Abstract

Embodiments may include displaying a sparkline representing one or more physiological parameters measured by a patient monitoring system. The sparkline may be small and incorporated on a busy graphical user interface such as a ventilator display monitor. The sparkline may be utilized to display a baseline value in conjunction with a configurable amount of values, including, but not limited to a most recent or current value and prior values in order for a caregiver to interpret any differences at a glance. The sparkline may include a background area that represents a boundary and various aspects of the sparkline may be color-coded in order to indicate whether the boundary is exceeded. A channel indicator symbol may be included in the sparkline to indicate which channel is being monitored by the patient monitoring system. Further, the sparkline may be selectable in order to bring up more detailed information.

Claims

1. A system comprising:

a display; and

a processor configured to calculate and to cause the display of one or more physiological parameters of a patient on the display, the processor being configured to cause the display of at least one physiological parameter of the one or more physiological parameters as a sparkline on the display;

wherein the sparkline comprises a horizontal line representative of a baseline value of the at least one physiological parameter, one or more vertical lines representative of one or more past values of the at least one physiological parameter that extend perpendicularly from the horizontal line, and a vertical arrow representative of a current value of the at least one physiological parameter.

2. The system of claim 1, wherein the one or more vertical lines are representative of a past percent change in the value of the at least one physiological parameter relative to the baseline value.

3. The system of claim 2, wherein the vertical arrow is representative of a current percent change in the value of the at least one physiological parameter relative to the baseline.

4. The system of claim 1, wherein the horizontal line comprises a first side and a second side, wherein if any vertical line or the vertical arrow extends from the first side it represents a positive value change for the at least one physiological parameter, and if any vertical line or the vertical arrow extends from the second side it represents a negative value change for the at least one physiological parameter.

5. The system of claim 1, wherein the one or more past values of the at least one physiological parameter are within a period of time preceding the current value.

6. The system of claim 5, wherein the one or more vertical lines are axially offset along the horizontal line relative to one another, and a distance of an offset between adjacent vertical lines or between the vertical arrow and a vertical line represents a time interval between the respective values for the at least one physiological parameter.

7. The system of claim 1, wherein the one or more vertical lines are color-coded to indicate whether any of the past values of the at least one physiological parameter exceeds a boundary value for the at least one physiological parameter or whether any of the past values of the at least one physiological parameter falls within the boundary value and the baseline value.

8. The system of claim 7, wherein the boundary is set to twenty percent of the baseline reading by default.

9. The system of claim 1, wherein the vertical arrow is color-coded to indicate whether the current value of the at least one physiological parameter exceeds a boundary value for the at least one physiological parameter or whether the current value of the at least one physiological parameter falls within the boundary value and the baseline value.

10. The system of claim 1, wherein the sparkline comprises a background having a first color, and the processor is configured to change the first color to a second color to indicate that the current value of the at least one physiological parameter exceeds a boundary value for the at least one physiological parameter and to change the second color back to the first color if the current value of the at least one physiological parameter returns to within the boundary value and the baseline value.

11. The system of claim 10, wherein the at least one physiological parameter is regional oxygen saturation, and the background comprises an indicator of a channel from which a value of the regional oxygen saturation is obtained.

12. The system of claim 1, wherein a respective distance that the one or more vertical lines and the vertical arrow extend perpendicularly from the horizontal line represents a respective amount of change from the baseline value.

13. The system of claim 1, wherein the display comprises a graphical user interface, and the sparkline is configured to be selected by a user to cause display of additional information related to the at least one physiological parameter on the display.

14. The system of claim 1, wherein the system comprises a ventilator, and wherein the processor is configured to display the sparkline on the display along with a plurality of other ventilation parameters.

19. The method of claim 16, wherein the display comprises a graphical user interface, and the method comprises receiving a selection of the sparkline and displaying additional information related to the at least one physiological parameter on the display in response to the selection.

20.
