10 Alarms
10.1 Introduction
Alarms, triggered by a vital sign that appears abnormal or by technical problems of the
ventilator, are indicated to the user by visual and audible alarm indications.
NOTE
When the ventilator is started, the system detects whether audible alarm tones and
alarm lamp function normally. If yes, the alarm lamp flashes red and yellow
successively, and the speaker and the buzzer give check tones. If not, do not use the
equipment and contact us immediately.
When multiple alarms of different priorities occur simultaneously, the ventilator
selects the alarm of the highest priority and gives visual and audible alarm
indications accordingly.
When multiple alarms of same levels occur simultaneously, the alarm messages are
displayed in order of time of occurrence.
The ventilator restore the latest configuration if restarts within 60 seconds after the
power failure. And it will restore the user configuration rather than the latest
configuration if restarts 120 seconds later after the power failure. The ventilator
may load either the latest configuration or the user configuration if restarts from
60-120 seconds after the power failure.
If the equipment power failure lasts for not more than 30 s, the alarm settings prior
to the power failure are restored when the equipment is powered on again.
WARNING
A potential hazard can exist if different alarm presets are used for the same or
similar equipment in any single area, e.g. an intensive care unit or cardiac
operating room.
