10.3 Selecting the Active Alarm Source
In most cases the HR and pulse numerics are identical. In order to avoid simultaneous alarms
on HR and Pulse, the monitor uses either HR or Pulse as its active alarm source. To change
the alarm source, select [ Alm Source ] in the [ ECG Setup ] or [ SpO
2
Setup ] menu and then
select either:
„
[ HR ]: The monitor will use the HR as the alarm source for HR/pulse.
„
[
PR
]: The monitor will use the PR as the alarm source for HR/pulse.
„
[ Auto ]: If the [ Alm 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 a valid heart rate is available. If the heart rate becomes unavailable, for example if
leads becomes disconnected, and a pulse source is switch on and available, the monitor
will automatically switch to Pulse as the alarm source. When the Leads Off condition is
corrected, the monitor will automatically switch back to the heart rate as the alarm
source.
10.4 QRS Tone
When PR is used as the alarm source, the PR source will be used as a source for the QRS
tone. You can change the QRS volume by adjusting [ Beat Vol ] in the [ SpO
2
Setup ] menu.
When a valid SpO
2
value exists, the system will adjust the pitch tone of QRS volume
according to the SpO
2
value.
