Silencing Alarms
The operator may decide, based on their clinical assessment, to silence certain alarms that, in
the given situation, are considered “nuisance” alarms and do not assist in the safe management
of the patient. Before any alarms can be silenced, the operator receives a Pop Up message
asking them to confirm their understanding that the alarm is no longer available in the current
operating session.
Alarm Preemptive Mute upon Power up
When the unit is first powered up, certain patient circuit alarms are preemptively muted for 120
seconds, to allow the operator time to get the patient circuit properly adjusted without nuisance
alarms.
Note:
During this preemptive mute of this audible alarm, the LED alarm light and alarm
message are still indicated.
There is a countdown timer located under the muted alarm symbol, showing how much time of
the 120 seconds is remaining. The alarms that have this preemptive mute are:
