7.6.2 Choose the Heart Rate Source
The 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 HR parameter 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, the primary lead label (II) will show in the HR parameter
box at the detection of each QRS complex in the waveform. If you choose SpO
2
as the source, the SPO2 label identifying the source will be displayed in the HR
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:
a. If the ECG cable is connected to the monitor, and the ECG reading is valid,
then ECG will be the heart rate source.
b. If ECG cable is not connected or the signal is otherwise undetected, an
oximetry cable (SpO
2
) is connected to the monitor, and the SpO
2
reading is
valid, then SpO
2
will be the heart rate source.
