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.
