Chapter 12 Monitoring PR
12.1 Overview
The pulse numeric counts the arterial pulsations that result from the mechanical activity of the
heart in beats per minute (bpm). You can obtain a pulse from any measured SpO
2
signal or any
arterial pressure.
12.2 Setting PR Source
The monitor provides PR source options. You can select SpO
2
or arterial pressure labels as the
PR source in the PR Source list on the PR Setup menu.
NOTE:
In the
PR Source
list, an arterial pressure label accompanied with a label with brackets
indicates this label is in conflict. Do not select a conflicting label as the PR source.
12.3 Setting PR Volume
Select PR Setup > PR Volume , then select the appropriate setting for the PR volume: five bars
represent the maximum volume and one bar represents the minimum volume. If none of bars are
selected, the PR volume will be off. Beat frequency of pulse has positive correlation with
measurement value.
12.4 Selecting the Active Alarm Source
In most cases, the HR and PR numerics are identical. In order to avoid simultaneous alarms on
HR and PR, the monitor uses either HR or PR as its active alarm source. To change the alarm
source, select either
ECG Setup > Alarm Source or PR Setup > Alarm Source , then select:
HR : if you want HR to be the active alarm source.
PR
: if you select PR as the active alarm source, the monitor will prompt you to confirm your
choice. Be aware that if you select PR as the alarm source, ECG HR alarms are switched off.
AUTO : If the alarm 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 at least
one ECG lead can be measured without a technical alarm condition. The monitor will
automatically switch to PR for the alarm source if:
•
a valid ECG lead can no longer be measured and
•
a PR source is switched on and available.
The monitor uses the pulse rate from the currently active measurement as system pulse. While PR
is the alarm source, all arrhythmia and ECG HR alarms are switched off. If an ECG lead becomes
available again, the monitor automatically uses HR as alarm source.
NOTE:
Pulse alarms are only generated when the active alarm source is set to
PR
, a pulse
source is set as system pulse and pulse alarms are switched on.
