Heart Rate Alarm Limits
The heart rate is displayed in the upper right-hand corner of the screen.
Unless configured otherwise, heart rate alarms are preset at 30 bpm (bradycardia) and 150 bpm
(tachycardia). The low heart rate alarm limit range is 20 bpm to 100 bpm.
When the unit is monitoring a patient’s heart rate via ECG, the range for the high heart rate
alarm limit is 60 to 280 bpm with a default setting of 150 bpm. When the unit is monitoring a
patient’s pulse rate via pulse oximetry (SpO
2
), however, the unit automatically lowers the upper
limit for the high heart rate alarm to 235 bpm. The unit restores the original high heart rate
alarm limit when ECG monitoring resumes.
Vital Sign Alarms
Each vital sign has associated high and low alarm limits. You can set alarm limits for patient
heart rate and other optional monitoring parameters such as pulse oximetry (SpO
2
),
non-invasive blood pressure (NIBP), or end-tidal carbon dioxide monitoring (EtCO
2
), if
available.
The R Series unit has three levels of alarms:
• High Priority — Reflects physiological parameters that are out of bounds. When these
alerts occur, the unit emits a continuous audio tone, highlights the alarming parameter, and
flashes the associated alarm bell.
• Medium Priority — Reflects equipment- related, user correctable faults such as LEAD
OFF. The unit emits a two beep audio tone and displays a message for a timed period.
• Low Priority — Informational message only; the unit emits a two beep audio tone and
displays a message for a timed period.
Suspending and Silencing Alarms
When a high priority alarm occurs, the unit emits a continuous alarm tone, highlights the value
of the alarming parameter on the display, and flashes the bell icon associated with that
parameter.
You can either suspend the alarm tone for 90 seconds or you can silence the alarm tone.
Suspending Alarm Tones
To suspend an alarm tone for 90 seconds, press and release the ALARM SUSPEND
button in less than 1 second. The alarms tone stops, the unit displays an “X” across
the alarm’s flashing bell icon, and the value for the alarming parameter remains
highlighted. (If you press the ALARM SUSPEND button again, alarm processing is
reactivated.)
After 90 seconds, if the physiological parameter remains at a value that triggers the alarm, the
unit sounds the alarm tone again.
If the alarm condition clears (the physiological parameter returns to a value within
range) after you suspend the alarm tone, the unit resets the alarm and displays the bell
icon (no flashing, no “X”). The alarm parameter displays normally (no highlighting).
