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.
9.6.2 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.
9.6.3 Smart Lead Off
When Electrode Type is 5 Electrodes, 6 Electrodes or 10 Electrodes and Smart LeadOff is set
to On, if the current selected calculation lead cannot detect ECG signal, the monitor
automatically switches the corresponding lead as calculation lead, and switches the waveform
display of calculation lead at the same time. When ECG electrode is re-connected, and the
original calculation lead recovers its signals, the monitor automatically switch to the original
calculation lead.
To change the smart lead off setting, select ECG Setup > Smart LeadOff, and select the desired
setting.
NOTE:
When Electrode Type is set to AUTO, the smart lead off function will be automatically
turned on and cannot be turned off.
9.6.4 ECG Screen Layout
It varies with Electrode Type. When Electrode Type is set to 3 Electrodes, Screen Layout can
be set to Normal, and it can display one ECG waveform on the main screen.
