To view the active alarms:

priority.

Muting alarms

You can temporarily mute the audible alert on the Astral device for a two minute period. The Alarm
display and Alarm bar continue to display the alarm as usual. If after two minutes the alarm condition is
still present, the audible alert will sound again.

be helpful during suctioning procedures or when intending to disconnect the patient from the ventilator
for a short period.
If any of the following high priority alarms are triggered, the Alarm mute is automatically cancelled:
•
Total power failure
•
Critically low battery
• Incorrect circuit.
To mute the audible alert on an active alarm:

The alarm is silenced for two minutes. During that period,
flashes.
Note: Pressing the Alarm mute/reset button again during the Alarm Mute period will reset the displayed alarm. Refer
to Resetting alarms (see page 107).
