Abstract

The present disclosure may describe a system and method for displaying detailed information about a patient at a time selectable from a trend line of historic data. For example, the patient'"'"'s SpO₂, pulse rate, status, and so forth may be recorded over time. One or more trend lines of the recorded data over time may be displayed, and a user may select a point of interest from the trend line. Detailed data corresponding to that point of interest may then be displayed, for example, next to the trend line or on a separate screen. The detailed information may appear in the form of a pop-up box that does not obscure the trend line. In embodiments, the user may select the data point by moving a cursor or placing a pointing device on the trend line. The detailed information may be displayed automatically or may be activated by further user action.

Claims

1. A method, comprising:

displaying a trend line of physiological data on a first screen on a display of a physiological monitor;

receiving a user selection of a point on the trend line;

displaying information about the user-selected point on the display.

2. The method of claim 1, comprising determining the physiological data based on signals received from a physiological sensor.

3. The method of claim 1, wherein displaying information about the user-selected point comprises displaying a pop-up box on the first screen.

4. The method of claim 3, comprising displaying the pop-up box on the first screen such that no part of the trend line is obscured.

5. The method of claim 1, wherein displaying information about the user-selected point comprises displaying a second screen.

6. The method of claim 1, wherein the physiological data comprises a blood oxygen saturation and/or a pulse rate.

7. The method of claim 1, wherein the information about the user-selected point comprises a time stamp, a patient identification, a saturation pattern detection index, a patient status indicator, a monitor percent modulation, one or more monitor alarm limits, a sensor artifact indication and/or a sensor status indication.

8. A method, comprising:

selecting a point on a displayed trend line of physiological data to activate a display of additional information related to the trend line.

9. The method of claim 8, wherein selecting the point comprises moving an indicator along the trend line via one or more directional keys.

10. The method of claim 8, wherein selecting the point comprises positioning a virtual indicator representing a pointing device over the trend line.

11. The method of claim 8, wherein selecting the point comprises touching a display on which the trend line is displayed.

12. The method of claim 8, wherein selecting the point comprises placing an indicator at the point and sending a signal to indicate that the point has been selected.

13. The method of claim 8, wherein the physiological data comprises a blood oxygen saturation and/or a pulse rate.

14. The method of claim 85 wherein the information about the user-selected point comprises a time stamp, a patient identification, a saturation pattern detection index, a patient status indicator, a monitor percent modulation, one or more monitor alarm limits, a sensor artifact indication and/or a sensor status indication.

15. One or more tangible, machine-readable media comprising code which, if executed by a processor, cause the processor to render on a display of a physiological monitor:

a trend line of physiological data; and

additional information about a point on the trend lie upon user selection of the point.

16. The one or more tangible, machine-readable media of claim 15, comprising code which, if executed by a processor, cause the processor to render the additional information about the point adjacent to and not overlapping the rendered trend line.

17. The one or more tangible, machine-readable media of claim 15, comprising code which, if executed by a processor, cause the processor to render the additional information about the point in place of the trend line.

18. A physiological monitor, comprising:

a user input interface;

a display; and

a processor capable of at least displaying a trend line of physiological data on the display and displaying additional information about a point on the trend line upon selection of the point via the user input interface.

19. The monitor of claim 18, wherein the user input interface comprises a joystick, a trackball, an eraser mouse, and/or a point-and-click-mouse.

20. The monitor of claim 18, wherein the user input interface comprises the display.
