If the SpO
2
value is effective, the monitor also adjusts the QRS tone (pitch tone) according to the SpO
2
value. For
information, see
13.6.8 Setting the SpO2 Tone Mode.
13.7.3 Setting the PR Source
Current pulse source is displayed in the PR numeric area. The PR from current pulse source has the following
characteristics:
■ PR is monitored as system pulse and generates alarms when you select PR as the active alarm source.
■ PR is stored in the monitor’s database and reviewed in the graphic/tabular trends; in trend graphs, as the PR
curve is in the same color with that of the PR source , it is unlikely to distinguish the PR source ;
■ PR is sent via the network to the CMS, if available.
To set which pulse rate as PR source, follow this procedure:
1. Select the SpO
2
numeric area or waveform area to enter the SpO2 menu.
2. Select the
PR Setup tab.
3. Set
PR Source.
The
PR Source menu displays the currently available PR sources from top to bottom by priority. When you select
Auto, the system will automatically select the first option as the PR source. If the current PR source is unavailable,
the system will automatically switch
PR Source to Auto. When you select IBP, the system will automatically
select the first pressure label as the PR source.
