveform cannot be measured because of lead-off or other reasons, it will automatically switch
to another available lead channel via which a waveform can be measured. And the lead name
above the display ECG waveform also automatically turns into the current one.
To change the smart lead off setting, select ECG Setup > Smart LeadOff, and select the desired
setting.
8.6.4 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
to display seven ECG waveforms on the screen, occupying the area of four waveforms.
When Lead Type is set to 12 Leads, Display can be set to Normal and 12 Leads. Select
Normal to display two ECG waveforms on the main screen; select 12 Leads to display 13 ECG
waveforms.
