Alarms

Activating the alarms related to volume

The upper alarm limit for MV is deactivated at the
start of the ventilation, but can be set during the
ventilation. The upper alarm limit for VTi is
automatically set to 130 % of the set VT in volume-
controlled ventilation modes. In pressure-
controlled ventilation modes, it is deactivated at
the start of the ventilation, but can be set during
the ventilation.
The MV low alarm is delayed in certain cases and
is issued as follows:
– No sooner than 90 seconds after a case starts,
– No sooner than 60 seconds after changing to a
mode with greater respiratory support, see
page 259.

Alarm delay and alarm escalation

To prevent unnecessary alarms, some alarms are
not displayed immediately after a limit violation, but
after a delay. In addition, certain circumstances
can cause the alarm priority to change.
