## Abstract

A regional oximetry system has a display and at least one processor causing a plurality of views to be displayed on the display, each configured to occupy at least a portion of the display. The views are adapted to present data responsive to at least one physiological signal. A first sensor port is configured to receive at least a first physiological signal representative of a regional tissue oxygenation level, and a second sensor port is configured to receive at least a second physiological signal representative of an arterial oxygen saturation level. One view presents a first trend graph of the first physiological signal and a second trend graph of the second physiological signal. An area between the first trend graph and the second trend graph can include a differential analysis of regional-to-central oxygen saturation.

## Claims

### Claim 1

A regional oximetry system comprising:
a display; and
at least one processor, the processor causing a plurality of views to be displayed on the display, each view configured to occupy at least a portion of the display, each of the views adapted to present data responsive to at least one physiological signal;
a first sensor port configured to receive a first physiological signal representative of a regional tissue oxygenation level;
a second sensor port configured to receive a second physiological signal representative of an arterial oxygen saturation level;
the processor configured to set a baseline level representative of an acceptable state of the regional tissue oxygenation;
wherein one of the views presents (i) a differential analysis of the regional tissue oxygenation level and the arterial oxygen saturation level, and (ii) the baseline level.

### Claim 2 (depends on 1)

The regional oximetry system according to claim 1 wherein the one of the views that presents the differential analysis presents a numerical representation of (i) the differential analysis and (ii) the baseline level as presently measured.

### Claim 3 (depends on 1)

The regional oximetry system according to claim 1 wherein the one of the views that presents the differential analysis presents a graphical representation of (i) the differential analysis and (ii) the baseline level.

### Claim 4 (depends on 3)

The regional oximetry system according to claim 3 wherein the graphical representation of the (i) differential analysis and (ii) the baseline level includes trend information.

### Claim 5 (depends on 1)

The regional oximetry system according to claim 1 wherein the one of the views that presents a differential analysis comprises a first view that presents a numerical representation of the (i) differential analysis and (ii) the baseline level, and the plurality of views also comprise a second view that presents a graphical representation of (i) the differential analysis and (ii) the baseline level.

### Claim 6 (depends on 1)

The regional oximetry system according to claim 1 wherein the processor further causes a set baseline menu view to be displayed on the display so as to occupy at least a portion of the display, and wherein the set baseline menu is adapted to present baseline display configuration information and baseline display configuration selections, the baseline menu comprising:
an enable toggle;
a baseline slider; and
a baseline spinner;
wherein the baseline slider and the baseline spinner are adapted to enable manual setting of the baseline level.
