Database Operational Mode Screens
Operator's Manual 8-3
Definition : Indicates the cumulative integral of time and depth of desaturation events below the
threshold of 75% of the baseline rSO
2
value (relative decline of 25% below baseline) for the right
rSO
2
. Calculated by the cerebral oximeter by multiplying the difference between the threshold
and current rSO
2
values times the duration that rSO
2
is below the threshold. Values are accumu-
lated throughout the operation. Units are minute-percent. This is also called area under the curve
(AUC).
8.2.5
Field Name: Cerebral Oximeter Provided the First Indication
Format: Yes/No
Valid Data: Yes; No
Definition: Indicates whether the cerebral oximeter provided the first indication of a technical
problem or physiological change in the patient that could potentially lead to an adverse patient
outcome.
8.2.6
Field Name: Skin Closure Regional Oxygen Saturation—Left
Format: Integer
Valid Data: 1–99
Definition: Indicates the left cerebral regional oxygen saturation of blood (rSO
2
) value at the time
of skin closure at the end of the operation. Units are percent.
8.2.7
Field Name: Skin Closure Regional Oxygen Saturation—Right
Format: Integer
Valid Data: 1–99
Definition: Indicates the right cerebral regional oxygen saturation of blood (rSO
2
) value at the
time of skin closure at the end of the operation. Units are percent.

Database Operational Mode Screens
When the INVOS™ system is in Database operational mode, there are screens that differ or are
additional from Normal mode. Those different or additional screens include the following:
•
Start screen in Database operational mode
•
Main screen in Database operational mode displaying AUC
•
Tabular trends for entering Induction time screen
•
Tabular trends for entering Skin closure time screen
