ECG, arrhythmia, and ST segment
212 Instructions for use – Infinity Acute Care System – Monitoring Applications VG6.n
ECG parameter setup functions
All ECG setup functions take place in the ECG
pages.
NOTE
If excessive line frequency artifact is seen on the
ECG waveform, confirm that the correct Line
frequency has been set in the Biomed dialog.
For more information, refer to “Configuring the
biomed settings” in Instructions for use - Infinity
Acute Care System - Infinity M540 VG6.n.
WARNING
When the setting HR source is set to Auto, no
acoustic alarm signal is issued and no
message appears in the header bar when an
ECG lead wire is disconnected from the
patient.

Pulse tone
volume
Off, 5, 10 (default) to 100% in increments of
10%
Sets the volume of the pulse
tone.
Tone source – ECG (default)
–SpO2
Sets the source of the pulse
tone.
HR source – ECG (default) – derives the heart rate from
the ECG signal.
– ART – derives the heart rate from the arterial
blood pressure signal. The heart rate
parameter field label changes to APR and
appears in the color of ART.
– SpO2 – derives the heart rate from the pulse
oximetry signal. The heart rate parameter
field label changes to PLS and appears in
the color of SpO2.
– Auto – derives the heart rate either from the
ECG signal or other available sources. If an
ECG signal is not available, the M540
switches to ART, and then to SpO2.
Selects a different source for
the heart rate when the ECG
channel is unavailable due to
artifact resulting from surgical
procedures.
Waveforms 1, 2 (default), 3 Selects the number of
displayed waveforms.
