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 the 
IBP section). The displayed pulse numeric is color-coded to match its source.   
 
 
(1) PR Source  
(2)  PR: detected beats per minute. 
 
 
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 central monitoring system, if available.   
 
To set which pulse rate as PR source:   
1. Enter the [SpO
2
 Setup] menu. 
2. Select [PR Source] and then select a label or [Auto] from the popup menu. 
The popup 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 popup 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 popup menu.
