Alarms
The Astral device activates alarms to alert you to conditions that require attention to ensure patient
safety. When an alarm is activated, the Astral device provides both audible and visual alerts, and displays
an alarm message in the Alarm display on the Information bar.
As part of the alarm system (eg, the overpressure protection and system alarms), Astral may perform an
automatic restart. An automatic restart checks systems and ensures correct operation of the alarm.
As soon as the activation condition is met, the Astral device provides both audible and visual alerts
without delay.
