Database Variable and Fields
8.2.1
Field Name: Preinduction Baseline Regional Oxygen Saturation—Left
Format:
Integer
Valid Data:
1-99
Definition:
Indicates the percent baseline left cerebral regional oxygen saturation (rSO
2
) values
at the beginning of the operation, when the patient is awake and functional. Patient can be
sedated or on supplemental oxygen at the time measurement is taken. In the absence of a user-
specified baseline, the cerebral oximeter will automatically select a baseline value from the first
few minutes of the case.
8.2.2
Field Name: Preinduction Baseline Regional Oxygen Saturation—Right
Format:
Integer
Valid Data:
1–99
Definition:
Indicates the percent baseline right cerebral regional oxygen saturation (rSO
2
) values
at the beginning of the operation, when the patient is awake and functional. Patient can be
sedated or on supplemental oxygen at the time measurement is taken. In the absence of a user-
specified baseline, the cerebral oximeter will automatically select a baseline value from the first
few minutes of the case.
8.2.3
Field Name: Cumulative Saturation Below Threshold—Left
Format:
Integer
Valid Data:
0–9999
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 left
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).
8.2.4
Field Name: Cumulative Saturation Below Threshold—Right
Format:
Integer
Valid Data:
0–9999
