Understanding Differences in Heart Rate Alarms
The possible differences between ECG-based heart rates at the Acuity Central Station and
the bedside ECG monitor can affect the frequency of heart rate alarms. For example,
when heart rate alarm limit settings are the same at the Acuity Central Station and the
bedside monitor, the bedside monitor could display a higher heart rate (due, perhaps, to
noise or artifact) and present a heart rate alarm event at bedside.
For patients monitored using a Propaq CS or Encore monitor, if a high-quality pulse
oximetry waveform is available for the patient, you can try selecting pulse rate oximetry
as the heart rate source. This may result in a more accurate heart rate, thereby reducing
erroneous or nuisance heart rate alarm events at the bedside monitor.
To select pulse rate oximetry as the heart rate source:
• From Main Menu, press SETUP, MORE to access Setup Menu 2.
• Press NEXT as needed to highlight the HR/PR selection for SELECTED SOURCE
(typically set to ECG).
• Press CHANGE as needed to highlight SpO2.
• Press Home or MAIN MENU key to exit.
Acuity Message for Monitor Heart Rate Alarm
If a heart rate alarm occurs at the bedside monitor but does not occur at the Acuity
Central Station for a defined period of time (see table below), the Acuity Central Station
displays an equipment alert to inform the operator of this condition:
When the heart rate alarm is no longer occurring at the bedside monitor, the Acuity
system dismisses this message. The operator can also dismiss the message.
