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 option includes a user-selectable 3D 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 in
