Adjusting the Settings in the Parameter Box
Turn Alarm Detection On or Off
You can turn on or off the alarm detection capability for the heart rate value. If HR ALARMS is on, an alarm will
be issued when the high or low alarm limit is violated. If you turn HR ALARMS off and the high or low alarm limit
is violated, an alarm will not be issued. When you turn off the monitor and turn it on again, HR ALARMS will be
reset to ON; the default setting is ON. See
Choose the Heart Rate Source
in this chapter for information regarding
the source of the measured value for heart rate.
To turn on or off the heart rate alarm detection:
Turn the rotary knob on the monitor to move the cursor. Highlight the ECG parameter box name and push
1.
the knob to access the ECG parameter menu.
Highlight HR ALARMS and push the knob to select.
2.
Choose ON or OFF and push the knob to select.
3.
Highlight MAIN MENU and push the knob to select.

Choose the Heart Rate Source
The Advisor® Vital Signs Monitor can measure the heart/pulse rate using two different parameters: ECG and
oximetry (SPO
2
). Regardless of the source, the measured value for heart rate can be continuously displayed in the
ECG box. You can choose the source (AUTO, ECG or SPO2) of the heart/pulse rate displayed. The default setting is
AUTO.
If you choose ECG, a small heart (
Q
) will flash in the ECG parameter box at the detection of each QRS complex
in the waveform. If you choose SPO
2
as the source, an asterisk (*) and a label identifying the source will be
displayed in the ECG parameter box at the detection of a pulse.
Figure 7.7: Heart Rate Source
If you choose AUTO, the monitor will determine the best source depending on the quality of available data and
the following source priority:
If ECG MONITOR is turned on using the ECG parameter menu, the ECG cable is connected to the monitor,
a.
and the ECG reading is valid, then ECG will be the heart rate source.
If ECG MONITOR is turned off or the signal is otherwise undetected, an oximetry cable (SPO
b.
2
) is connected
to the monitor, and the SPO
2
reading is valid, then SPO
2
will be the heart rate source.
To choose the source of the heart rate displayed in the ECG parameter box:
Turn the rotary knob on the monitor to move the cursor. Highlight the ECG parameter box name and push
1.
the knob to access the ECG parameter menu.
Highlight RATE SRC and push the knob to select.
