Alarm Categories

AVEA ventilator alarms are grouped into three categories:

High priority (warning)

This category of alarm requires immediate action. For a high priority alarm, the alarm indicator is RED and the alarm icon
flashes at a rate of 2 Hz (fast). A high priority alarm sounds a series of five tones, three low and two high, repeated at
intervals of 6 seconds.

Medium priority (caution)

A medium priority alarm displays a yellow indicator and the alarm icon flashes at ½ Hz (slow). A medium priority alarm
sounds three tones, all at the same pitch, repeated at intervals of 20 seconds.
Low priority (advisory)
A low priority alarm (or advisory) displays a yellow indicator and the alarm icon does not flash.
A low priority alarm sounds a single tone, which is not repeated
There are visual displays for all categories of alarms. A text message appears in the indicator at the upper right of the
touch screen.
The alarm icons flash until the cause of the alarm is no longer present. Both high and medium priority alarms that have
been resolved will appear as a solid yellow message indicator with no icon displayed until the Alarm Reset button is
pressed. (See Table 7–1 on page 178 for alarm messages.)
Multiple alarms can be displayed simultaneously. If 2 or more alarms are current, a white triangle appears on the right of
the alarm indicator/message. Touching the screen over the triangle will open a drop down box for display of up to nine
alarm messages. In the event that there are more than nine active or resolved alarms available for display, the nine
highest priority alarms will be displayed.
To close the drop down box and display a single alarm message, touch the triangle again.
Alarm messages are prioritized in order of appearance, the highest priority alarm is always displayed in the top position
of the alarm indicator display.
