Arrhythmia monitoring overview
The M540 performs arrhythmia monitoring on adult
and pediatric patients and relays these values to
the Cockpit for display. Arrhythmia monitoring is not
available for neonates. To make sure that asystole
and ventricular fibrillation alarms are reported even
when heart rate alarm monitoring and arrhythmia
monitoring is deactivated, set the ASY/VF alarms
selection in the General settings page to Always
on (see page 458).
The selected arrhythmia mode (see page 221)
controls which arrhythmia parameters are
monitored and how they are displayed. Each
occurrence of an arrhythmia event is stored in the
Alarm history page provided the archive setting is
configured (see page 139).
Refer to the instructions for use Infinity Acute Care
System – Infinity M540 for a detailed description of
the M540 arrhythmia functions.
WARNING
When HR alarm and arrhythmia monitoring
are deactivated and the ASY/VF alarms setting
is set to Follow HR alarm, the monitor does
not generate asystole or ventricular fibrillation
alarms. To make sure that ASY/VF alarms are
always generated, set the ASY/VF alarms
setting to Always on.
