Adaptive Threshold alarm (ATA) Feature
The Adaptive Threshold Alarm (ATA) feature is an optional feature that
provides continuous SpO
2
surveillance while allowing the clinician a useful
tool to help reduce the frequency of audible alarms.
ATA establishes the alarm limit threshold based upon the patient-specific
baseline value
of the SpO
2
parameter which is determined from the
recent history of SpO
2
values. An
Adaptive Threshold Limit
is continuously
determined for the patient and SpO
2
values outside the Adaptive
Threshold Limit trigger an audible alarm. The Adaptive Threshold Limit is
bound by the standard SpO
2
low alarm limit and the Rapid Desat low
alarm limit. SpO
2
values that exceed the Rapid Desat limit, whether it
occurs rapidly or not, will activate an audible alarm.
Prior to activating ATA, review and select the appropriate standard low
alarm limit and other alarm settings. Once ATA is selected, the Rapid
Desat Alarm protection is always active. If the ATA low alarm limit is
violated, ATA generates an audible alarm.
It is important to note that once activated, ATA has the following
automatic safety features:
Reminder Tones
If an SpO
2
value from a patient drops below the standard low alarm limit
set by the user, a visual alert will display and a reminder tone will repeat
every 15 minutes as long as the condition persists. If the SpO
2
value
drops below the ATA low alarm limit, an audible alarm will be activated.
Rapid Desat Alarm Protection
The Rapid Desat feature is always active when ATA is turned on. This
means that deep desaturations (5% or 10%) from the standard SpO
2
low
alarm limit immediately generate an audible alarm. When used with ATA,
