Alarms and Messages

Desat Index Alarm

Traditional high and low SpO

alarm limits alert clinicians to saturation levels that exceed user-

selected thresholds, and these thresholds are typically established at a considerable change

from the patients’ baseline saturation level. However, in select patient populations, substantial

desaturation events that exceed a typical low alarm limit threshold may be preceded by a cycle

of transient desaturations over a limited timeframe, and the ability to alert clinicians to a cycle of

these smaller desaturations may provide an earlier indication of a potential significant decline in

the patient’s status and the need for more focused monitoring and/or a change in treatment.

To address patient populations at risk for cyclic, moderate desaturations, the 3D ALARM option

includes a user-selectable Desat Index Alarm which allows the clinician to request an audible and

visual alarm in the event the patient experiences a specified number of desaturations beyond a

defined level from the patient’s baseline saturation over a specific window of time, with each of

these variables selectable by the user within established ranges as noted below:

Desat Index Threshold: Range of 2% to 10% in 1% increments, default of 4%

Desat Index Timeframe: Range of 1 to 4 Hrs in 1-Hr increments, default of 1 Hr

Desat Index Alarm/Quantity: Range of 1 to 25 desaturations, default is OFF

To translate the above Desat Index variables and ranges into perspective, consider a patient

at risk of respiratory compromise with the definition for respiratory compromise of 5 or more

transient moderate desaturations (associated with a 4% drop in SpO

) per hour. To request a

Desat Index alarm for this situation, the clinician would set the Desat Index variables as follows:

Desat Index Threshold: 4%

Desat Index Timeframe: 1 hour

Desat Index Alarm 5 (desaturations)

Post-operative patients receiving pain medication may be predisposed to respiratory depression.

If the patient has an underlying respiratory condition, pain medication may cause the patient to

spiral into a cascade of cyclic desaturations, which initially are mild but may worsen quickly. The

Desat Index Alarm may give an early warning of this type of respiratory disturbance that can lead

to respiratory depression and even arrest.

CAUTION: THE DESAT INDEX ALARM IS INTENDED AS AN ADJUNCT RATHER THAN IN

PLACE OF THE LOW SATURATION ALARM.
