Instructions for use Primus Infinity Empowered SW 4.5n 131
Alarms
If an apnea monitoring feature derived from a spe-
cific monitoring parameter has been disabled, that
parameter will be marked with the symbol .
A monitoring parameter is always marked with the
symbol if, after switching from Standby into a
ventilation mode, a valid CO
2 breathing phase has
not yet been detected for the parameters O
2, N2O,
MV, or inspiratory and expiratory CO2, or, respec-
tively, a valid pulse signal for SpO2. As soon as a
breathing phase has been detected or valid pulse
signals are available for SpO
2, the symbol disap-
pears.
The series of alarm tones can be suppressed for
2 minutes:
z Press the key (C), the yellow LED lights up.
The symbol appears in the system information
field (D) next to the date with an indication of the si-
lence time remaining (minutes:seconds).
To enable the alarm tone:
z Press the key (C), the yellow LED turns off.
Alarm behaviour when changing ventila-
tion modes
The Primus Infinity Empowered has an automatic
suppression of active MV low and apnea alarms im-
plemented, when changing ventilation modes.
This suppression applies when the user changes
from a ventilation mode with a low mandatory ven-
tilation support, such as Man.Spont., to a ventila-
tion mode with a higher mandatory ventilation, such
as Volume Mode. After this timeout the alarms will
only be generated again if the preconditions are
valid.
If the MV low alarm is active during such a change,
the alarm is suppressed for 45 seconds (no alarm
display and no audible tone). The apnea alarms
can be suppressed for a certain time, depending on
the ventilation settings in the new ventilation mode.
If the setting for Freq./Freq
MIN is <6 1/min, the ap-
nea alarms will be suppressed for 30 seconds. In
all other cases, they will be suppressed for
15 seconds.
