Pulse Rate: Description
Description
The Pulse Rate parameter is included in all Models. Pulse rate values can be
derived from one of two sources. In descending order of priority, they are pulse
oximetry (SpO
2
) and noninvasive blood pressure (NIBP). The derived values for
pulse rate appear in the Pulse Rate window.
While SpO
2
is in operate mode, SpO
2
is the primary source of the pulse rate. At
any time while SpO
2
is the source and it is unable to publish a value for pulse
rate, three dashes (- - -) are displayed in the Pulse Rate window.
NOTE: SpO
2
and pulse rate values are filtered by an averaging technique,
which determines how quickly the reported values respond to
changes in the patient’s saturation. Increased averaging time effects
time to alarm for SpO
2
saturation and pulse rate limits.
NIBP is the secondary source of pulse rate. Upon completion of a NIBP
determination, a pulse rate value is displayed in the Pulse Rate window. A pulse
rate value is displayed as long as the results of that determination are displayed
or until SpO
2
switches to operate mode.
NOTE: 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
determination.
When SpO
2
and NIBP are in operate mode, their associated alarms affect their
availability to act as the pulse rate source.
NOTES
 Because the various sources measure or derive pulse rate differently from
each other, when the monitor changes from one source to another the value
in the Pulse Rate window may change.
 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.
 If an SpO
2
-derived pulse rate is erratic, the pulse oximeter parameter may
be unable to measure the pulse and may cause an alarm.
Buttons Associated with Pulse Rate
There are no buttons associated with this parameter.
Windows Associated with Pulse Rate
The Pulse Rate window displays the pulse rate value in beats per min (bpm).
