Chapter 3 Ventilator Alarms
19
There are three types of alarms:
• High Priority – Require immediate response by the operator
• Medium Priority – Require prompt response by the operator
• Low Priority – Require operator awareness. These alarms alert you to a change in the
ventilator status.
Additionally, the ventilator also displays informational messages and conrmation alerts that notify
you of conditions that need attention but do not qualify as alarm conditions.
Note: If multiple alarms occur at the same time, all alarms are processed and displayed, but the alarms are ordered
rst by priority and then by occurrence, with the newest, highest priority alarms at the top of the list. The alarm
precedence is in the following order: high priority, medium priority, low priority, and informational messages.
Note: Not all alarms are available in every therapy mode; some alarms are mode-dependent.
3.1 Audible and Visual Alarm Indicators
When an alarm condition occurs:
• The alarm LED indicator on the Alarm Indicator/Audio Pause button lights
• The audible alarm sounds
• A message appears on the screen describing the type of alarm
Each of these is described in detail below.

The Alarm Indicator/Audio Pause button on the front of the ventilator lights up as follows whenever
an alarm is detected:
• Red Flashing Indicator – When the device detects a high priority alarm, the Alarm
Indicator/Audio Pause button ashes red.
• Yellow Flashing Indicator – When the device detects a medium priority alarm, the Alarm
Indicator/Audio Pause button ashes yellow.
• Yellow Solid Indicator – When the device detects a low priority alarm, a solid yellow light
