9.12 Alarm Logbook
For alarm logbook, the system provides up to 500 events which are stored in chronological
order. When a new event occurs after 500 events are already stored, the earliest event will be
overwritten by the new one. Each alarm log includes the ventilation mode, ventilation type
(NIV or non-NIV), patient type (adult or pediatric), operating mode (standby or non-standby
mdoe), and monitored parameters.
To access the Alarm Logbook window, push the Alarm Setup key and select [Alarm
Logbook]. In the Alarm Logbook window, you can:
1. Select [Scroll] to view the alarm events item by item.
2. Select [Alarm Level] and select the desired level of alarms to be displayed. The options
include all level, high level, medium level, and low level.
NOTE
After the ventilator is started up, if [Same Patient] is applied, the system will store
the previous alarm log and continue recording. If [New Patient] is applied, the
system will clear the previous alarm log and record anew.
