Displays, Indicators, and Controls
6
%rSO
2
Regional Hemoglobin Oxygen Saturation
%rSO
2
displays from 0 to 100% when a monitored channel is setup to
measure %rSO
2
or a regional sensor is attached to a signal processor.
The device continually displays an rSO
2
trendline for each monitored
channel. The channel background display flashes:
• Yellow during medium priority alarm conditions (equipment alarms
and rSO
2
values that are 5% or less above the rSO
2
low alarm
limit).
• Red during high priority rSO
2
alarm conditions (set by the high and
low rSO
2
alarm limits).
7
BL
Baseline
The baseline value displays below the %rSO
2
value for each monitored
channel. When the device is turned on, the BL display shows dashes
until the user sets the baseline values.
The user must set the baselines for each new patient.
• For instructions on setting the baseline values to the current rSO
2
values, see "Set Individual Baseline Values" on page 35.
• For instructions on setting the baseline values separately or to
make finite adjustments to the baseline value, see "Set Individual
Baseline Values" on page 35.
8
AUC
Area Under the Curve (cumulative saturation below low alarm limit)
For each channel, the rSO
2
values below the low alarm limit are
integrated together and displayed as the cumulative saturation below
low alarm limit, also known as AUC (Area Under the Curve). The value
is expressed in units of % minutes (%Min). When a baseline value is
changed, the AUC recalculates from the beginning of the current record.
The AUC will not calculate if a channel’s %rSO
2
Low setting is OFF.
NOTE: In order for the AUC display to match the Society of Thoracic
Surgeons (STS) database definition, the low alarm limit value for each
channel must be set to 75% of the patient's baseline.
9
%SpO
2
Percent Functional Hemoglobin Oxygen Saturation
%SpO
2
data displays from 0 to 100% when a channel is setup to
measure %SpO
2
or a pulse oximetry sensor is connected to the system.
The background of SpO
2
portion of the channel display flashes red
during high priority SpO
2
alarm conditions.
10
PR
Pulse Rate and Pulse Rate Bar Graph
Pulse rate data displays below the %SpO
2
display when a channel is
setup to measure pulse oximetry.
The background of pulse rate portion of the channel display flashes red
during high priority pulse rate alarm conditions.
