In the traditional alarm management system, upper and lower
alarm limits are set so alarms are issued at specific SpO levels.

When the SpO level fluctuates near an alarm limit, each breach will
2
trigger an alarm. Aulisa GA1000 monitors the gradient, the depth and
the duration of SpO reduction as the factors to determine the alarm
2
triggering delay. Therefore, it helps to distinguish between major
clinical events and minor and brief SpO alarm limit violations that
2
may trigger an alarm.
NOTE:The following table lists the alarm triggering delay statistics
for SpO Low Alarm Limit.

NOTE:A countdown timer and "AUDIO OFF" button will be displayed
on the MAIN screen when the alarm limit has been breached
and the alarm is being delayed. The alarm will be delayed until
the timer counts down to zero.

Likewise, when the pulse rate fluctuates near an alarm limit, each
breach will trigger an alarm. With the pulse rate alarm delay feature,
Aulisa GA1000 allows a period of threshold violation of 7 seconds
before an alarm is triggered. Thus, it greatly reduces alarms reported
for minor and brief alarm limit violations.
