Special alarm behavior
Activating any of the following features alters the
normal alarm annunciation behavior:
– ASY/VF alarms
– SpO2 desaturation alarm
– NIBP/SpO2 interlock function
– Zeroing invasive blood pressures
– Privacy, Standby, Cardiac bypass, and OR
modes
– French NFC mode
ASY/VF alarms
You can control the alarming behavior for
ventricular fibrillation (VF) and asystole (ASY)
alarms.
To make sure that asystole and ventricular
fibrillation alarms are always reported do one of the
following:
– Turn arrhythmia monitoring on
or
– Set the
HR source
to
ECG
(see page 212)
when the
ARR mode
setting is set to
Off
(see
page 225)
If you select
Follow HR alarm,
deactivate HR and
arrhythmia alarm monitoring, the message
HR,
ASY, VF off
appears.
SpO2 desaturation alarms
The alarm priority is upgraded to high-priority if the
SpO2 value falls below the Desat. alarm limit.
Deactivating the SpO2 alarm automatically
deactivates the desaturation alarm. The
desaturation alarm can be activated only if SpO2
alarms are activated (see page 148, page 263, and
page 277). When using the Infinity MCable –
Nellcor OxiMax, this feature is only available if the
SatSeconds alarm
function is set to
Off
(see page
279).
NIBP/SpO

interlock alarms
To avoid SpO2 false alarms when the blood
pressure cuff and the SpO2 sensor are placed on
the same limb during an active non-invasive blood
pressure measurement, select the
NIBP/SpO2
interlock
function
in the
General settings
page
(see page 458).
When the function is activated, all SpO2 alarms are
deactivated during an active non-invasive blood
pressure measurement. To activate or deactivate
this function, see page 460.
