Abstract

Embodiments of the present invention include systems and methods for display and navigation of a clinical decision support process with portions thereof on separate display screens, as well as systems and methods for dynamically changing visual characteristics of softkeys on a patient monitor/defibrillator user interface screen based on clinical decision support or differential diagnosis processes, as well as a code review interface configured to permit a user to see what was displayed on a patient monitor/defibrillator user interface screen at any time during a medical event, as well as to see snapshots of other recorded parameters over the course of the medical event for purposes of code review, patient transfer, and improved patient care.

Claims

1. A method for code review of a medical event, the method comprising:

displaying, on a first device screen, a user interface during the medical event;

recording images of the user interface, each of the images representing an entirety of the user interface associated with a time during the medical event, wherein the images are recorded at least once every second;

displaying, on a second device screen, a visual timeline indicator and a user interface replicator, the user interface replicator displaying the images of the user interface and the visual timeline indicator representing a time associated with each of the images, wherein the visual timeline indicator and the user interface replicator permit sequential playback and review of the user interface images from the medical event, and wherein the visual timeline indicator accepts user input to move the sequential playback to a different time associated with the medical event.

2. The method of claim 1, wherein the visual timeline indicator includes a timeline including a beginning time of the medical event and an end time of the medical event, the method further comprising indicating on the timeline the time associated with the image of the user interface shown in the user interface replicator.

3. The method of claim 2, wherein the indicating on the timeline comprises using an indicator on the timeline to indicate the time associated with the image of the user interface shown in the user interface replicator.

4. The method of claim 3, further comprising advancing the indicator along the timeline in a direction from the beginning time toward the end time during sequential playback of the user interface images.

5. The method of claim 4, wherein the visual timeline indicator accepts user input by permitting scrolling of the indicator to a different position along the timeline.

6. The method of claim 2, wherein the visual timeline indicator displays the time associated with each of the images in an hour-minute-second format.

7. The method of claim 2, wherein the visual timeline indicator includes one or more event markers marking occurrence of clinically-relevant sub-events during the medical event.

8. The method of claim 7, wherein the one or more event markers include a drug event marker indicating a time at which a drug was administered to a patient during the medical event.

9. The method of claim 7, wherein the one or more event markers include a defibrillation event marker indicating a time at which a defibrillation shock was applied to a patient during the medical event.

10. The method of claim 7, wherein the one or more event markers include an ROSC event marker indicating a time at which a patient returned to spontaneous circulation.

11. The method of claim 7, wherein the one or more event markers include a rearrest event marker indicating a time at which a patient returned to cardiac arrest.

12. The method of claim 7, wherein the one or more event markers include an alarm event marker indicating a time at which an alarm was activated.

13. The method of claim 1, further comprising displaying a cursor on the second device screen and, when the cursor is hovered over or near a time represented by the visual timeline indicator, displaying on the second screen at or near the cursor the image of the user interface associated with the time.

14. The method of claim 13, further comprising, when the cursor is hovered over or near the time, displaying at or near the cursor a textual representation of the time.

15. The method of claim 1, wherein the second device screen is integrated with a heads up display.

16. The method of claim 1, wherein the second device screen is integrated with a wearable device.

17. The method of claim 1, wherein the second device screen is integrated with a hands-free device.

18. The method of claim 1 wherein the second device screen is projected onto a user'"'"'s glasses or face shield.

19. A method for decision support during a medical event, the method comprising:

displaying, on a screen on a device, a user interface during the medical event, wherein the user interface comprises two or more softkeys each representing a possible user selection;

collecting physiological data from a patient with the device;

identifying, based on the physiological data, a type of the medical event;

determining, in response to the type of the of the medical event, which one of the two or more softkeys represents the possible user selection that most closely conforms to a treatment or diagnosis protocol; and

based on the determination, visually distinguishing the one of the two or more softkeys from the others of the two or more softkeys on the user interface.

20. The method of claim 19, wherein visually distinguishing the one of the two or more softkeys comprises making the one of the two or more softkeys larger than the others of the two or more softkeys.

21. The method of claim 19, wherein visually distinguishing the one of the two or more softkeys comprises changing a position of the one of the two or more softkeys on the user interface.

22. The method of claim 19, wherein visually distinguishing the one of the two or more softkeys comprises changing a color of the one of the two or more softkeys on the user interface.

23. The method of claim 19, wherein visually distinguishing the one of the two or more softkeys comprises changing a border of the one of the two or more softkeys on the user interface.

24. The method of claim 19, wherein visually distinguishing the one of the two or more softkeys comprises making the one of the two or more softkeys dynamically flash on the user interface.

25. The method of claim 19, wherein visually distinguishing the one of the two or more softkeys comprises displaying on the screen a legend describing why the one of the two or more softkeys has been visually distinguished.

26. The method of claim 25, wherein the one of the two or more softkeys is a cardiac distress softkey, and wherein the legend textually indicates a possible cardiac arrhythmia.
