Adaptive Threshold Alarm (ATA) Feature
The Adaptive Threshold Alarm (ATA) feature is an optional feature that provides continuous
SpO2 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 SpO2 parameter which is determined from the recent history of SpO2 values. An
Adaptive Threshold Limit is continuously determined for the patient and SpO2 values
outside the Adaptive Threshold Limit trigger an audible alarm. The Adaptive Threshold
Limit is bound by the standard SpO2 low alarm limit and the Rapid Desat low alarm limit.
SpO2 values that exceed the Rapid Desat limit, whether it occurs rapidly or not, will activate
an audible alarm.
Prior to activating ATA, please 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 SpO2 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 SpO2 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 SpO2 low alarm limit immediately generate an
audible alarm. When used with ATA, it also serves as absolute low alarm limit protection.
SpO2 values exceeding the Rapid Desat low alarm limit, whether rapid or not, will activate
an audible alarm. You can change the Rapid Desat default setting from 5% to 10%. ATA does
not allow a Rapid Desat default setting of 0%.
When ATA is turned Off, the instrument uses the standard alarm limits and standard alarm
delays.
