10 Monitoring PR
10.1 Introduction
The pulse numeric counts the arterial pulsations that result from the mechanical activity of the heart. You can display a
pulse from any measured SpO
2
or any arterial pressure (see chapter 14 Monitoring IBP). The displayed pulse numeric is
color-coded to match its source.
1. PR: detected beats per minute.
2. PR Source
NOTE
A functional tester or SpO
2
simulator can be used to determine pulse rate accuracy.
10.2 Setting the PR Source
The current pulse source is displayed in the PR parameter area. The pulse rate chosen as pulse source:
is monitored as system pulse and generates alarms when you select PR as the active alarm source;
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 the PR source , it is unlikely to distinguish the PR source;
is sent via the network to the CMS, if available.
To set which pulse rate as PR source:
1. Enter the [SpO2 Setup] menu.
2. Select [PR Source] and then select a label or [Auto] from the pop-up menu.
The pop-up 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 from the pop-up menu. When 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 from the pop-up menu.
