ECG, arrhythmia, and ST segment
214 Instructions for use – Infinity Acute Care System – Monitoring Applications VG6.n
Filter – Off – provides the greatest sensitivity to
noise or artifact (the message Filter off
appears in the waveform channel).
– Monitor (default) – recommended for
standard monitoring; reduces wandering
isoelectric line, muscle artifact, and power
line interference. No message appears in
the waveform channel.
– ESU – reduces signal distortion during
electrosurgery (the message Filter ESU
appears in the waveform channel).
12-lead monitoring is not available when the
ESU filter is enabled. Likewise, the ESU filter
selection is not available when you are using 12-
lead monitoring.
Controls the sensitivity to
various artifact sources.
When the M540 is in OR
mode and the filter selection
is set to Monitor:
– the hardware low pass
ESU filter is activated
– RRi is unavailable
– 12-lead ECG monitoring is
unavailable
None of these filter settings
are of diagnostic quality.
Pacer detection
(Not available in
neonatal mode)
– On (default)
– Off – the message Pacer off appears in the
waveform channel
– Fusion – the message Pacer fusion
appears in the waveform channel
Determines whether pacer
impulses are detected. See
“Pacer fusion mode“on
page 217 for precautions
before you start this mode.
QRS sync
marker
– On – displays QRS synchronization markers
– Off (default)
Determines whether vertical
white markers appear on the
waveform to identify QRS
complexes. The markers help
determine when it is safe to
perform synchronized
cardioversion.
