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.
Core Innovation
The invention provides a regional oximetry system equipped with a display and at least one processor that presents multiple configurable views, each occupying at least a portion of the display. These views show real-time and trend data derived from physiological signals, including regional tissue oxygenation and arterial oxygen saturation levels received via sensor ports. A main feature of the user interface is the ability to display both the trend of regional tissue oxygenation and the trend of arterial oxygen saturation, as well as a differential analysis (e.g., the difference between the two values), which is visually and numerically represented between their respective trend graphs.
This system addresses clinical challenges identified in the background, such as the confusing interpretation of multiple sensor signals and the risk of mislabeling sensor locations, by providing a user interface that presents graphical connectivity statuses of sensors, sensor pods, and sensor ports. Visual human form representations enable clinicians to correctly assign and confirm sensor placements for both adults and children, reducing the possibility of misreading physiological data. Additional views and controls facilitate setting sensor-specific baselines, adjusting display settings, and configuring alarm conditions.
The enhanced user interface includes interactive touchscreen controls supporting a range of gestures for navigation and configuration. The system provides graphical and numerical feedback concerning sensor connectivity, sensor placement, and differential metrics such as the difference between regional and arterial oxygenation or between measured and baseline oxygen levels. By unifying sensor connectivity and physiological data presentation in an integrated display, the system aims to improve clinician interaction and ensure correct interpretation of regional oximetry measurements.
Claims Coverage
There is one independent claim that describes the main inventive features of the regional oximetry system.
Set sensor menu view displaying connectivity status
The system includes a display and a processor that creates multiple views, with at least one set sensor menu view that occupies at least a portion of the display. The set sensor menu view is adapted to present the connectivity status of the sensor port and at least one sensor. Additionally, a pod array, adapted to communicate with the at least one sensor and the sensor port, is part of the system. The set sensor menu view also presents the connectivity status of the pod array, sensor port, and at least one sensor.
The independent claim centers on a user interface for a regional oximetry system, specifically a set sensor menu view that graphically and interactively displays connectivity status information for the sensor port, sensor(s), and pod array.
Stated Advantages
The user interface addresses potential confusion and risk associated with multiple sensors and pod assemblies by clearly displaying information about the connectivity and configuration of sensors, pod assemblies, and channel ports.
Visual representations, such as human forms and explicit connectivity status, assist clinicians in properly labeling and configuring the system, reducing the risk of misreading physiological data.
Multiple views, including graphical and numerical differential analyses, enable clinicians to accurately interpret and respond to regional and arterial oxygenation data, enhancing patient safety.
Documented Applications
Continuous assessment of tissue oxygenation beneath sensors placed on a patient, such as on the forehead, forearm, chest, upper leg, or abdomen, to help clinicians detect regional hypoxemia.
Simultaneous measurement and differential analysis of regional tissue oxygen saturation (rSO2) and arterial oxygen saturation (SpO2) for use in monitoring and maintaining brain oxygenation and safe cerebral perfusion during procedures.
