Pulse rate: Description
Description
The PR (pulse rate) measurement displays heartbeats per minute (bpm), the
source of the heartbeat data, a blinking heart icon and upper and lower alarm
limits for the parameter. A beep provides an audible representation of the
heartbeat. Also, the heart icon and the beep follow suit with the actual rhythm of
the heart. The faster the heartbeat, the faster the icon blinks and the beep
sounds, and vice versa.

The PR parameter receives data and waveform either from the NIBP parameter
or the SpO
or the SpO
2
parameter (Masimo SET
®
, Nellcor or GE TruSignal). The SpO
2
parameter is always the primary data source for PR (displayed in yellow)
whereas NIBP is the secondary (the PR displayed in the same color as the NIBP).

If pulse rate data cannot be obtained from SpO

in the PR window. If there is a recent enough NIBP for PR, it is displayed. The data

When the NIBP measurement is complete, a value is displayed in the PR window.
The value is displayed as long as the results of that determination are displayed
or until SpO

NOTES
If Masimo rainbow SET
®
is the data source, the pulse rate values are filtered
by an averaging technique that determines how quickly the reported values
respond to changes in the patient’s saturation. Increased averaging time
affects time to alarm for SpO

When NIBP is in STAT mode and is the source of pulse rate, the pulse rate
value is not checked against its limits upon completion of the measurement.

Due to the algorithms the various sources use to measure the heartbeat,
values in the PR window may differ when the monitor changes from one
source to another.

A patient’s vital signs may vary dramatically during the use of
cardiovascular agents such as those that raise or lower blood pressure or
those that increase or decrease heart rate.

those that increase or decrease heart rate.
If an SpO
2
-derived pulse rate is erratic, the pulse oximeter parameter may
be unable to measure the pulse. If the pulse beep tone does not sound with
each pulse, the pulse beep volume is turned off, or the speaker is
malfunctioning.

Pulse rate alarm limits
Refer to
on page 3-14 to set up Upper and Lower alarm limits
for Pulse Rate. The range for all sources is the same: Upper is 35 to 235 bpm and
Lower is 30 to 230 bpm. The limits can be set in increments of 5 bpm.
Lower is 30 to 230 bpm. The limits can be set in increments of 5 bpm.
When NIBP is the source for STAT mode measurement, the pulse rate value is
