About Desat Index
The 3D Desat Index Alarm allows a clinician to request audible and visual alarms if a patient
experiences a specified number of desaturations beyond a defined level from the patient's
baseline saturation over a specific period of time.
Traditional high and low SpO

alarm limits alert clinicians to saturation levels that exceed
user-selected thresholds. These thresholds are typically established to detect significant
changes from patients’ baseline saturation levels. However, in select patient populations,
substantial desaturation events that remain above a typical low alarm limit threshold may be
preceded by a cycle of smaller transient desaturations over a limited period of time. The
ability to alert clinicians when a cycle of smaller transient desaturations occur may provide
an earlier indication of a potential significant decline in patient status, allowing for more
focused monitoring and/or a change in treatment.
