Alarms
10.4.1 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 MV low alarm is delayed in certain cases and is issued as follows:
– No sooner than 45 seconds after a case starts,
– No sooner than 45 seconds after changing to a mode with greater respiratory
support, see page 299,
– No sooner than 45 seconds after an Apnea (no flow) alarm or an Apnea
(no pressure) alarm.
10.4.2 Resetting the Apnea (no CO2) alarm
Prerequisite: The device has the "Integrated patient-gas measurement module"
option.
When changing to a ventilation mode with higher respiratory support, the Apnea
(no CO
2) alarm is reset. If the apnea situation persists, an alarm appears after the
time specified in table "Alarm delay and alarm escalation".
10.5 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.
