Abstract

This disclosure describes improved systems and methods for displaying respiratory data to a clinician in a ventilatory system. Specifically, embodiments enable a clinician to visualize data from a variety of historical graphical representations associated with a selected historical time. That is, a cursor or other visual indicator may be provided that identifies the selected historical time on each of a plurality of historical graphical representations of respiratory data. Further, specific data values associated with the historical time and corresponding to a data point on each of the plurality of historical graphical representations may be highlighted for optimal display and comparison.

Claims

1. A method implemented by a ventilator for displaying respiratory data on a graphical user interface, the method comprising:

archiving a plurality of graphical representations of the respiratory data in sequential order during a time period;

receiving a selection of a historical time within the time period;

determining appropriate graphical representations of the archived plurality of graphical representations corresponding to the selected historical time; and

determining appropriate positions on the appropriate graphical representations corresponding to the selected historical time.

2. The method according to claim 1, further comprising:

displaying a visual indication at each appropriate position on each appropriate graphical representation corresponding to the selected historical time.

3. The method according to claim 2, wherein displaying the visual indication comprises displaying a cursor at each appropriate position on each appropriate graphical representation corresponding to the selected historical time.

4. The method according to claim 3, further comprising:

displaying one or more reference lines, wherein the one or more reference lines intersect the cursor and an axis of each appropriate graphical representation.

5. The method according to claim 3, further comprising:

displaying respiratory data associated with each appropriate position on each appropriate graphical representation corresponding to the selected historical time.

6. The method according to claim 1, wherein receiving a selection of the historical time further comprises:

providing a scrolling feature for scrolling through the archived plurality of graphical representations;

providing a scroll time that is continuously updated during scrolling, wherein the scroll time is associated with a sequential time during the time period; and

equating the scroll time with the selected historical time when scrolling stops.

7. The method according to claim 6, further comprising:

displaying a visual indication at each appropriate position on each appropriate graphical representation corresponding to the scroll time during scrolling.

8. A graphical user interface for displaying respiratory data, the ventilator configured with a computer having a user interface including the graphical user interface for accepting commands and for displaying respiratory data, the graphical user interface comprising:

at least one window associated with the graphical user interface;

one or more graphical representations of real-time respiratory data within the at least one window; and

one or more elements within the at least one window comprising at least a cursor element.

9. The graphical user interface of claim 8, wherein the one or more graphical representations of real-time respiratory data are sequentially archived over a time period to create one or more historical graphical representations.

10. The graphical user interface of claim 8, the one or more elements further comprising:

a pause element.

11. The graphical user interface of claim 10, wherein selection of the pause element initiates a pause mode that interrupts real-time display of the one or more graphical representations.

12. The graphical user interface of claim 9, wherein selection of the cursor element initiates a cursor mode that provides access to the one or more historical graphical representations.

13. The graphical user interface of claim 12, wherein the cursor mode further comprises:

receiving a selection of a historical time; and

displaying one or more visual indicators at positions on the historical graphical representations corresponding to the selected historical time.

14. The graphical user interface of claim 13, wherein receiving a selection of a historical time further comprises:

providing a scrolling feature for scrolling through the archived plurality of graphical representations;

providing a scroll time that is continuously updated during scrolling, wherein the scroll time is associated with a sequential time during the time period; and

equating the scroll time with the selected historical time when scrolling stops.

15. A ventilatory system for providing a graphical user interface for accepting commands and for displaying respiratory data, comprising:

at least one display device;

at least one processor; and

at least one memory, communicatively coupled to the at least one processor and containing instructions that, when executed by the at least one processor, provide a graphical user interface on the at least one display, comprising;

at least one window associated with the graphical user interface;

one or more graphical representations of real-time respiratory data within the at least one window; and

one or more elements within the at least one window comprising at least a cursor element.

16. The ventilatory system of claim 15, wherein the one or more graphical representations of real-time respiratory data are sequentially archived over a time period to create one or more historical graphical representations.

17. The ventilatory system of claim 16, wherein selection of the cursor element initiates a cursor mode that provides access to the one or more historical graphical representations.

18. The ventilatory system of claim 17, wherein the cursor mode further comprises:

receiving a selection of a historical time; and

displaying one or more visual indicators at positions on the historical graphical representations corresponding to the selected historical time.

19. The ventilatory system of claim 18, wherein receiving a selection of a historical time further comprises:

providing a scrolling feature for scrolling through the archived plurality of graphical representations;

providing a scroll time that is continuously updated during scrolling, wherein the scroll time is associated with a sequential time during the time period; and

equating the scroll time with the selected historical time when scrolling stops.

20. The ventilatory system of claim 18, wherein the cursor mode further comprises:

displaying one or more reference lines, wherein the one or more reference lines each intersect a visual indicator and an axis of a historical graphical representation corresponding to the selected historical time; and

,

displaying respiratory data associated with the visual indicators on the historical graphical representations corresponding to the selected historical time.
