Monitoring PR
8.1 Overview
The pulse numeric counts the arterial pulsations that result from the mechanical activity
of the heart. The pulse value can be from SpO
2
or NIBP. The PR parameter area displays its
source.
(1) PR high limit
(2) PR low limit
(3) Pulse rate (PR): detected pulsations per minute.
(4) PR Source
NOTE

A function tester or SpO
2
simulator can be used to determine the pulse rate
accuracy.
8.2 PR Source
The current pulse source is displayed in the PR parameter area. The pulse rate is:

stored in the monitor’s database and reviewed in the graphic/tabular trends.

sent via the network to the central monitoring system, if available.
8.3 Pulse Tone
You can change the pulse tone volume by adjusting [ Beat Volume ] in the [ SpO
2
Setup ]
menu. When a valid SpO
2
value exists, the system will adjust the pitch tone of pulse
according to the SpO
2
value.
